Explanation:
3 cause the triangle method of addition are connected to tips of one vector
Answer:
Explanation:
The charge on one object,
The distance between the charges, r = 0.22 m
The force between the charges, F = 4,550 N
Let q₂ is the charge on the other sphere. The electrostatic force between two charges is given by the formula as follows :
So, the charge on the other sphere is .
Answer:
This would happen.
Explanation:
If the earth’s rotation speed increases then the weight of the body decreases. This is because you see a moving body on the rotating earth’s surface itself is in the reference frame. So when the earth rotates, the centripetal force acts towards the centre of rotation.
Answer:
The gravitational force changing velocity is
Explanation:
The expression for the gravitational force is
Differentiate the above equation
The velocity is the distance in at time so
Answer:

Explanation:
Given:
- mass of slinky,
- length of slinky,
- amplitude of wave pulse,
- time taken by the wave pulse to travel down the length,
- frequency of wave pulse,
1.
2.
<em>Now, we find the linear mass density of the slinky.</em>
We have the relation involving the tension force as:
3.
We have the relation for wavelength as:
