A forklift raises a 72-kg crate onto a shelf 3.6 meters above the floor. How much gravitational potential energy does the crate

Mademuasel [1]

Answer:

Explanation:

The gravitational potential energy of a body can be found by using the formula

GPE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

GPE = 72 × 9.8 × 3.6 = 2540.16

We have the final answer as

Hope this helps you

What is the orbital velocity in km/s and period in hours of a ring particle at the outer edge of Saturn's A ring

mote1985 [20]

Answer:

The orbital velocity $v = 16.4 \ km/s$

The period is $T = 14.8 \ hours$

Explanation:

Generally centripetal force acting ring particle is equal to the gravitational force between the ring particle and the planet , this is mathematically represented as

$\frac{GM_s * m }{r^2 } = m w^2 r$

=> $w = \sqrt{ \frac{GM}{r^3} }$

Here G is the gravitational constant with value $G = 6.67*10^{-11}$

$M_s$ is the mass of with value $M_s =5.683*10^{26} \ kg$

r is the is distance from the center of the to the outer edge of the A ring

i.e r = R + D

Here R is the radius of the planet with value $R = 60300 \ km$

D is the distance from the equator to the outer edge of the A ring with value $D = 80000 \ kg$

$r =80000 + 60300$

=> $r =140300 \ km = 1.4*10^{8} \ m$

=> $w = \sqrt{ \frac{ 6.67*10^{-11}* 5.683*10^{26}}{[1.4*10^{8}]^3} }$

=> $w = 1.175*10^{-4} \ rad/s$

Generally the orbital velocity is mathematically represented as

$v = w * r$

=> $v = 1.175*10^{-4} * 1.4*10^{8}$

=> $v = 1.64*10^{4} \ m /s = 16.4 \ km/s$

Generally the period is mathematically represented as

$T = \frac{2 \pi }{w }$

=> $T = \frac{2 * 3.142 }{ 1.175 *10^{-4} }$

=> $T = 53473 \ second = 14.8 \ hours$

Answer:

The orbital velocity $v = 16.4 \ km/s$

The period is $T = 14.8 \ hours$

Explanation:

Generally centripetal force acting ring particle is equal to the gravitational force between the ring particle and the , this is mathematically represented as

$\frac{GM_s * m }{r^2 } = m w^2 r$
