The object with the greater mass should be attached to the spring with the smaller spring constant, so that the resulting spring-object system has the greatest possible period of oscillation.
Answer: Option D
<u>Explanation:
</u>
According to the simple harmonic motions, from physics, it gives a relation between deformation force and the deflection. The more deflection results in more time period of oscillation.
F = - k x
where ‘k’ is the spring constant, and ‘F’ is the deformation force.
So, deflection is directly proportionate to forces, and inversely proportionate to its spring constant. Hence, we can derive that the force must be maximum, and hence weight must be maximum, with the spring constant lesser. Then, the deflection will be high. So, time period increases.
the answer is A. Their is less friction between the tire and the road at position A than at position B.
D. Mechanical energy remains unchanged.
Mechanical energy = Potential energy + Kinetic energy
So if potential energy decreases, then kinetic energy must increase so that the system is balanced.
I believe the answer is Eris
