You push on a box and are unable to move it. What force opposes your push
Answers
Final answer:
The force that opposes your push when you attempt to move a box is the frictional force. In a situation where the box doesn't move, it is specifically static friction. If the box was to move, the opposing force would then be kinetic friction.
Explanation:
When you push on a box and find it difficult to move, the force opposing your push is known as frictional force. This is a resistive force that opposes the motion of an object. In a scenario where the box doesn't move at all despite your push, the static friction is equal to the applied force. However, if the box moves, it is the kinetic friction that is work. Frictional force depends on the nature of the contact surfaces and the normal force (force pushing the two surfaces together).

so if wavelength is longer the frequency is shorter
since yellow light has longer wavelength than green light
yellow light has a shorter frequency than green light
so green light has a higher frequency

Answer:
Time taken, t = 40 minutes
Explanation:
Given that,
Distance covered, d = 30 km
Speed of the person, v = 0.75 km/min
Time taken by the person is given by :
t = 40 minutes
So, the time taken by the person is 40 minutes. Hence, this is the required solution.
