I had a different quiz, different question, same answer:
Which of these contributes to the creation of Milankovitch cycles?
B:Changes in Earth's axial tilt
The velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.
The velocity of the stone at the given displacement is calculated as follows;
K.E = ΔP.E
¹/₂mv² = mgh
v = √2gΔh
v = √[2(9.8)(7.7 - 5.25)]
v = 6.93 m/s
Thus, the velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.

Explanation:
Answer:
Visible light is an example of electromagnetic waves.
Explanation:
Visible light is an example of electromagnetic waves. The visible light are the range in which the light is visible to the human eye. The wavelength of visible light varies from 400 nm to 700 nm.
The visible region consists of following light namely,
1. Violet : 380–450 nm
2. Blue : 450–485 nm
3. Cyan : 485–500 nm
4. Green : 500–565 nm
5. Yellow : 565–590 nm
6. Orange : 590–625 nm
7. Red : 625–740 nm
Hence, the visible light is an example of electromagnetic wave.
