Answer:

y = 165.8 m

Explanation:

This is an exercise in kinematics that we must solve in parts,

Let's start with the final part where we have more data, the final velocity of the student and jet is zero, the upward acceleration is

          a = 4g = 4 9.8 = 39.2 m /s²

Let's find the initial velocity and the height

         v² = v₂² + 2 a y

         0 = v₂² + 2 ay

         2ay = - v₂²

          v₂² = 2a y

Let's write the equation for the first part

student

          v₂² = v₀² - 2 g (y₀ -y)

in this case the student jumps v₀ = 0

          v₂² = 2 g (y₀ -y)

the total height is y₀ = 829 m

let's solve the system of equations by equating

          2ay = 2 g (y₀ -y)

           2a y = 2 g y₀ - 2g y

          2 y ( g + a) = 2 g y₀

          y = yo   g/(g +a)

          a= 4 g

         y = yo 1/5

calculate

         y = 829 /5

         y = 165.8 m

Answer:

a) 1.75 m

b) 5 L

c) 5.5 g

d) 3.5 L

Explanation:

a) cm -> m

1 m = 100 cm, so,

1 cm = 1/100 m

175 cm = 175/100 m

175 cm = 1.75 m

b) mL -> L

1 L = 1000 mL, so

1 mL = 1/1000 L

5000 mL = 5000/1000 L

5000 mL = 5 L

c) kg -> g

1 g = 1/1000 kg, so

1 kg = 1000 g

0.0055 kg = 0.0055 * 1000 g

0.0055 kg = 5.5 g

d) cm³ -> L

1 L = 1000 cm³, so

1 cm³ = 1/1000 L

3500 cm³ = 3500/1000 L

3500 cm³ = 3.5 L

therefore, we can conclude that 175 cm is 1.75 m, 5000 mL is 5 L, 0.0055 kg is 5.5g and 3500 cm³ is 3.5 L

Answer:

The magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force. ( ¹/₄ F)

Explanation:

The electrostatic force between two charges is given by Coulomb's law;

[tex]F = \frac{kQ_1Q_2}{r^2}[/tex]

where;

Q₁ and Q₂ are the magnitude of the charges

r is the distance between the charges

k is Coulomb's constant

Since the charges are identical;

Q₁ = Q

Q₂ = Q

the electrostatic force experienced by each charge is given by;

[tex]F = \frac{kQ^2}{r^2}[/tex]

When each of the spheres has lost half of its initial charge;

Q₁ = Q/2

Q₂ = Q/2

[tex]F_2 = \frac{k(Q/2)(Q/2)}{r^2}\\\\ F_2 = \frac{k(Q)(Q)}{4r^2}\\\\F_2 = \frac{1}{4} (\frac{kQ^2}{r^2} )\\\\F_2 = \frac{1}{4} (F)[/tex]

Therefore, the magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force.

56.8 m = v₀ (5.8 s) + ½ (-9.8 m/s²) (5.8 s)²

v₀ ≈ 38.2 m/s

Answer:

C. It gains one or more electrons from another atom to become negatively charged.

Explanation: When it gains electrons it becomes negatively charged and is called an anion. When it loses electron(s) it becomes positively charged and is called a cation.

Hope this helps

Plz mark brainleist

An atom becomes an anion when it gains one or more electrons from another atom, resulting in a net negative charge. This process occurs through the formation of chemical bonds, typically in ionic compounds.

An atom's position in the periodic table affects how likely it is to gain electrons. Atoms in nonmetals and other elements on the right side of the periodic table have a stronger attraction for electrons and are more prone to undergo anion formation.

The extra electrons fill the highest energy level, creating a stable arrangement of electrons like that of a noble gas. Anions contribute to the overall charge balance of compounds and are crucial in a number of chemical processes.

Explanation:

The order of magnitude is a very useful unit for when you do not have a precision in the measurement, the way to find it is to take the number to scientific notation and then change the whole part to 101 if it is greater than or equal to five or 10 or less than five

A) take my age to seconds

for example if I am 25 years old.

I take the years to seconds

       age = 20 years (365 day / year) (24 h / 1 day) (3600 s / 1h)

      age = 630720000 s

we carry scientific notation

      age = 6.3072 10⁸ s

as the integer greater than five we change it by 10¹

      age = 10⁹s

The correct answer is 3

B) The number of beats per minute approximately 80 beats in a month we have

    # beats = 80 beats /min (60min / 1h) (24 h / 1 day) (30 day / 1 month)

    # _beats = 3456000 beats / month

   #_beats = 3,456 10⁶ beats / month

as the integer is less than five we change it by 10⁰

  #_beats = 10⁶

the correct answer is 3

C) the number of heartbeats in life

suppose a life expectancy of 80 years

    #_beats_total = 80 pulse /min (60min / 1h) (24 h / 1day) (365 day / year) 80 year

    #_total_beats = 3 363 840 000

    #_beats_total = 3.36384 10⁹

as the integer is less than five we change it by 10⁰

    #_beats_total = 10⁹

The sum of 8 and twice a number is : 8 + 2 n

Answer:

