Answer:
Explanation:
Given
Diver is at a depth of inside the water
As we go down pressure increases due to the weight of liquid column above us
Pressure difference is given by
Where =density of liquid
h=depth
g=acceleration due to gravity
So external-internal pressure difference is
Explanation:
It is given that,
The acceleration of the toboggan,
Initial speed of the toboggan, u = 0
We need to find the distance covered by the toboggan. Using the second equation of motion as :
At t = 1 s
At t = 2 s
At t = 3 s
Hence, this is the required solution.
C) is correct
series circuit - in the same path : current flow on one path so they are equal on each component and equal to the source's. voltage on each components may be different.
parallel circuit - between same nodes : voltage of the components are equal and equal to the source's. current on each components may be different.
It produces more infrared, which is a low-frequency invisible light.
