You want to describe the harmonic motion of a swing. You find out that it take 2 seconds for the swing to complete one cycle. The swing passes through 48 degrees as it goes from high point-to-high point in its motion (passing through a center).
a. What is the period of the swing?

b. What is the frequency of the swing in hertz?

c. What is the amplitude of the swing?

Answers

Answer 1

Answer:

If it takes the swing 2 seconds to complete one cycle, then

that's the period of its motion ... 2 seconds.

The frequency is the reciprocal of the period ... 1/2 Hz.

('Hz' means 'per second'.)

A box has a mass of 30kg and accelerates at a rate of 3 m/s. If the force of friction on the box is 20N, how much force did YOU exert in order to move it?

Answers

The forward force is obtained to be 110 N

What is the net force?

The net force is the force that actually causes an object to move. Let us recall that force is a vector quantity. This implies that the direction of the force must also be taken into account. A force has both magnitude and directions. The direction is the area towards which a force acts.

We know that the direction of the friction is opposite to that of the force that tends to move the box forward. Thus we could write that;

Net force = Forward force - Frictional force

Note that the frictional force is negative because it is acting in opposite direction to the force that moves the object forward which has been taken to arbitrarily act in the positive direction.

Net force = ma

m = mass

a = acceleration

Net force = 30 Kg * 3 m/s^2 = 90 N

Forward force = 90 N + 20 N

110 N

Hence, the forward force is obtained to be 110 N.

Water is found all three states of matter - solid, liquid, and gas. If you place an ice cube in a pan and melt it to water and then heat it to steam, this is a physical change. Why isn't this a chemical change?

Answers

Explanation:

The elemental, chemical makeup of water (that is, Hâ‚‚0) is the same no matter what state of matter it is in.

Since it is not losing or gaining any atoms when it changes states of matter, it is simply a physical change.

I hope I helped!

because it is still the same substance. a chemical change is completely changing to a different thing. in all of the states, ice water and steam, it is still the same substance.

Property values have increased by 30% over the last few years, and that also means that property taxes have increased as well. Many politicians, such as Katherine Robertson, are interested in raising taxes even further to help pay for new infrastructure, but we are already taxed to the maximum we can afford. We are now facing an election year, and if we don't fight to keep her out of office, then our property taxes will rise to the point where no one can afford to live here anymore.Should the writer keep or delete the underlined text? Keep it, because it expands on the claim established in the first sentence. Keep it, because it provides a real-world example to support the data given earlier.
