At the lowest point of its motion, kinetic energy is maximum and potential energy is minimum. This is where the velocity is a maximum. At the highest point of its motion, kinetic energy is minimum (i.e. zero) and potential energy is maximum.
Then, number of protons would be equal to number of electrons.
Answer:
Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less.
Explanation:
Astronomers can measure a star's<span> position once, and then again 6 months later and </span>calculate<span> the apparent change in position. The </span>star's<span> apparent motion is called stellar </span>parallax<span>. The </span>distance<span> d is measured in parsecs and the </span>parallax<span> angle p is measured in arc seconds.</span>
Answer:
69000 V
Explanation:
E = Electric field = 
d = Distance between plates = 2.3 cm
When we multiply the electric field strength and the distance between the plates of a capacitor we get the maximum voltage.
Maximum voltage is given by
The highest voltage the students can use is 69000 V
