Why does the sun have less gravitational pull on planet far away like Pluto?

Answer:

Because the planet is far away from the sun

Explanation:

The closer the planet is to the Sun, the greater the pull of the Sun's gravity, and the faster the planet orbits.

While, over here the Pluto is very far away from the Sun so it will have very little gravitational pull and still keeps revolving around the Sun

A small metal sphere weighs .28 N in air and has a volume of13

Ray Of Light [21]

To solve this problem we will start by considering how to calculate the apparent weight. On the sphere this will then be given that the real weight is the sum of the apparent weight and the Buoyant Force. Therefore we will have to

$W_T = W_A + F_B$

Here

$W_T$ = True Weight

$W_A$ = Apparent Weight

$F_B$ = Buoyant Force

If we seek to find the apparent weight we will have to,

$W_A = W_T-F_B$

$W_A = 0.28N - V\rho g$

Remember that

V = Volume (Volume Sphere)

$\rho$ = Density (At this case water density)

g = Gravitational acceleration

$W_A = 0.28N - (13*10^{-6}m^3)(1000kg/m^3)(9.8)$

$W_A = 0.1526N$

Therefore the apparent weight will be 0.1526N

When a satellite is a distance R from the center of the Earth, the force of gravity on the satellite is F. What is the gravitati

Lubov Fominskaja [6]

Gravitational force on a satellite is given by the formula

$F = \frac{GMm}{r^2}$

now here we know that force on the satellite is F when its distance from center of Earth is R

Now the distance from the center of earth will be 3R so the force is given as

$F' = \frac{GMm}{(3R)^2}$

$F' = \frac{GMm}{9R^2}$

so if we compare it with initial value of force then it is

$F' = \frac{F}{9}$

so correct answer is

$(1) F/9$

Which of the following contributes to the phases of the Moon as seen from Earth?

balandron [24]

Answer: Varying amounts of the Moon's lit surface being visible from Earth.

Explanation:

Phases of the moon can be defined as the different shapes of the moon visible from the Earth. This happens because sun lits up the face of moon and due to different position of moon in the orbit around earth, varying portion of the lit surface of the moon is visible from Earth. Refer to the diagram below:
