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? "

Why is it important to describe motion in universal terms?

erik [133]

Answer:

Motion requires force to cause that change. The time you take to travel the distance depends upon speed; the distance travelled is measured as the length of a line between the start and end of a motion. It is an important aspect in physics. In our lives motion is important and impacts so many things that we do.

Read the sentence. telescopes or satellites _____ that neither mercury nor venus _____ a moon. which pair of verb forms correctl

vredina [299]

When there is or in-between two words, the tense is dependent upon the word that comes after or. In other words, the word that is closest to the verb will decide the form of the verb.

Since satellites is a plural form of a satellite, the verb that follows <em>satellites</em> should also be plural. The plural verb in the given options is prove.

As far as the second blank is concerned, you can see Venus is a proper noun; therefore, the verb that comes after <em>Venus</em> should be a singular verb, which in this case is has.

So the complete sentence would become the following:

Telescopes and satellites prove that neither Mercury nor Venus has a moon.

Correct pair: prove:has

A truck moving at 13.3 m/s hits a concrete wall. As a result of the collision, a 6-kg wrench moves forwards and strikes the wall

Naddik [55]

Answer:

Explanation:

The velocity of the wrench must be equal to the velocity of the truck . So momentum of the wrench before it hits the wall

= mv = 6 x 13.3 = 79.8 kg m /s

If resisting force of wall be F , impulse on the wrench = F x time

= F x .07

Impulse = change in momentum of the wrench = mv - 0 = mv = 79.8 kgm/s

So F x .07 = 79.8

F = 1140 N .
