Answer:
D
Explanation:
Hooke's law states the force exerted by a spring is the product of its spring constant and its displacement.
F = kx
Solving for the spring constant:
k = F/x
All the springs are pulled with equal force (the weight of the mass), so the spring with the smallest displacement has the largest spring coefficient.
that would be given by

@ representing coefficient of kinetic friction.
thus 19.5/51.7 = 0.377
Its been some time so i might be wrong but i think the answer is 3 either or 2
Answer:
distance covered is 4.5km or 1.25m
Explanation:
GIVEN DATA:
SPEED=v=3km/h
TIME=t=1.5h
TO FIND:
DISTANCE COVERED=d=?
SOLUTION:
As we know that
speed=distance covered /time taken
here we have to find distance
speed×time taken=distance covered
3km/h×1.5h=distance covered
4.5km=distance covered or in international system of unit the answer is 1.25m
Russian nesting dolls are an amazing comparison for the strongest magnet in the world, because the magnitis were inserted inside each other. The magnets would be adapted so they could be put together, Because they are closer, the coils of the magnet would be tougher. The magnets would be able to magnetize better.
