Figure 13 shows a child’s toy . The toy hangs from a hook in the ceiling.
1 answer:
The number of oscillations of the toy in a second is 1.25.
<h3>What is frequency?</h3>- This is the number of complete oscillation of an object is a given period.
The given parameter:
- Frequency of the toy, F = 1.25 Hz
The frequency of an object is calculated as follows;
where;
- n is the number of oscillations
- t is the time of motion

Yes, if we know the Earth's mass
Explanation:
The momentum of an object is a vector quantity given by the equation
where
m is the mass of the object
v is its velocity
In this case, we are asked if we can find the velocity of the Earth by starting from its momentum. Indeed, we can. In fact, we can rewrite the equation above as
Therefore, if we know the momentum of the Earth (p) and we know its mass as well (m), we can solve the formula to find the Earth's velocity.
