Answer:
The velocity of the 4.00 kg object after the collision is 12 m/s.
Explanation:
Given that,
Mass of object
Velocity of object
Mass of another object
Velocity of another object
We need to calculate the relative velocity
The relative velocity is 8 m/s in west before collision.
We know that,
In one dimensional elastic collision, the relative velocity before collision equals after collision but with opposite sign.
So, The relative velocity after collision must be 8 m/s in east.
So, The object of 6.00 kg is going 20 m/s and the object of 4.00 kg is slows down to 12 m/s.
Hence, The velocity of the 4.00 kg object after the collision is 12 m/s.
Answer:
The input force is the force that when you push down and the output force is the stable going into the paper.

Answer:
D. Nuclear fusion
Explanation:
Nuclear fusion is a nuclear reaction where nuclei of atoms( one of low atomic number and another with a higher atomic number) join together to form a much bigger nucleus and release a lot of energy.In the sun, which is a star of course, where light is released,hydrogen is converted to helium and the process releases massive energy into space in form of heat and light.
Answer:
The minimum difference between the lengths of the two tubes should be 0.385 meters.
Explanation:
As we known that for any two waves to arrive in phase at any point the difference in the path traveled by the waves should be an integral multiple of the wavelength of the wave.
Mathematically we can write:
For the given wave we have
Applying values we get
Thus the minimum difference in the lengths of the tubes can be obtained by putting the value of n = 1
