Answer:
LONGITUDINAL WAVE
Explanation:
As we know that there are two type of propagation of wave
1) Transverse wave :
in transverse nature of waves the energy is propagated into the medium in perpendicular to the wave propagation.
So here in transverse waves the medium molecules will start oscillating in perpendicular direction
2) Longitudinal wave
Here in this type of wave the medium molecules will start oscillating in the direction of propagation of waves. So here the medium molecules will oscillate in the direction parallel to the wave propagation
so correct answer is
Longitudinal waves
You are observing the boiling point
Answer:
Work done is 882000joule.
power is 29400watt.
Explanation:
given,
Mass(m)=500kg
Acceleration due to gravity(g)=9.8m/s²
Height(h)=6m
Time taken(t)=30s
Workdone=?
Power=?
now,
workdone=force*displaxement
= m*g*h
=500*9.8*6
=8,82,000joule
so, the work done by the man is 8,82,000joule.
then,
power=workdone/time taken
=8,82,000/30
=29,400watt
so, the required power to lift a load is 29,400watt.
Answer:
there can be acceleration
Explanation:
because of the friction. If the friction and applied force is nowhere then it will not move, but if it has a friction it will move but not in the same direction it can only move slightly or really move. based on me only
Answer:
The statement is not correct.
Reason:
If two objects have the same mass, their respective densities determine their volumes.
By definition,
density = mass/volume.
or volume = mass/density.
Therefore if two objects have the same mass, the mode dense object (with higher density) will occupy less volume than the other object.
