Answer:
New speed of the 22-kg block is 1.57 m/s
Explanation:
Mass of block
Mass of another block
Initial speed of the block
Initial speed of the another block
Initial speed of the another block
For conservation of momentum, we have
Substitute all the values and solving for final speed of the 22kg block is
new speed of the 22-kg block is 1.57 m/s
Couldnt write the answer so check picture
Answer:
Explanation:
As per Ampere's law the magnetic field at the surface of the wire is given as
here we have
so we will have
now again we use same value of current but wire with double the diameter
so the magnetic field at the surface is given as
so we have
