What is the magnitude of the gravitational force of attraction to Jupiter exerts on IO

kotegsom [21]

The gravity force between Jupiter and Io will be 6.343 × 10²² N.

<h3>What is Newton's law of gravitation?</h3>

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Given data;

Mass of Jupiter, $\rm m_j = 1.9 \times 10^{27} \ kg$

Mass of moon of Jupiter, $\rm m_{i_0}= 8.9 \times 10^{22} \ kg$ ]

The gravitational constant is, $\rm G = 6.67 \times 10^{-11 } \ m^3 kg^{-1} s^{-2}$

Distance between Jupiter and Io, R = 421,700 km = 4,217,00,000 m

The gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

The gravitational force is found as;

$\rm F = G \frac{ m_J m_{I_0}}{R^2} \\\\\ F = (6.67\times 10^{-11}) \frac{( (1.9\times 10^{27})\times (8.9\times 10^{22} )} { (421700000)^2}\\\\ F_g = 6.343 \times 10^{22} \ N$

Hence, the gravity force between Jupiter and Io will be 6.343 × 10²² N.

The complete question is

"Jupiter has a mass of 1.9 × 1027 kg, and its moon Io has a mass of 8.9 × 1022 kg. Their centers are separated by a distance of 421,700 km what is the force of gravity acting on Io? "

A 50.0 kg piece of rock slides down the side of Mt. Etna. That part of the volcano slopes up at 30.0° (from the horizontal). If

vesna_86 [32]

Answer:

0.224

Explanation:

There are two forces acting on the rock along the direction parallel to the slope:

- The component of the weight parallel to the slope, down, given by

$mg sin \theta$

where

m = 50.0 kg is the mass of the rock

$g=9.8 m/s^2$ is the acceleration of gravity

$\theta=30^{\circ}$ is the angle of the slope

- The force of friction, up along the slope, given by

$F_f=\mu R$

where

$\mu$ is the coefficient of friction

R is the normal reaction

So the equation of the forces along the direction parallel to the slope is

$mg sin \theta - \mu R = ma$ (1)

where

$a=3.0 m/s^2$ is the acceleration

The normal reaction R can be found by looking at the equation of the forces along the direction perpendicular to the slope: in fact, we have that R balances the component of the weight perpendicular to the slope, so

$R=mg cos \theta$

And substituting into (1)

$mg sin \theta - \mu mg cos \theta = ma$

And solving for $\mu$ , we find the coefficient of friction:

$\mu = \frac{g sin \theta -a}{g cos \theta}=\frac{(9.8)(sin 30)-3.0}{(9.8)(cos 30)}=0.224$

1) How much work does it take to accelerate a 8.2 kg<br> object from rest to 19 m/s?

krek1111 [17]

Explanation:

Work = change in energy

W = ½ mv²

W = ½ (8.2 kg) (19 m/s)²

W ≈ 1500 J

What is the chemical formula for copper (I) sulfide? A) CuS B) CuS2 C) Cu2S D) Cu2S3

Ganezh [65]

This problem can be solved by using oxidation states. The oxidation state is based on the electrons an atom loses or gain, or appears to use when forming compounds.To find the formula for Copper (I) Sulfide, we have to first consider the individual ions that come together to form it. Copper (I) is an ion of copper that has a charge of +1, i.e $Cu^{+}$ . Sulfur is an element in group 6 of the periodic table. The sulfur ion has a charge of -2, i.e $S^{2-}$ . To form Copper (I) Sulfide, which is electrically neutral, we need 2 Copper (I) ions and 1 sulfur ion.

$Cu_2S= 2Cu^+ 1S^-^2= 2(+1) + (-2) = 0$ .

The reaction is represented by the equation below

$2Cu^{+} +S^{2-}-->Cu_2S$ .

The correct answer is (C)

When you jump, you exert a pushing force against the ground. Gravity pulls you back down. Why can a person jump higher on the mo

Dennis_Churaev [7]

Answer:

This is because the force of gravity is much less on the moon than on the earth, therefore the person wont be pulled down much and will jump higher
