Answer:
the magnitude of momentum is √2≈ b
Explanation:
hope that helped
The answer is 10 i think so
Answer:
1500N
Explanation:
Normal force = mg - F sin theta
constant velocity means acceleration = 0
F= ma = 150× 0 = 0N
thus;
normal force = mg = 150 × 10 = 1500N
Answer:
Total angular displacement will be 19.998 radian
Explanation:
It is given that the washer starts from the rest and reach reach the speed of 2 rev/sec in 11 sec
So initial angular velocity 
And final angular velocity 
Time t = 11 sec
So angular acceleration 
So angular displacement in this 11 sec


Now the washer slows down and stops in 9 sec
So final angular velocity = 0 rad/sec
So angular acceleration 
So angular displacement 
So total displacement in 20 sec =
Higher-level consumers get the most energy from food they eat.
An example is a lion eating a zebra. The zebra has more energy than a handful of grass, which has almost none to offer.
