Answer:
The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by <u>Ampere</u>
Explanation:
Two current carrying wires exert force on each other. This was discovered by Ampere. It is also known as Ampere's force law.
A current carrying wire produces magnetic field around it. Another current carrying wire kept nearby experiences magnetic force by the first one.
The force is given by:
where I₁ and I₂ are the currents in the two wires and r is the distance between them.
The force may be attractive or repulsive depending upon the direction of current flowing in the two wires.

Answer:
Fc = 19.2 N
Explanation:
In this case, the force of the Honda over the rock, is a centripetal force. Then, you have:
m: mass of the rock = 600g = 0.6 kg
v: tangential velocity of the Honda = 4m/s
r: radius of the Honda = 50cm = 0.5m
You replace the values of m, r and v in the equation for Fc:
hence, the force has a magnitude of 19.2 N
If the rock would have more mass the centripetal force would be higher
Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time
Put all the values,
So, 0.036 C of charge moves during this time.
