Answer:
Acceleration of the ship,
Explanation:
It is given that,
Mass of both ships,
Distance between two ships, d = 110 m
The gravitational force between two ships is given by :
F = 8.38 N
Let a is the acceleration. Now, using second law of motion as :
So, the acceleration of either ship due to the gravitational attraction of the other is . Hence, this is the required solution.
Answer:
The observer detects light of wavelength is 115 nm.
(b) is correct option
Explanation:
Given that,
Wavelength of source = 500 nm
Velocity = 0.90 c
We need to calculate the wavelength of observer
Using Doppler effect
Where,
Hence, The observer detects light of wavelength is 115 nm.
They are attractive
They don’t depend on charge
