Convert 3.5revolutions to radians.
olga55 [171]

As we know that

1 revolution = 2\pi radian

now we know that

3.5 revolution = 3.5 rev\times \frac{2\pi rad}{1 rev}

3.5 rev = 21.98 rad

so it is 21.98 radian

Which expression allows you to determine the mechanical advantage of an inclined plane?
Leya [2.2K]

Answer:

(C) length / height of the plane

Explanation:

The mechanical advantage of an inclined plane can be determined using different variables. In this case, the geometry of the setup is relevant. The advantage is proportional  to the length of the plane, and inversely proportional to the height: it is the ratio (length) / (height) of the plane. For example, given a desired, fixed height, a long inclined plane gives you a bigger mechanical advantage than a short inclined plane. In this example, pushing an object up the long plane will require a smaller force, than it would on the short plane.

Strictly speaking, (D) would also "allow you to determine the mechanical advantage" because you could simply invert the ratio listed under (D). However, (C) is the best, direct, answer.

A pendulum swings back and forth. If the mass of the pendulum is 3kg and it starts from a height of 1m.How much kinetic energy d
tatiyna

From the principle of energy conservation, the kinetic energy of the pendulum at 0.5 m is 14.7 J.

<h3>What is a pendulum?</h3>

A pendulum swings back and forth and can be used to show the change of potential energy to kinetic energy and vice versa.

Given that the kinetic energy is converted to the potential energy; the potential energy at 0.5 m is 3 * 9.8 * 0.5 = 14.7 J.

Following the principle of energy conservation, the kinetic energy of the pendulum at 0.5 m is 14.7 J.
