You throw a 50.0g blob of clay directly at the wall with an initial velocity of -5.00 m/s i. the clay sticks to the wall, and the collision takes about 20.0 ms (2.00 x 10^-2 s). a) what is the change in momentum for the blob of clay?

0.25 kg-m/s

Explanation:

Given

mass of blob

initial velocity

time of collision

we know Impulse is equal to change in momentum

initial momentum

Final momentum

as final velocity is zero

Impulse

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
