The broom handle that she have to balance if she hung a 400g mass from the end of the broom handle is 5.24m
This problem is centered on moment. Moment is the turning effect of a force about a point. It is expressed as:
Moment = Force× Distance
According to principle of moment, the sum of clockwise moment is equal to sum of anticlockwise moment at shown
M1d1 = M2d2
Given the following
M1 = 1.5kg
d1 = 1.4m
M2 = 400g = 0.4kg
d2 is required
Substitute
1.5(1.4) = 0.4d2
2.1 = 0.4d2
d2 = 2.1/0.4
d2 = 5.24m
Hence the broom handle that she have to if she hung a 400g mass from the end of the broom handle is 5.24m

Answer:
1.56 J
Explanation:
given,
Spring compression, x = 2.5 cm
Force exerts by the spring,
F = - k x
k = 5000 N/m
Potential energy stored = ?
energy stored in the spring
PE = 1.56 J
Hence, the potential energy stored in the car is equal to 1.56 J.

Answer:
A biome that is also known as the snow forest or boreal forest is called the taiga forest. This forest is characterized by the presence of the coniferous tress.
Explanation:
-
It is the largest known biome and is known to contain the soil that has negligible nutrient content and high acidic content.
- The limit in the organic contribution of the soil is mainly due to the cold and moist climate that does not undergo deterioration for longer period of time. Also, it adds to the thinness of the soil.
- Accompanied by the coniferous trees, the vegetation includes broad leaved trees and some herbaceous plants.
- The climate consists of longer winters and smaller summer season. Mammals, fishes and insects are present in the taiga forest along with the herbivores mammals.
