What type of material is thought to explain the larger size of the outer planets relative to the inner planets
svetoff [14.1K]

The material which is believed to explain the larger size of the outer planet in relation to the inner planet is gas while the inner is made of rock

Research on the solar system reveal to us that it is temperature of the the solar system that perfectly explain the materials both the outer and inner planets are made up of. The outer part is highly gaseous while the inner part is made of rocks

<h3>What is outer planet?</h3>

It refers to planet whose orbit lies outside the asteroid belt. Examples include Jupiter, Saturn, Uranus, or Neptune.

<h3>What is inner planet?</h3>

This simply means a planet whose orbit lies within the asteroid belt. They are planets such as Mercury, Venus, Earth, or Mars.

Heather and Matt take 34 minutes to walk eastward along a straight road to a store 2.0km away. What is their average velocity in
frez [133]

Their average velocity is 0.98 m/s east.

Explanation:

The average velocity of an object is defined as the ratio between the displacement and the time taken:

v=\frac{displacement}{time}

The displacement is a vector connecting the initial point to the final point of motion: so, being displacement a vector, velocity is a vector as well, having the same direction of displacement.

Here, Heather and Matt walk 2.0 km eastward, so their displacement is

d = 2.0 km = 2000 m (east)

While the time they took is

t=34 min \cdot 60 = 2040 s

Therefore, their average velocity is

v=\frac{2000}{2040}=0.98 m/s

And the direction is the same as the displacement (east).

What is the acceleration of a 1000 kg car subject to a 550 N net force
Xelga [282]

Answer:

The acceleration of a 1000 kg car subject to a 550 N net force = 0.55 m/s^2

Explanation:

Given:

F = 550 N

m = 1000 kg

To Find:

a = ?

Solution:

So by the equation by Newton's 2nd Law of Motion,

F = m x a

550 N = 1000 kg x a

a = 550 N/ 1000 kg

a = 0.55 m/s^2

Therefore,

The acceleration of a 1000 kg car subject to a 550 N net force = 0.55 m/s^2
