Answer:

An earthquake is a natural rapid shaking of the tectonic plates caused by the release of stored energy in rocks

Explanation:

there are tectonic plates and the earthquake is caused by that energy the plates are always moving so it might get stuck in between each other and store the energy.

To develop this problem it is necessary to use the equations of description of the simple harmonic movement in which the acceleration and angular velocity are expressed as a function of the Amplitude.

Our values are given as

$f = 4.11 *10^{12} Hz$

$A = 1.23 * 10^{-11}m$

The angular velocity of a body can be described as a function of frequency as

$\omega = 2\pi f$

$\omega = 2\pi 4.11 *10^{12}$

$\omega=2.582*10^{13} rad/s$

PART A) The expression for the maximum angular velocity is given by the amplitude so that

$V = A\omega$

$V =( 1.23 * 10^{-11})(2.582*10^{13})$

$V = = 317.586m/s$

PART B) The maximum acceleration on your part would be given by the expression

$a = A \omega^2$

$a =( 1.23 * 10^{-11})(2.582*10^{13})^2$

$a= 8.2*10^{15}m/s^2$

It is easier to roll a stone up a sloping road than to lift it vertical upwards because.

kvasek [131]

Answer:

Because the force one needs to apply is reduced.

Explanation:

Work can be expressed in terms of force and distance as follows,

Work = Force × distance

To be more precise, the selection of these two parameters should be in a manner that the distance is what the line of action of the force traces.
It is obvious that for a given amount of work when one parameter is changed the other changes to counteract the change of the first one.
Imagine the situation shown in the attached figure. The amount of work that needs to be done during the lifting of the mass to a height of $\small h$ vertically is $E = mg\times h = mgh$ .
On the slope, however, one needs to push the object an $L$ distance up to get the object to that $h$ height ultimately.
The work he does on the slope is $mgh = F\times L$ and since $L > h$ , $F < mg$ .
The force that needs to be applied is less than that applied in the vertical lift. Hence it feels easier. #SPJ4

Which statement best describes the force of gravity

Finger [1]

Gravity is measured by the acceleration that it gives to freely falling objects. At Earth's surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second.

True or False. Father of a multitude" obeyed God's command to kill His son because the Ten Commandments had not yet been given.

velikii [3]

Answer:

Explanation:

The father of the Multitude was Abraham. And he did precede the 10 commandments. But the story really has nothing to do with the 10 commandments.

He obeyed God's Command because it was God who issued it. Abraham had complete faith in God's ability to make things come out right. The sacrifice of Isaac was a test of faith.

I would advise you to answer true, but whoever wrote the question employed a twisted kind of logic. The sacrifice of Isaac had nothing to do with the 10 commandments. Thou Shalt not murder is not really covered by this circumstance.

So true might not be the correct answer. The question is very complex and does not lend itself to a simple True/ False answer.
