a)
b)
Explanation:
From the question we are told that:
Distance between wires 
Wire 1 current 
Wire 2 current 
a)
Generally the equation for Force on 
due to 
is mathematically given by
Where
B_2=Magnetic field current by
Therefore
b)
Generally the equation for Force on due to 
is mathematically given by
Where
B_1=Magnetic field current by
Therefore
Answer:
Explanation:
scientific notation for 724,000,000,000 is
7.24*10^11
B. The number of field lines on the source charge.
Momentum would be the same before and after the collision
Before the collision:
Momentum of the single cart: 1 * 0.50 = 0.50
After the collision
velocity = 0.25m / s
1 * 0.25 + 1 * 0.25 =
0.25 * (1 + 1) =
0.25 * 2 =
0.50
Now new momentum will be 0.5
answer
the same before and after the collision
