If a negative object is used to charge a neutral object, then both objects become charged negatively if this answer is wrong I'm sorry.
To solve the problem, we can use Ohm's law, which states that
where
V is the voltage
I is the intensity of current
R is the resistance
Using the data of our problem, I=4 A and
, we find the voltage:
The amplitude cannot be determined.
Explanation:
Given the parameters in the problem statement, it is impossible to determine the amplitude of the wave.
The velocity of the wave cannot be determined from the information of the velocity and period of the wave.
Velocity of the wave;
Velocity = Frequency x Wavelength
- The amplitude of a wave is the vertical displacement of a wave from rest.
- Amplitude of a wave is not related to velocity of a wave.

This is true. let me know if im wrong.
To solve this problem we will apply the concepts related to the Doppler Effect. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other.
Mathematically it can be described as
Where,
v = Speed of sound
f' = Reflected frequency
f = Emitted Frequency
= Speed of the object
Assuming that the speed of the medium is the speed of sound of 343m / s, we will then have that:
