Answer:

Speed of cart's might be less than the high speed after 5 seconds.

Explanation:

Given that,

A fan cart with the fan set to high rolled across the floor.

Let the speed of fan cart with set to high is x\ cm per second.

The fan supplies a force to the cart. If a lower fan speed were used, less force would be applied. This would cause a slower change in the cart's speed. So, the cart would be rolling more slowly than x\ cm per second after 5 seconds. The speed of cart's might be less than x\ cm per second.

Force is needed

A. for a moving object to keep moving at the same speed and direction

B. for a moving object to change its speed

C. for a motionless object to remain still

D. to prevent a moving object from turning

Hence,

Speed of cart's might be less than the high speed after 5 seconds.

A force of 500 N is used to slide a box across a smooth surface; the box moved 5 m in 1.2 seconds. What power is used?
Katen [24]
F = 500N
S = 5m
T = 1.2s
----------------------------------
P = ?

We can use formula P = F * V, just because it was a smooth slide we can assume that average speed was V = S/T = 5 / 1.2 = 50/12

So the final answer would be:

P = F * V = 500 * 50/12

Are you sure those are correct numbers? The answer don't look nice :D

Answer:

Explanation:

3. The word circuit means "go around", therefore a circuit is a pathway or closed path around which electricity (or water) flows.

4. Electrons flowing through a wire can be compared to water flowing through a hose. Once the flow of electrons or water is going, work, is performed.

5. You would get shocked in a bumper car by touching the floor and the ceiling at the same time. This means you are completing the circuit allowing electricity to flow.

6. Electricity from a wall outlet has enough energy to stop your heart.

7. Electricity is the flow of electrons, because electrons move or jump from atom to atom.

8. Materials that allow electrons to move easily from atom to atom are called conductors.

9. Materials that do not allow electrons to flow easily are called insulators.

10. Semi- conductors are materials that are somewhere in between .

11. Voltage is the force or pressure of electricity and is compared to the amount of water pressure in a hose.

12. Current (amps ) is the amount of electricity and is compared to the amount of water in a hose .

13. Watts (power) is the term for work performed by electricity.

Heat gained minus work fine is equal to what?
Zina [86]

Heat transferred - Work done = Internal Energy

Explanation:

  • If there is more heat transfer than the work done, the energy difference is called internal energy
  • The first law of thermodynamics equation is given as ΔU=Q−W where, ΔU = Internal energy; Q = Heat transfer; W = Work done
  • Heat = transfer of thermal energy between two bodies at different temperatures
  • Work = force used to transfer energy between a system and its surroundings
  • The First Law of Thermodynamics states - energy can be converted from one form to another with the interaction of heat, work and internal energy
  • Energy cannot be created nor destroyed
