a) One of the moons of Jupiter, named Io, has an orbital radius of 4.22 108 m and a period of 1.77 days. Assuming the orbit is c
hoa [83]

Answer:

According to Kepler's 3rd law.

It states that the orbital period, T is related to the distance, r as:

T² =  4 π²r³ /G  M

where G is the universal gravitational constant  =  6.673 × 10⁻¹¹ Nm²/kg²

Rearranging for M should give Jupiter's mass.

M =   4 π²r³/GT²

T= 1.77 days × 24 h/day × 60 min/h × 60 s/min = 1.53 × 10⁵ s

r = 4.22x10⁸ m

M = 4π² ((4.22 × 10⁸ m)³/(6.673 × 10⁻¹¹ Nm²/kg² x (1.53 × 10⁵ s)²)

M = 1.90 × 10²⁷kg

The mass of Jupiter is 1.90 × 10²⁷kg.

1.90 × 10²⁷kg

T= 7.16 days × 24 h/day × 60 min/h × 60 s/min = 6.19 × 10⁵s

r = 1.07x10⁹ m

M = 4π² ((1.07 × 10⁹ m)³/(6.673 × 10⁻¹¹ Nm²/kg² x (6.19 × 10⁵ s)²)

M = 1.90 × 10¹⁷kg

The mass of Jupiter is 1.90 × 10¹⁷kg.

THE RESULTS TO PART A and B ARE NOT CONSISTENT. The reason is because of the difference in radius of each satellites from Jupiter. i.e the farther away the moons, the smaller they become in space and the more the number of days to complete an orbit.

Which of the following statements are true? Check all that apply.
lidiya [134]

We have 6 levels and we will verify which of them is true.

<em>A ) Electric charge is conserved </em>

According to the conservation of charge, an electric charge can neither be created nor be destroyed.

Therefore this statement is TRUE.

<em>B ) A positive charge and negative charge attract each other</em>

According to the properties of charges, the opposite charges attract each other and similar charges repel each other

Therefore this statement is  TRUE

<em>C) Two positive charges attract each other.</em>

Using the previous law, we can observe that this statement is false, because equal charges repel each other.

Therefore this statement is FALSE.

<em>D ) Two negative charges repel each other.</em>

Using the same principle as the two previous statements, two equal charges repel each other.

Therefore this statement is TRUE

<em>E) Electric charge is quantized.</em>

According to the quantization of charge, charges can take values only in integral multiples of a fundamental unit of charge.

Therefore this statement is TRUE.

<em>F) A neutral object contains no charge.</em>

A neutral object contains equal amount of negative and positive charge. Thus, in totality a neutral object contains no charge.

Therefore this statement is TRUE.

What would always be true of an object possessing a potential energy of 0 joules
Elenna [48]
<em>if the object has 0 potential energy it means it is on ground ..
<u>explanation :
</u>
to measure potential energy we take ground as a reference point but when object is placed on reference point i.e ground then height is 0..
as potential energy = mgh .. here h becomes 0 so potential energy is 0 joules..</em>
