Answer:
The motion of a simple pendulum is very close to Simple Harmonic Motion (SHM). SHM results whenever a restoring force is proportional to the displacement, a relationship often known as Hooke's Law when applied to springs. Where F is the restoring force, k is the spring constant, and x is the displacement.
where θ is the angle the pendulum makes with the vertical. For small angles, sin(θ)∼θ, which would then lead to simple harmonic motion. For large angles, this approximation no longer holds, and the motion is not considered to be simple harmonic motion.
Answer:
<em>The tension force of the cable is 588 N</em>
Explanation:
<u>Net Force</u>
The Second Newton's law establishes that the acceleration an object has depends on the net force through the equation:
F = m.a
If the net force is zero, then the acceleration is zero, and the object's velocity remains constant.
The crane lifts a 60 Kg load at a constant velocity. It means the net force acting on the load is zero.
There are two forces acting on the load: The weight of the load and the tension of the cable that holds it.
Since the net force is zero, both forces have the same magnitude:
T=588 N
The tension force of the cable is 588 N

Answer:
The angle is 89°.
Explanation:
Given that,
Electric field = 10 N/C
Electric flux = 0.01 N-m²/C
Area
We need to calculate the angle
Using formula of electric flux
Where, E = electric field
= electric flux
A = area
Put the value into the formula
Hence, The angle is 89°.
