Answer:
The percentage change in frequency is 10%.
Explanation:
Given that,
Amplitude decreases by 1/10 per second.
Resonance = 10 Hz
We need to calculate the change in frequency
Using formula of change in frequency
Put the value into the formula
We need to calculate the resonant frequency
Using formula of resonant frequency
Put the value into the formula
We need to calculate the percentage change in frequency
Using formula of percentage change in frequency
Hence, The percentage change in frequency is 10%.
The answer is c for that question
Point C. at this point, which is the highest point, all of the ball’s energy is gravitational potential energy.
The spacing between the fringes does not depend on the width of the slit.
The light intensity produced by the slits increases with increased width of the slit. The screen thus develops brighter fringes as the slit width increases.
On the screen, coloured fringes will be created if the white light replaces monochromatic light.
<h3>What is diffraction?</h3>
Diffraction is the breaking up of an electromagnetic wave as it passes a geometric structure (e.g. a slit), followed by reconstruction of the wave by interference. Diffraction occurs for all types of waves, including sound waves.

Im not really sure about my answer but im giving you a clue about magnetic fields..
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
