Answer:
Impulse will be 12 kgm/sec
So option (b) will be correct option
Explanation:
We have given mass of the baseball m = 0.15 kg
Ball speed before hit
Ball speed after hitting ( negative direction due to opposite direction )
We have to find the impulse
We know that impulse is equal; to the change in momentum
So change in momentum =
So option (b) will be correct option
Answer:
To determine how efficient that system is.
It becomes faster because there is less weight being pulled
Haha... no,
ferromagnetism is a substance with a high/natural susceptibility to magnetization. So those are your earth metals exhibiting unique magnetic behavior like iron, cobalt, and nickel.
Paramagnetism is when certain materials are weakly attracted by an external magnetic field, producing their own induced magnetic fields, aluminum is an example
Diamagnetism is when to magnetic things approach each other and there are repelling due to their electrons orbiting in opposite directions.
One of the forms of Ohm's Law says . . .
I = E / R
Current = (voltage) / (resistance)
so
Current = (100v) / (7.41Ω)
Current = 13.49 Amperes