11 m/s south

Explanation:

The velocity of the passenger relative to the river bank is equal to the velocity of the passenger relative to the ferry, plus the velocity of the ferry relative to the river, plus the velocity of the river relative to the river bank.

v_passenger,bank = v_passenger,ferry + v_ferry,river + v_river,bank

If we take north to be positive and south to be negative:

v = 1.0 m/s + (-10 m/s) + (-2 m/s)

v = -11 m/s

v = 11 m/s south

Answer:

0.779m/s

Explanation:

A woman on a bridge 93.7m high sights a raft floating at a constant speed

She drops a stone from rest in an attempt to hit the raft

The stone is released when the raft had 4.94m to travel before passing under the bridge

The stone hits the water 1.53 m in front of the raft

The first step is to calculate the distance

= 4.94 m-1.53 m

= 3.41m

The time can be calculated as follows

= √2(93.7)/9.8

= √187.4/9.8

= √19.12244

= 4.373 secs

Therefore the speed of the raft can be calculated as follows

Speed= 3.41/4.373

= 0.779m/s

Hence the speed of the raft is 0.779m/s

Explanation:

The equation for accleration is a= ▲v/▲t With a final velocity of 0 m/s minus the initial 73 m/s, at an acceleration of 9.8 m/s^2, the ball would take 7.45 seconds to hit the ground.

Answer:

42.9 m.

Explanation:

The following data were obtained from the question:

Initial velocity (v₀) = 29 m/s

Acceleration due to gravity (g) = 9.8m/s²

Maximum height (h) =.?

The maximum height reached can be obtained by using the following formula:

H = v₀² /2g

Where:

H is the maximum height reached.

v₀ is the initial velocity.

g is the acceleration due to gravity.

H = v₀² /2g

H = (29)² / (2 × 9.8)

H = 841 / 19.6

H = 42.9 m

Therefore, the maximum height reached by the arrow is 42.9 m

Answer:

The steam will start to condense at 6.6 mm into the pipe

Explanation:

The volume flow rate =π×(50/1000)²/4×10 = 0.0196 m³/s

The specific volume of the steam = 1.769 m³/kg

Therefore;

The mass flow rate = 0.0196/1.769 = 0.011099  kg/s

The resistance of the insulation material = ln(0.075/0.05)/(2×π×0.075) = 0.860 K/W

The resistance of the outside film of the insulator = 1/(15×2×π×0.075×1) = 0.14147 K/W

The total resistance = 0.14147 + 0.860 = 1.00147 K/W

1/(UA) = 1.00147 K/W

A = 2×π×0.05×1

1/U = 0.3146

U = 3.178 W/m² K

We have;

T(x) = T₀ + (Tin - T₀) exp(-UπDx/mcp)

Therefore, when T(x) = 100°C, we have;

100 = 20 + (120 - 20)exp(-3.178×π×0.05x/(0.011099 × 1.33))

Solving, we get

x = 6.597× 10⁻³ m ≈ 6.6 mm

Therefore, the steam will start to condense at 10 mm into the pipe.

Answer:

(a) the student's apparent weight during the lift is 914.2 N

(b) the student's apparent weight during the fall is 0

Explanation:

Given;

student weight, W = 700 N

upward acceleration, a = 3 m/s²

Apply Newton's second law of motion;

The reading on the scale = student's apparent weight

(a) during the lift

R = W + F

R = W + ma

where;

m is mass of the student = 700 / 9.8  =  71.4 kg

R = 700 + 71.4(3)

R = 700 + 214.2 N

R = 914.2 N

(b) during the fall

R = W - ma

R = mg - ma

R = m(g-a)

here,  a = g

R = m(g - g)

R = m(0)

R = 0

Thus, during the free fall the student experiences weightlessness or zero apparent weight.

Answer:

the only effect it has is to create more induced charge at the closest points, but the net face remains zero, so it has no effect on the flow.

Explanation:

We can answer this exercise using Gauss's law

      Ф = ∫ e . dA = [tex]q_{int}[/tex] / ε₀

field flow is directly proportionate to the charge found inside it, therefore if we place a Gaussian surface outside the plastic spherical shell.  the flow must be zero since the charge of the sphere is equal  induced in the shell, for which the net charge is zero. we see with this analysis that this shell meets the requirement to block the elective field

From the same Gaussian law it follows that if the sphere is not in the center, the only effect it has is to create more induced charge at the closest points, but the net face remains zero, so it has no effect on the flow , so no matter where the sphere is, the total induced charge is always equal to the charge on the sphere.

Answer:

This question is an example of Boyle's gas law which states that the pressure of a given mass of a gas is inversely proportional to its volume at a constant temperature. The formula for this gas law is:

P1·V1 = P2·V2

P1 = initial pressure = 1.7 atm

V1 = initial volume = 4.25 L

P2 = final pressure = 2.4 atm

V2 = final volume = ?

Rearrange the formula to isolate V2. Substitute the known data and solve.

V2 = P1·V1/P2

V2 = 1.7 atm·4.25 L/2.4 atm = 3.0 L to two significant figures

The new volume will be ~3.0 L.
