Answer:
0 km/h
Explanation:
Relative speed is the speed of a moving body with respect to another.
When two bodies move in the same direction then the relative speed is calculated as difference of their speeds.
In this case;
The two cars have the same speed. The relative speed will be;
72 km/h -72 km/h = 0 km/h

Answer:
The new current in the wire is 6.3 A.
Explanation:
Given that,
Force in a straight wire, F = 0.023 N
Current in the wire, I = 2.5 A
If new force is, F' = 0.058 N, we need to find the new current.
We know that, magnetic force is given by :
It is clear that force is directly proportional to electric current. So, we can say:
I' is new current
So, the new current in the wire is 6.3 A. Hence, this is the required solution.

Answer:
Visible waves can be seen by people.
Explanation:
Electromagnetic waves comprises of different kind of waves. It consists of cosmic waves, x-rays waves, gamma waves, ultra violet waves, visible waves, infrared waves, microwaves. Among these waves, depending upon the wavelength of each kind of waves, it is visible and invisible to naked eyes. Thus, visible waves are the one which can be seen by people in naked eyes. As the wavelength of these waves are in comparable to the eye sight, so it can be seen by people.
