Displacement will be 15 too because
It falls from 0 till 15 meters
Answer:
b the answer is b
Explanation:
b is the awnser because it cools after the heat on the water witch lets the steam out
Answer: C
high; large
Explanation:
The wave energy is related to its amplitude and frequency.
The wave energy is proportional to the amplitude of the wave. So, wave with the most energy will have high amplitude.
Also, frequency is related to wave energy. The larger the frequency, the more the energy of the wave.
Therefore, The waves with the MOST energy have high amplitudes and large
frequencies.
Answer:

Explanation:
Given:
density, 
diameter of the pipe, 
pressure difference, 
In case of pitot tube, the velocity is given by:



Now we know that volumetric flow rate is given as:

where :
a= cross sectional area of the pipe
v= velocity of flow


Answer:
Time and velocity
Explanation:
The time taken for the velocity to double is very important to find the amount of acceleration the car acquires.
Acceleration is the rate of change of velocity with time.
Acceleration =
v is the initial velocity
u is the final velocity
t is the time taken
So, the velocity and time is needed to calculate the value of the acceleration the car undergoes.
