Assuming constant acceleration, the distance travelled in the first 4.5s is:
0.5*5.0*4.5 = 11.25m
The distance travelled in the next 4.5s is:
5.0*4.5 = 22.5m
The total distance travelled is:
11.25 + 22.5 = 33.75m
The true statements about generators would be :
They convert motion energy to electric energy
They use the relative motion of a magnet and a coil of wire.
Explanation:
Generators use the energy of the rotating coil in relative motion with magnets to induce a current within the wire. Generators are devices that convert energy into a voltage by the relative motion of the magnet and a coil that changes flux.
Answer:
The rate at which the energy of a system is transformed
Explanation:
Power is the rate at which energy of a system is transformed or the rate at which work is done. It is defined by Power = Workdone/time taken
Its unit is the Watt denoted by the letter W.
For example, assuming a work of 200 J is done in 10 s, then Power, P equals
P = workdone/time taken = 200 J/10 s = 20 J/s = 20 W
The question is asking to choose among the following choices that could complete the question about the inertia, base on my research and further investigation, the possible answer would be letter B. Gravity. I hope you are satisfied with my answer and feel free to ask for more
Answer:
Part a)
Part b)
Part c)
Part d)
Part e)
Part f)
Explanation:
Part a)
As we know that the maximum angle deflected by the pendulum is
so the maximum height reached by the pendulum is given as
so we will have
now gravitational potential energy of the pendulum is given as
Part b)
As we know that there is no energy loss while moving upwards after being stuck
so here we can use mechanical energy conservation law
so we have
Part c)
now by momentum conservation we can say
Part d)
Work done by the bullet is equal to the change in kinetic energy of the system
so we have
Part e)
recoil speed of the gun can be calculated by momentum conservation
so we will have
Part f)
Total energy released in the process of shooting of gun
