Answer:
B.) by interfering with sound waves
Explanation:
As we know that the interference of sound waves is of two types
1). constructive interference
2). destructive interference
now we know that constructive interference means the resultant intensity will be more than the intensity of interfering waves as here two waves are in same phase.
In destructive interference the resultant of two waves is given by the minimum resultant of the intensity as here the phase of two waves are opposite to each other.
So we will say that
here in case of noise cancelling headphones we know that the phase of noise is always made in opposite phase with the sound which is used to cancelled the noise.
This will reduce the noise and we will get a clear sound
Answer:
Fe = 25.67 N
Fg = 2.0734 x 10^-35 N
Explanation:
r = 3 x 10^-15 m
G = 6.67 x 10^-11 Nm^2/kg^2
Mp = 1.6726231 x 10^-27 kg
Qp = 1.6021 x 10^-19 C
K = 9 x 10^9 Nm^2/C^2
The formula for the electrical force between the two protons is given by
Fe = 25.67 N
The formula for the gravitational force between the two protons is given by
Fg = 2.0734 x 10^-35 N
