A 90 kilogram diver jumped from a cliff. If it takes 2.26 seconds for the diver to hit the water, how high is the cliff?
2 answers:
The height of the cliff will be 25.05 m. The height of the cliff is obtained by the Newton equation of motion.
<h3>What is height?</h3>The vertical distance between the object's top and bottom is defined as height. It is measured in centimeters, inches, meters, and other units.
The given data in the problem is;
Mass of diver(m)=90 kilogram
Time period(t)=2.26 sec
Initial velocity (u)=0 m/sec
The height attained by the cliff is;
Hence, the height of the cliff will be 25.05 m.

Answer:
Vr = 20 [km/h]
Explanation:
In order to solve this problem, we have to add the relative velocities. We must remember that velocity is a vector, therefore it has magnitude and direction. We will take the sea as the reference measurement level.
Let's take the direction of the ship as positive. Therefore the boy moves in the opposite direction (Negative) to the reference level (the sea).
Answer : The wavelength of photon is,
Explanation : Given,
Energy of photon =
Formula used :
As,
So,
where,
= frequency of photon
h = Planck's constant =
= wavelength of photon = ?
c = speed of light =
Now put all the given values in the above formula, we get:
Conversion used :
Therefore, the wavelength of photon is,
