Answer: Period = 0.2 seconds; frequency = 5Hz
Explanation:
Number of oscillations = 50
Time required = 10 seconds
Period (T) = ?
Frequency of the oscillations (F) = ?
A) Recall that frequency is the number of oscillations that the mass spring system completes in one second.
i.e Frequency = (Number of oscillations / time taken)
F = 50/10 = 5Hz
B) Period, T is inversely proportional to frequency. i.e Period = 1/Frequency
T = 1/5Hz
T = 0.2 seconds
Thus, the the period and frequency of the oscillations are 0.2 seconds and 5Hz respectively.
The centripetal acceleration of the car is 48,800 mi/h2
Answer:
ω' = 2.5 rad/s
Explanation:
mass of cockroach, m = 4 kg
mass of disk, M = 6 kg
Radius of disc= R
initial angular velocity, ω = 2 rad/s
Let the final angular velocity is ω'
As no external torque is applied, so the angular momentum is constant.
Angular momentum = Moment of inertia x angular velocity
I ω = I' ω'
ω' = 2.5 rad/s
The three types of equilibrium in an object are; stable, unstable, or neutral equilibrium.
<h3>What is equilibrium?</h3>
The term equilibrium refers to a situation in which all the forces acting on an object are balanced such that the object does not move. The question is incomplete as the images are missing.
There are three types of equilibrium:
- Stable equilibrium: In a stable equilibrium, the object returns to rest in its original place when displlaced.
- Unstable equilibrium: In this type of equilibrium, the body moves further away from its original position when displaced.
- Neutral equilibrium: In this type of equilibrium, the object comes to rest in a new position when displaced.

Answer:
Option C
Explanation:
As we know, weight = mass x acceleration due to gravity.
Therefore, the alien would weigh more on Saturn as compared to Earth because the acceleration due to gravity is more on Saturn than Earth.
