The motion of the branch being shaken causes the fruit to detach off the branch, and gravity helps make the fruit fall.

Answer:

becauae of the gravity

Explanation:

Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

They proposed that gravity is actually made of quantum particles, which they called "gravitons." Anywhere there is gravity, there would be gravitons: on earth, in solar systems, and most importantly in the miniscule infant universe where quantum fluctuations of gravitons sprung up, bending pockets of this tiny space

Suppose you are asked to find the amount of time t, in seconds, it takes for the turntable to reach its final rotational speed.
Inga [223]

Answer:

it will take t=\frac{\omega -\omega _0}{\alpha } to reach its final rotating speed

Explanation:

Let initially the turntable is at rest

So its initial angular velocity will be \omega _0=0rad/sec

Let the turn table is rotating with an angular acceleration \alpha

According to first equation of motion

We know that \omega =\omega _0+\alpha t , here \omega

So t=\frac{\omega -\omega _0}{\alpha }

So it will take t=\frac{\omega -\omega _0}{\alpha } to reach its final rotating speed

How would the Earth move if the sun (including its gravity) suddenly disappeared? Explain your answer.

It would float outward as all space is expanding from the center constantly. of by some chance it for caught in the orbit of another celestial body with huge mass it may orbit that, bur other wise it would just push outward from the center of the universe theoretically the big bang

A purse at radius 2.30 m and a wallet at radius 3.45 m travel in uniform circular motion on the floor of a merry-go-round as the
ivolga24 [154]

Answer:

The acceleration of the wallet is 3\hat{i}+6\hat{j}

Explanation:

Given that,

Radius of purse r= 2.30 m

Radius of wallet r'= 3.45 m

Acceleration of the purse a=2\hat{i}+4.00\hat{j}

We need to calculate the acceleration of the wallet

Using formula of acceleration

a=r\omega^2

Both the purse and wallet have same angular velocity

\omega=\omega'

\sqrt{\dfrac{a}{r}}=\sqrt{\dfrac{a'}{r'}}

\dfrac{a}{r}=\dfrac{a'}{r'}

\dfrac{a'}{a}=\dfrac{r'}{r}

\dfrac{a'}{a}=\dfrac{3.45}{2.30}

\dfrac{a'}{a}=\dfrac{3}{2}

a'=\dfrac{3}{2}\times(2\hat{i}+4.00\hat{j})

a'=3\hat{i}+6\hat{j}

Hence, The acceleration of the wallet is 3\hat{i}+6\hat{j}
