Efficiency is completing a task as fast a possible the the least amount of effort.
Normal force is the force exerted when an object is on an surface. So an example could be a pile of books on top of a table.
Resultant is the correct answer!
Answer:
there is friction between the two things
Explanation:
Answer:
Time period of the motion will remain the same while the amplitude of the motion will change
Explanation:
As we know that time period of oscillation of spring block system is given as

now we know that
M = mass of the object
k = spring constant
So here we know that the time period is independent of the gravity
while the maximum displacement of the spring from its mean position will depends on the gravity as


so we can say that
Time period of the motion will remain the same while the amplitude of the motion will change
