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:
According to the travellers, Alpha Centauri is <em>c) very slightly less than 4 light-years</em>
<em></em>
Explanation:
For a stationary observer, Alpha Centauri is 4 light-years away but for an observer who is travelling close to the speed of light, Alpha Centauri is <em>very slightly less than 4 light-years. </em>The following expression explains why:
v = d / t
where
- v is the speed of the spaceship
- d is the distance
- t is the time
Therefore,
d = v × t
d = (0.999 c)(4 light-years)
d = 3.996 light-years
This distance is<em> very slightly less than 4 light-years. </em>
I think the best answer is option one. The first thing to focus on when creating a workout plan is <span>determining the frequency of the activity. It is important took look at how much time do you have to do things in order to manage your tasks daily and you can give enough time for each activity.</span>
Answer:
False
Explanation:
The second you let go its gonna release kinetic energy that's why it's potential
Force (N) = mass (kg) x velocity (m/s) / time (s)
