In order to decrease the friction an object experiences, you can either change
1 answer:
Answer:
Reduce its weight
Explanation:
For an object on a flat surface, the maximum force of friction experienced by the object is given by:
where
is the coefficient of friction
W is the weight of the object
As we can see from the formula, there are two ways of reducing the friction:
- Decreasing --> this coefficient depends on the material and on the roughness of the surface, so this can be changed by changing the properties of the surface
- Decreasing W, the weight --> this can be done by reducing the mass of the object

Answer:
The frequency of oscillation of the simple pendulum is 0.49 Hz.
Explanation:
Given that,
Mass of the simple pendulum, m = 0.35 kg
Length of the string to which it is attached, l = 1 m
We need to find the frequency of oscillation. The frequency of oscillation of the simple pendulum is given by :
So, the frequency of oscillation of the simple pendulum is 0.49 Hz. Hence, this is the required solution.
