Answer:
volume of substance of weight of mercury is 13593 kilograms
Answer:
speed = distance/time
Explanation:
speed = 150/30
speed =5m/s
you were running fast .....5m/s is a good speed
Answer:1384 Hz
Explanation:
Given
wavelength
=0.25 m
Temperature T
at 
velocity of sound is 346 m/s
and we know
f=1384 Hz
Momentum is related to mass. In fact, it's directly proportional to mass.
Answer:
0 Newton
Explanation:
If the velocity becomes constant the acceleration will be zero and the net force will be zero because:
force = mass x acceleration
Since acceleration is 0:
force = mass x 0
force = 0
