butalik [34]
<h2>Velocity at maximum height is zero.</h2><h2>Acceleration at maximum height is 9.81 m/s² downward.</h2><h2>Acceleration when it just hits the ground is 9.81 m/s² downward.</h2>

Explanation:

For a ball thrown vertically upward, the velocity at maximum height is zero.

Acceleration is a constant for a ball thrown vertically upward, its is acceleration due to gravity.

Acceleration at maximum height is 9.81 m/s² downward.

Acceleration when it just hits the ground is 9.81 m/s² downward.

Explain how the wave behave as the Frequency changes using the characteristic described in
Serggg [28]

Let's find the relationship

\\ \rm\Rrightarrow E=h\nu

\\ \rm\Rrightarrow \lambda=\dfrac{c}{\nu}

  • So if frequency increases Energy of the wave increases and wavelength decreases and vice-versa
