A quantitative review of the health record for missing reports and signatures that occurs when the patient is in the hospital is referred to as a review

Answer:

We know that, the kinetic energy

ke=  \frac{1 }{2} m{v}^{2}  

and we also know that the acceleration causes the speed's value to be doubled

Hence, v becomes 2v

When 2v is squared, it becomes 4v^2. After substituting this value in the equation above and comparing it,

We can conclude that the Kinetic Energy has increased

by a factor of 4

Answer:

she rode for 166.66 seconds , which is about 2 minutes and 47 seconds

Explanation:

We use the kinematic equation that relates initial and final velocities with time and distance travelled that is shown below:

[tex]distance=\frac{(v_i+v_f)*t}{2}[/tex]

which in our case gives:

[tex]distance=\frac{(v_i+v_f)*t}{2}\\500=\frac{(0+6)*t}{2}\\500=3*t\\t=\frac{500}{3} \,s\\t\approx 166.66\,sec[/tex]

which reduced to minutes gives 2 minutes and approximately 47 seconds

Answer:

1. Gravity

2. Increases

Explanation:

Gravity is the force that attracts all objects toward each other. This is the force that keeps us grounded on Earth instead of floating in the air.

Although people have gravitational forces, the attraction force is a negligible amount. However, as the mass of the objects are increased, they will exert  far greater gravitational powers to other objects or individuals such as humans.  

Answer:

6.28 * 10⁴ m/s

Explanation:

Using the relation :

Given :

Radius, R = 10km

Period, T = 1.0 s

v = (2πR) / T

Where v = velocity of a point

R in meters ;

1km = 1000m = 10³m

10km = 10 * 10³m = 1 * 10^4 m

v = (2π*10^4m) / 1 s

v = 6.2831853 * 10⁴ m/s

v = 6.28 * 10⁴ m/s

Answer:

The block moves at 1.25 m/s

Explanation:

Law Of Conservation Of Linear Momentum

It states the total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and speed v is  

P=mv.  

If we have a system of two bodies, then the total momentum is the sum of the individual momentums:

[tex]P=m_1v_1+m_2v_2[/tex]

If a collision occurs and the velocities change to v', the final momentum is:

[tex]P'=m_1v'_1+m_2v'_2[/tex]

Since the total momentum is conserved, then:

P = P'

Or, equivalently:

[tex]m_1v_1+m_2v_2=m_1v'_1+m_2v'_2[/tex]

The bullet of m1=0.049 kg moves at v1=421 m/s. Then it strikes a wooden block of m2=4.7 kg originally at rest (v2=0).

After the collision, the bullet continues at v1'=301 m/s. The speed of the block can be calculated by solving for v2':

[tex]\displaystyle v'_2=\frac{m_1v_1+m_2v_2-m_1v'_1}{m_2}[/tex]

[tex]\displaystyle v'_2=\frac{0.049*421+0-0.049*301}{4.7}[/tex]

Calculating:

[tex]\displaystyle v'_2=\frac{5.88}{4.7}=1.25\ m/s[/tex]

The block moves at 1.25 m/s

Answer:

a) Δd=v₂Δt+[tex]\frac {1}{2}[/tex]aΔt²

v₂=0 (hits ground)

Δd=[tex]\frac {1}{2}[/tex]aΔt²

Δt²=Δd÷[tex]\frac {1}{2}[/tex]a

t=√25÷[tex]\frac {1}{2}[/tex](9.8)  9.8m/s²=gravity

t=5÷4.8

t=1.04s

b) a=[tex]\frac{v_2-v_{1} }{t}[/tex]

a×t=v₂-v₁

v₂=(a×t)+v₁

v₂=(9.8×1.04)+20

v₂=10.192 + 20

v₂=30.192

v₂=30.2m/s rounded

Explanation:

A star is in equilibrium when the pressures inside the star balance out the force of gravity. The pressure is thermal pressure resulting from the fusion reactions taking place in the star's core. A star stays in equilibrium until the supply of hydrogen in the core is depleted.

In a stable star, the gas pressure pushing out from the center is equal with the gravity pulling atoms inward to the center – when these forces are equal, the star is at equilibrium. Once a star reaches equilibrium for the first time, it will start burning (fusing) hydrogen into helium.

Answer: It has enough mass to resist expansion.

