Answer: 
Explanation:
Given
Current in the first wire 
Current in the second wire 
wires are 
apart
Force per unit length between the current-carrying wires is
Force exerted by the wires is the same
Put the values
This force will be repulsive in nature as the current is flowing opposite
Answer:electrical potential
Hi there!
Recall that:
Change in momentum = mass × change in velocity
Or:
Δp = mΔv = m(vf - vi)
Plug in the given values. We can assign east to be positive and west to be negative in this instance (Velocity is a vector with direction).
Thus:
Δp = (1)(-21 - 10) = -31 kgm/s OR 31 kgm/s WEST.
The correct answer is B.
Change in momentum is EQUIVALENT to the quantity of IMPULSE.
The correct answer is H.
Scientific evidence supports a new idea
F=ma. So if you have the Force and the Acceleration you can find the mass. m=F/a. So the mass is 25kg
