mv'=(M+m)v

v'=d/t

v=x/t

m'=M/2

Md/2t=(M+M/2)x/t

Md/2=3Mx/2

d=3x=>x=d/3=6/3=2 m

A current carrying loop of width a and length b is placed near a current carrying wire. How does the net force on the loop compa
makvit [3.9K]

Answer/ Explanation

the loop has no force and the wires cancel each other but the wire on the loop has a force

The segment a get the same force for both but in the loop segment b get an opposite force so the net force on the loop is smaller

The loop wire has forces that all cancel out while the other straight wire doesn't.

a car moving with a speed of 10 metre per second is accelerator at the rate of 2 metre per second square find its velocity after
STatiana [176]

a = ( v(2) - v(1) ) ÷ ( t(2) - t(1) )

2 = ( v(2) - 10 ) ÷ ( 6 - 0 )

2 × 6 = v(2) - 10

v(2) = 12 + 10

v(2) = 22 m/s

Conclusion of galileo feather and coin experiment
Novosadov [1.4K]

Answer:

This experiment lets you repeat Galileo's experiment in a vacuum. The free fall of a coin and feather are compared, first in a tube full of air and then in a vacuum. With air resistance, the feathers fall more slowly. In a vacuum, the objects fall at the same rate independent of their respective masses.

A charge of +0.001 C is 1 m to your right and another charge of +1000 C is 1 m to your left. You are holding a charge of −1 C. W
almond37 [142]

Answer:

C and D

Explanation:

Charge on right = +0.001 C

Charge on left = 1000 C

Charge held in between = -1C

Ratio between right and left charge:

=\frac{1000}{.001}\\\\=1\times 10^6

Which shows charge on left exerts 1,000,000 times more force then charge on right

Charge on left is 1000 times greater in magnitude than charge held between and charge held between is 1000 times greater in magnitude than charge on right. So the magnitude of the force on the charge you are holding would be the same if it were +1 C instead of −1 C.
