Answer:
66 rpm
Explanation:
The period of oscillation is given by
where T is time period of oscillation which is given as 0.35 s, k s spring constant and m is the mass of the object attached to the spring.
Also, net force is given by
Net force=
where is the elongation, L is original length, is the angular velocity
Substituting the equation of into the above we obtain
<em>Angle of Dip is the angle in the vertical plane aligned with magnetic north (the magnetic meridian) between the local magnetic field and the horizontal.</em>
Ok, let me see if I can help
Sound is caused by vibrations. These can pass through a solid, liquid, and gas. But not through vacuum because there are no particles
The Kinetic energy would be 1/2IL².
<h3>What is
Rotational Kinetic energy ?</h3>
- Rotational energy also known as angular kinetic energy is defined as: The kinetic energy due to the rotation of an object and is part of its total kinetic energy. Rotational kinetic energy is directly proportional to the rotational inertia and the square of the magnitude of the angular velocity.
As we know linear Kinetic energy = 1/2mv²
where m= mass and v= velocity.
Similarly rotational kinetic energy is given by = 1/2IL²
where I- moment of inertia and L=angular momentum.

1. We can use the principle of moments to ensure that there is no net moment, that is, m*g*d = M*g*l, where m is the mass of the weight, d is the distance of the weight to the pivot, M is the mass of the counterweight, l is the distance of the counterweight from pivot, and g is the gravitational constant.
2. A question that could be asked is what kind of weights is the engineer expecting the crane to lift, that would determine the counterweights used.
