9.4 × 10⁻¹⁹ J. (2 sig. fig).
<h3>Explanation</h3>
The kinetic energy of an object depends on its mass and its speed. Mass is given for this neutron. However, the speed of the neutron needs to be found.
What's the speed of this neutron?
(3 sig. fig. Speed is an intermediate quantity. Include at least one more sig. fig. for the value of kinetic energy to be accurate to 2 sig. fig.)
What's the kinetic energy of this neutron?
,
where
- is the mass of the object, and
- is the speed of the object.
.
(2 sig. fig as in mass, distance travelled, and time).
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.