Answer:

the cost to leave the lights on 24 hours a day for one year is 31,536 cents or 315.36 dollars

Explanation:

Given that;

P = 300 watts = 300/1000 = 0.3

t = 24hrs a day

In a calendar year, we have 365 days

so;

E = 0.3 × 365 × 24

E = 2628 KWh

given that;  1 KWh = 12 cent

then 2628  KWh is x

x = 2628 × 12

x = 31,536 cents or 315.36 dollars

Therefore, the cost to leave the lights on 24 hours a day for one year is 31,536 cents or 315.36 dollars

Answer:

  fr = 245 N,  T = fr

Explanation:

We can solve this exercise using the equilibrium conditions, let's start by creating a reference system

where we call T the drag force of the gorilla, m the mass of the trunk and μ the coefficient of kinetic friction

Y axis  

           N- W =

           N = W = mg

X axis

          T - fr = 0

          T = fr

the expression for the friction force is

          fr = μ N

          fr = μ mg

we substitute

           T = μ m g

When analyzing these expressions we see that when the trunk reaches the maximum speed that the gorilla carries, the friction force is equal to the gorilla's tension

            fr = T

for a specific calculation we must assign values ​​to:

      μ = 0.25

      m = 100 kg

let's calculate

         T = 0.25 100 9.8

         T = 245 N

therefore for this case

         fr = 245 N

Explanation:

Temperature affects the amount of sugar that will be dissolved in a liquid. It is general knowledge in chemistry that solutes tend to dissolve in hot solvents compared to cold solvents.

Hence, there is a positive relationship between dissolution of sugar in a liquid and increase in temperature.

To test this hypothesis, the variables are temperature and amount of solute. The volume of solvent and type of solvent must be held constant.

Different amounts of solute are dissolved in the same volume of solvent and heated to a constant temperature and the extent of dissolution of the sugar is observed for each experimental unit.

A control experiment is also set up in which different amount of sugar is dissolved in the same volume of solvent as above without heating and the results are compared.

Answer:

See the answers below.

Explanation:

a)

The change in momentum can be calculated by means of the following equation.

[tex]P=m*v[/tex]

where:

P = momentum [kg*m/s]

m = mass = 45 [g] = 0.045 [kg]

v = velocity = 20 [m/s]

[tex]P=20*0.045\\P=0.9[kg*m/s][/tex]

b)

The change in momentum can also be calculated by means of the product of force by the duration time of the impact.

[tex]F*t=P\\F*0.006=0.9\\F=0.9/0.006\\F =150 [N][/tex]

Answer:

the horizontal velocity while it was falling is 22.1 m/s.

Explanation:

Given;

height of fall, h = 16 m

horizontal distance, x = 40 m

The time to travel 16 m is calculated as;

[tex]t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 16}{9.8} } \\\\t = 1.81 \ s[/tex]

The horizontal velocity is calculated as;

[tex]v_x = \frac{X}{t} \\\\v_x = \frac{40}{1.81} \\\\v_x = 22.1 \ m/s[/tex]

Therefore, the horizontal velocity while it was falling is 22.1 m/s.

The horizontal velocity while it was falling is

Horizontal velocity becomes important for objects moving in a horizontal direction. Generally, horizontal velocity is horizontal displacement divided by time, such as mph or m/s.

Therefore, from equation of motion

[tex]Time, t = \sqrt\frac{2h}{g}\\\\t = \sqrt\frac{2*16}{9.8}\\\\t = 1.81sec[/tex]

Therefore, the horizontal velocity, [tex]V_h[/tex]

[tex]V_h = \frac{x}{t}\\\\V_h = \frac{40}{1.81}\\\\V_h = 22.09 or 22.1m/s[/tex]

Answer:

The direction of the resultant force is approximately 189.462º.

The magnitude of the resultant force is approximately 1216.553 newtons.

Explanation:

Let consider postive the direction of motion of Daisy's foot and the upward direction (perpendicular to direction of motion). Friction ([tex]f[/tex]), measured in newtons, is directed against motion, whereas normal force from ground to the foot ([tex]N[/tex]), measured in newtons, is in the upward direction. Then, resulting direction must be greater than 180º but less than 270º with respect to the axis of the direction of motion, which is found by the following formula:

[tex]\theta = 270^{\circ}-\tan^{-1} \frac{N}{f}[/tex] (1)

Where [tex]\theta[/tex] is the direction of the resultant force, measured in sexagesimal degrees.

If we know that [tex]N = 1200\,N[/tex] and [tex]f = 200\,N[/tex], then the direction of the resultant force is:

[tex]\theta = 270^{\circ}-\tan^{-1} \frac{1200\,N}{200\,N}[/tex]

[tex]\theta \approx 189.462^{\circ}[/tex]

The direction of the resultant force is approximately 189.462º.

The magnitude of the resultant force ([tex]F[/tex]), measured in newtons, is determined by Pythagorean Theorem:

[tex]F = \sqrt{f^{2}+N^{2}}[/tex]

[tex]F =\sqrt{(200\,N)^{2}+(1200\,N)^{2}}[/tex]

[tex]F \approx 1216.553\,N[/tex]

The magnitude of the resultant force is approximately 1216.553 newtons.

