Newton’s 3rd Law: for every action there is an equal but opposite reaction.
Assuming that the box is motionless, we can say the force is -20N
Answer:
False
Explanation:
Diffraction is slight bending of the light as it passes around edge of object.
It is caused as one wave of the light being shifted by the diffracting object. The shift will then cause wave to have the interference with itself. The interference can be constructive or destructive.
The patterns of the interference rely on size of diffracting object and size of wave.
Hence, the given statement is incorrect.
Answer:
The second option: 11 kg * m/s
Explanation:
Recall that linear momentum is defined as the product of the mass times its velocity, therefore in this case, the mass is 0.45 kg , and the speed is 25 m/s, therefore the linear momentum is:
P = m * v = 0.45 Kg * 25 m/s = 11.25 kg * m/s
So roundng the answer to the nearest whole number, you get 11 kg * m/s, which is the second option they give you.
FALSE, a hypothesis REQUIRES an observed pattern in nautre, WITH attempting to explain.
