Answer:
B type ii supernova is the right answer
Answer:
Decrease
Explanation:
If you crawl to the rim the rotational speed will decrease. The law of conservation of angular momentum supports this answer. And it states that :
"When the net external torque acting on a system about a given axis is. zero , the total angular momentum of the system about that axis remains constant."
Answer: 100 N
Explanation: Taking into account the second Newton Law the total force applied to any system is equal to the mass *acceleration.In this case the crate moves at constant speed so the accelaration is zero. In order to satisfy this fact, the friction force must be equal the applied force of 100 N .
Answer:
62.7 VA
Explanation:
The apparent power (power supplied by the source) of an AC circuit is determined by
The impedance(Z) depends on the frequency, but in this case it is given to us that it is 102 ohms at this frequency.
So:
