Answer:
c. Induced voltage.
Explanation:
Faraday's law says

or in words,
<em>"A changing magnetic flux induces an emf (potential difference) in a coil of wire "</em>
This potential difference is induced, and therefore, we can also call it "induced voltage"; Hence, from the choices given, choice C stands correct.
<em>P.S: Another tempting choice is d; however, it is incorrect since induced emf is NOT an electrostatic force.</em>
The tiny space invader and the new space station will have equal orbital speed.
<h3>The orbital speed of satellite </h3>
The orbital speed of satellite on Earth surface is given as;

where;
- V is the orbital speed
- G is universal gravitation
- M is mass of the Earth
- r is the radius of the circular path
Since the two objects are at the same height from Earth's surface, the distance from the central point (r) will be the same. Thus, the two objects will have equal orbital speed.

Answer:443.1 s
Explanation:
Given
Engine of a locomotive exerts a force of 
Mass of train
Final speed (v)
F=ma
so 

and acceleration is
