b. False
The answer would be, B-False
Answer:
14178 N
Explanation:
5560 Kg * 2.55m/s^2 = 14178 Newtons (Kg*m/s^2)
Answer:
6.17 m
Explanation:
speed, v = 11 m/s
Let the mas is m.
As according to the question
Potential energy = kinetic energy
m x g x h = 0.5 m v²
where, h is the height raised.
9.8 x h = 0.5 x 11 x 11
h = 6.17 m
Thus, the height raised is 6.17 m .
Answer: True
Explanation: A sonographer can adjust the duration of an acoustic pulse because it depends on the pulse's propagation speed.
