Kepler's third law is an application of Newton's second law where the force is the universal force of attraction for circular orbits, where it is obtained.

T² = (4π² / G M) r³

When applying this equation to our case, the planet with a greater orbit must have a greater period.

Consequently Dean must have a period greater than San which has the smallest orbit

The correct answer is Dean has a period greater than San

) In the figure below, three charges K, L and M are placed at the corners of an equilateral triangle. If K and L are fixed, in w

abruzzese [7]

Answer:

Explanation:

Negative (-) charge M will not move towards negative (-) charge K because, same charges will not attract each other in the given case

Negative (-) charge at the M tends to move towards positive (+) charge L in the direction of B) because opposite charges attract each other.

How many electrons does it take to make up 4.33 C of charge?

Dovator [93]

Answer:

Number of electrons, $n=2.7\times 10^{19}$

Explanation:

It is given that,

Charge, q = 4.33 C

We need to find the number of electrons that make 4.33 C of charge. According to quantization of charge as :

$q=ne$

n = number of electrons

e = electron's charge

$n=\dfrac{q}{e}$

$n=\dfrac{4.33\ C}{1.6\times 10^{-19}\ C}$

$n=2.7\times 10^{19}$

So, the number of electrons are $2.7\times 10^{19}$ Hence, this is the required solution.
