Answer:
Explanation:
When an object strikes the ground, the potential energy of the rock gets converted to the kinetic energy.
A rock is dropped from a distance above the surface of the earth and is observed to have kinetic energy when it hits the ground.
For another rock, It is dropped from twice the height above the earth’s surface and has kinetic energy when it hits.
For the first rock, ..............(1)
For the second rock, ..............(2)
Dividing equation (2) by (1) we get :
Hence, this is the required solution.
Answer:
The average gauge pressure inside the vein is 110270.58 Pa
Explanation:
This question can be solved using the Bernoulli's Equation. First, in order to determine the outlet pressure of the needle, we need to find the total pressure exerted by the atmosphere and the fluid.
Then, we have to find the fluid's outlet velocity with the transversal area of the needle, as follows:
As we have all the information, we can complete the Bernoulli's expression and solve to find the outlet pressure as follows:
D is the answer and also I love u
The answer will be Amplitude.
I think the answer may be D- mechanical
