Answer:

The resulting speed of the ball is;

10 m/s

Explanation:

The given parameters are;

The amount of work done by the lever = 5.0 J

The mass of the ball on which the work is done, m = 0.10 kg

By the principle of conservation of energy, we have;

The work done by the lever = The kinetic energy. K.E., gained by the ball

The kinetic energy, K.E., is given by K.E. = 1/2·m·v²

Where, for the ball, we have;

m = The mass of the ball

v = The resulting speed of the ball

Therefore, by substituting the known values, we have;

The work done by the lever = 5.0 J = The kinetic energy. K.E., gained by the ball =  1/2 × m × v² =  1/2 × 0.10 kg × v²

∴ 5.0 J = 1/2 × 0.10 kg × v²

v² = 5.0 J/(1/2 × 0.10 kg) = 100 m²/s²

v = √(100 m²/s²) = 10 m/s

The resulting speed of the ball, v = 10 m/s.

False.

Explanation:

A good health can be defined as the state of well-being in which all of the components of an individual's health are in balance. These state of well-being comprises of six (6) important components and they are;

1. Physical: this is a measure of the state of an individual's body or the way the body functions. It is enhanced by eating right, working out or exercising, avoiding drugs and alcohol, maintaining a good body mass index etc.

2. Emotional: this deals with the state of an individual's mind being void of worries, negativity etc.

3. Social: this involves keeping a good relationship with friends, family and many others around.

4. Environmental: it deals with maintaining a hygienic surrounding, that is devoid of pollutants.

5. Mental or intellectual: avoiding unnecessary stress and anxiety while dealing or coping with the realities of life.

6. Spiritual: it encompasses belief systems, values, ideals, morality etc.

When an individual is able to balance all of these above mentioned components, then he or she is said to be healthy.

Hence, making good lifestyle choices will not and cannot prevent all diseases because some diseases are hereditary in nature i.e they can be transferred from a parent to their offspring or generation to another through genetics. Some examples of hereditary diseases are haemophilia, sickle-cell anaemia, thalassemia, cystic fibrosis, etc.

Answer:

The flow of energy from falling water to the steam is;

a) Mechanical → Mechanical → Electrical → Thermal → Thermal

Explanation:

1) Mechanical → Mechanical

The water in the pipe before it falls possesses potential energy which it converts into kinetic energy as it falls from height

2) Mechanical → Mechanical

The water falling from the pipe stream unto the turbine wheel transfers its kinetic (mechanical) energy due to its motion on to the turbine wheel to give the wheel rotational motion

3) Mechanical → Electrical

The kinetic (mechanical) energy from the rotating turbine wheel is converted into electrical energy in the electrical generator which transported through the electrical circuit

4) Electrical → Thermal

The electrical energy from the electric current is then converted into thermal energy as the current passes through the resistors in the heating filament

5) Thermal → Thermal

The heated filament transfers thermal energy to the the water in the beaker by conduction which raises the temperature of the water such that as the water acquires more thermal energy it turns into steam

Therefore, we have the flow of energy from the falling water to steam as follows;

1) Mechanical 2) Mechanical 3) Electrical 4) Thermal 5) Thermal

Answer:

Well its what makes a salad taste good.

Answer:

15 watt

Explanation:

Power is the rate at which work is done.

This means you divide the work done with the amount of time used to perform the work.

The formula for Power is : P = W/t  where;

W= work done in J = 45

t= time in seconds = 3 sec

P= 45/ 3 = 15 watt

because it is not a complete circuit

hope it helps! please mark me brainliest

thank you! have a good day ahead

if u follow me, I will follow u back

Answer:

Circuit A (answer C), does not allow current to flow, because there is no connection between the charge and ground (or positive and negative).

Answer:

the filling stops when the pressure of the pump equals the pressure of the interior air plus the pressure of the walls.

Explanation:

This exercise asks to describe the inflation situation of a spherical fultball.

Initially the balloon is deflated, therefore the internal pressure is equal to the pressure of the air outside, atmospheric pressure, when it begins to inflate the balloon with a pump this creates a pressure in the inlet valve and as it is greater than the pressure inside, the air enters it, this is repeated in each filling cycle, manual pump.

When the ball is full we have two forces, the one created by the external walls and the one aired by the pressure of the pump, these forces are directed towards the inside, but the air molecules exert a pressure towards the outside, which translates into a force. When these two forces are equal, the pump is no longer able to continue introducing air into the balloon.

Consequently the filling stops when the pressure of the pump equals the pressure of the interior air plus the pressure of the walls.

Answer:

   v = 72 km / h

Explanation:

The definition of average speed is the distance traveled between the time interval

          v = Δx / Δt

let's find the distance traveled

       x = 60 + 30

       x = 90 km

time spent, all time must be included, travel time and when stopped

       t = 0.45 + 0.15 + 0.5+ 0.15

       t = 1.25 h

we substitute in the initial equation

      v = 90 / 1.25

       v = 72 km / h

Answer:

Explanation:

It is the energy an object has on its virtue of mass.Because the energy acting on the object is working being done to keep that object in the position is it.

Answer:

r = 50[m]

Explanation:

Since the instrument has an operating or range radius, we must calculate this working distance or radius. We can determine the working area with the values that were given to us.

[tex]A=\frac{70W}{0.0089\frac{w}{m^{2} } } \\\\A=7865.16[m^{2} ][/tex]

Now using the area of the circle we can find the radius.

[tex]A=\pi *r^{2} \\7865.16=\pi *r^{2} \\\\r=\sqrt{\frac{7865.16}{\pi } } \\r=50[m][/tex]

So correct answer is "alpha radiation" .

Answer: 1350J

Explanation:

To solve this, we are going to use the formula for calculating potential difference which is:

Potential difference (V) = Work done (W) / Total charge (C)

Therefore,

9 volts = Work done / 150

Work done = 150 × 9 = 1350J

Answer:

1) Mass of Egg Chamber → 35 g = 35 g × 1 kg/(1000 g) = 0.035 kg

2) Average Mass of Grade A Egg       →    56.7 g = 0.056 kg

3) Calculated Mass

Drop Chamber + Egg → (35 + 56.7) g = 91.7 g = 91.7 g × 1 kg/(1000 g) = 0.0917 kg

4) Time of Drop → 1.5 seconds

5) Maximum Velocity of Drop Chamber (v = g·t) → v = 9.8 m/s² × 1.5 s = 14.7 m/s

6) Maximum Momentum of Drop Chamber

(P = m·v) (right before hitting the ground) → p = 0.0917 kg × 14.7 m/s = 1.34799 kg·m/s

7) Final End Momentum of Drop Chamber → After landing, velocity v = 0 m/s

(p = m·v after landing)   [tex]{}[/tex]                              ∴ p = m·v = m × 0 m/s = 0 kg·m/s

8) Impulse on Impact            →   [tex]{}[/tex]             (0 - 1.34799) kg·m/s = 1.34799 kg·m/s

(Δm·v = Final - Initial)

9) Force on Impact    [tex]{}[/tex]           →                 F·t = Δm·v = 1.34799 N·s

(F·t = Δm·v)
