Answer:
T = 10010 N
Explanation:
To solve this problem we must use the translational equilibrium relation, let's set a reference frame
X axis
Fₓ-Fₓ = 0
Fₓ = Fₓ
whereby the horizontal components of the tension in the cable cancel
Y Axis
2
= W
let's use trigonometry to find the angles
tan θ = y / x
θ = tan⁻¹ (0.30 / 0.50 L)
θ = tan⁻¹ (0.30 / 0.50 15)
θ = 2.29º
the components of stress are
F_{y} = T sin θ
we substitute
2 T sin θ = W
T = W / 2sin θ
T = 
T = 10010 N
A habitat is a part of the ecosystem, while a niche is everything about the ecosystem.
A pendulum oscillates 40 times in 4 seconds. Find it's time period and frequency.
- The time period
- Its Frequency
Frequency of oscillation is defined as the number of oscillation of a vibrating body per second.It is given by
The time period
The time required to complete one oscillation is known as Time period.
It is given by the inverse of the frequency.
________________
Therefore the frequency is
And the time period is

Answer:
An unmoving object will remain unmoving and a moving object in motion will continue to be in motion with the same velocity unless an external force acts upon it.
Answer:
The net force is 500N downwards
Explanation:
When Haley is trying to pull an object upward. The below forces are acting on the object.
Fp = 5500N
Fg = 6000N
because the force of gravity is more than the force of the pull.
Fnet = Fg - Fp = 6000N - 5500N = 500N
And, the direction of the resultant force is the direction of the larger force.