Answer:

300 m/s

Explanation:

Step one:

Given data

Mass of players head m1= 5kg

The initial velocity of players head u1= 3.2m/s

mass of ball m2= 0.5kg

Initial velocity of ball= 5 m/s

Final velocity of player= 2.5 m/s

Required

The velocity of the ball after collision

Step two:

Applying the conservation of momentum formula for elastic collision

m1u1+m2u2= m1v1+m2v2

substitute

5*32+0.5*5= 5*2.5+0.5*v2

160+2.5= 12.5+0.5v2

collect like terms

162.5-12.5= 0.5v2

150= 0.5v2

divide both sides by 0.5

v2= 150/0.5

v2=300 m/s

The new velocity of the ball is 300 m/s

Answer:

2106 W

Explanation:

Given that

The coefficient of heat transfer, h = W/m².K

Area of cabin exposed to air, A = 9 m²

Initial ambient temperature, T1 = 33 °C

Final system temperature, T2 = 20 °C

To find the cooling rate needed, we use the formula

Q = h * A * ΔT

where, ΔT = T1 - T2

ΔT = 33 - 20

ΔT = 13 °C

Cooling rate, Q = 18 * 9 * 13

Cooling rate, Q = 2106 W

This means that the cooling rate needed is 2106 W

Explanation:

This question is incomplete, the complete question is;

The electric force due to a uniform external electric field causes a torque of magnitude 20.0 × 10⁻⁹ N⋅m on an electric dipole oriented at 30° from the direction of the external field. The dipole moment of the dipole is 7.5 × 10⁻¹² C⋅m.

What is the magnitude of the external electric field?

If the two particles that make up the dipole are 2.5 mm apart, what is the magnitude of the charge on each particle?

Answer:

- the magnitude of the external electric field is 5333.3 N/C

- the magnitude of the charge on each particle is 3.0 × 10⁻¹² C  ≈ 3 nC

Explanation:

Given that;

Torque = 20.0 × 10⁻⁹ N⋅m

dipole moment = 7.5 × 10⁻¹²

∅ = 30°

The moment T of restoring couple is;

T = PEsin∅

E = T/Psin∅

we substitute

E = 20.0 × 10⁻⁹ N⋅m / (7.5 × 10⁻¹²) sin(30°)

E = 20.0 × 10⁻⁹ / 3.75 × 10⁻¹²

E =  5333.3 N/C

Therefore, the magnitude of the external electric field is 5333.3 N/C

The dipole moment is given by the expression;

p = ql

q = p / l

given that l = 2.5 mm = 0.0025 m

we substitute

q = 7.5 × 10⁻¹² / 0.0025

q = 3.0 × 10⁻¹² C ≈ 3 nC

Therefore, the magnitude of the charge on each particle is 3.0 × 10⁻¹² C ≈ 3 nC

The anomalous expansion of water refers to the fact that water, unlike most substances, expands when it freezes. The density of water increases as temperature decreases but reaches a maximum at 4° C then begins to expand.

When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.

Answer:

Acceleration.

Explanation:

American football is one of the sports with the highest physical contact, along with boxing, mixed martial arts and rugby. Therefore, the risk of injury for players who play the sport is higher. However, many injuries in this sport have to do with blows to the head, where concussions occur that generate small neuronal short circuits due to the impact, which can cause fainting, amnesia and even vomiting.

This type of injury occurs due to the acceleration of the players when impacting their rival, which increases their strength (since it is known that the greater the acceleration the weight acquires a greater impact force).

Answer:

Acceleration causes the force of concussions for many professional football players.

Answer:

A. Gasoline

B. Apple juice

Explanation:

A homogeneous mixture can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture.

For instance, aqueous hydrogen chloride, HCl(aq) is a homogeneous mixture. The aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride. This ultimately implies that, aqueous hydrogen chloride HCl(aq) is a solution of hydrogen chloride in water and it is commonly referred to as Hydrochloric acid.

Hence, the two mixtures that are homogeneous are gasoline and apple juice.

Answer:

A. Gasoline

B. Apple juice

A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform.  The difference is that the composition of the substance is always the same. The amount of salt in the salt water can vary from one sample to another. All solutions would be considered homogeneous because the dissolved material is present in the same amount throughout the solution.

One characteristic of mixtures is that they can be separated into their components. Since each part of the mixture has not reacted with another part of the mixture, the identities of the different materials is unchanged.

Hence, the two mixtures that are homogeneous are gasoline and apple juice

Answer:

On Jupiter, the man would weigh  1.903 kN

Explanation:

Given that;

a mans weight is 720 N

on earth, g = 9.8 m/s²

so mass on earth will be;

m = F/g = 720 / 9.8 = 73.4693 kg

In Jupiter, g = 25.9 m/s²

so the man's weight in Jupiter will be;

F = mg

F = 73.4693 × 25.9

F = 1902.8549

F = 1.903 kN

Therefore, on Jupiter, the man would weigh  1.903 kN
