Answer:
V = 0
Explanation:
To find the potential at the middle of the two charges with opposite signs, you use the following formula:
(1)
where you have used the fact that the charges are the same and the distances are the same.
The electric potential is zero at the point in the middle of the two charges
Answer:
A. Another form of energy is nuclear energy. ... The guitar produces sound energy when the guitarist plucks the strings.
B. The organ that we use to sense sound energy is the ear. ... Together, they gather sound waves, amplify the waves, and change their kinetic energy to electrical signals. The electrical signals travel to the brain, which interprets them as the sounds we hear.
Answer:
(a) Frequency will be equal to
(b) Wavelength will be equal to
Explanation:
Velocity of light
(A) We have given wavelength of light
We have to find frequency corresponding to this wavelength
We know that velocity of light is equal to
(b) We have given frequency of vibration
We have to find wavelength corresponding to this frequency
We know that velocity of light is equal to
Answer:
S = V0 t + 1/2 a t^2
S = 5 m/s * 300 s + 1/2 * 1.2 m/s * (300 s^2)
S = 1500 m + .6 * 90000 m = 55,500 m
Check: V0 = 5 m/s
V2 = V0 + a t = 5 + 1.2 * 300 = 365 m/s
Vav = (V1 + V2) / 2 = (5 + 365) / 2 = 185 m/s (note uniform motion)
S = 185 * 300 = 55,500 m
We calculated V2 above at 365 m/s the speed after 300 sec
