Explanation:

Period of a mass on a spring is:

T = 2π√(m/k)

T is inversely proportional with the square root of k. So as the spring constant increases, the period decreases.

Answer:

$T\propto \dfrac{1 }{\sqrt{k}} \text{ and } k \propto \dfrac{1}{T^{2}}$

Explanation:

The period T is inversely proportional to the square root of the spring constant, and

The spring constant is inversely proportional to the square of the period.

It all comes from Hooke's Law.

We usually get the equation for the period, but we can easily rearrange it to get an equation for the spring constant.

$\begin{array}{rcl}T &= &\mathbf{2\pi \sqrt{\dfrac{m}{k}}}\\\\T^{2} &=& 4 \pi^{2} \dfrac{m}{k}\\kT^{2}& =& 4 \pi^{2}m\\k &=& \mathbf{\dfrac{4 \pi^{2}m}{T^{2}}}\end{array}$

Answer:

My scenario would be A Car vs. a guard rail on a road. You have a car that is coming down a Highway at a speed of 43 Mph Miles per hour (69.2018 Kmh)

And it hits a steel guardrail and the car smashes in at the front and the guardrail is only bent while the car has the bumper and the hood along with the headlights and windshield along with the passenger side window break.

Explanation:

This is caused by so much force reacting from one object to another but also depends on molecular density.

A cat dozes on a stationary merry-go-round, at a radius of 5.5 m from the center of the ride. Then the operator turns on the rid

bixtya [17]

Answer:

$u_{s}=0.56$

Explanation:

For the cat to stay in place on the merry go round without sliding the magnitude of maximum static friction must be equal to magnitude of centripetal force

$F_{s.max}=\frac{mv^2}{r} \\$

Where the r is the radius of merry-go-round and v is the tangential speed

but

$F_{s.max}=u_{s}F_{N}=u_{s}mg$

So we have

$u_{s}mg=\frac{mv^2}{r}\\ u_{s}=\frac{v^2}{gr}\\ Where\\v=\frac{2\pi R}{T} \\So\\u_{s}=\frac{(\frac{2\pi R}{T} )^2}{gr} \\u_{s}=\frac{4\pi^2 r}{gT^2}$

Substitute the given values

$u_{s}=\frac{4\pi^2 5.5m}{(9.8m/s^2)(6.3s)^2} \\u_{s}=0.56$

How did Aristotle contribute to science?

Nimfa-mama [501]

He made pioneering contributions to all fields of philosophy and science, he invented the field of formal logic, and he identified the various scientific disciplines and explored their relationships to each other. Aristotle was also a teacher and founded his own school in Athens, known as the Lyceum.

If the resistance in a circuit remains constant, what happens to the electric power when the current increases?

bearhunter [10]

If the resistance in a circuit remains constant and the current increases, then the power will increase. (A)

In fact, it'll increase as fast as the square of the current ! Like, if the current somehow increases to 3 times as much, the circuit will start using 9 times as much power as it did before.

Inga [223]

1) The forces of molecules is how strong they are being held together. Now, we know that solid is the last one, because it's particles are held CLOSELY and VERY TIGHTLY together, which is why it has a definite shape.And last of all, a gas's particles are held freely, which is why it has no shape. So the answer would be:- gas, liquid, solid

3) The state of matter that does not have a definite shape, but has a definite volume is a liquid. So the answer is :- liquid

7) False, an endothermic reaction is when it absorbs energy, and as we know that in a chemical reaction as the following, it tends to be an exothermic reaction, meaning that is releases energy. So the answer is:- FALSE

8) Gases have particles that are far apart (freely) and move fast. So the answer is:- They are moving very fast and are far apart.
