Answer:
shift the wavelength of spectral lines
Explanation:
The Doppler effect is commonly used in the field of astronomy to study the motion of astronomical objects such as a star, planets, and distant galaxies. This results in the changing of wavelength and shifting of the spectral lines, due to the relative and continuous motion of the receiver and the source. This is known as the red-shifting, where the lights in the spectrum move towards the highest wavelength, i.e towards the red light. This Doppler effect signifies that the distance between the distant galaxies and earth increases with the increasing recessional velocity.
Answer:
Explanation:
Read forces directly from the graph.
Read displacements directly from the graph.
Use the area under the graph to find the work done by the force. This is equal to the kinetic or potential energy the object gains due to the application of the force.
Answer:
The mass of the cable is 4.94 kg
Explanation:
It is given that,
Mass of the block, m = 20 kg
Force applied to the cable, F = 110 N
Speed of the block, v = 4.2 m/s
Distance, d = 2 m
Let a is the acceleration of the block. It can be calculated using the third equation of motion as :
Let m' is the mass of the cable. It can be calculated using the second law of motion as :
m = 4.94 kg
So, the mass of the cable is 4.94 kg. Hence, this is the required solution.
It would swim 30*15 metres, which is 450 metres.
