Answer:

Explanation:

Its C, because all the other planets have A, B, and D. But since earth is just far enough from the sun, it can support life. I think its called liek the perfect area section. Also, mars is too far, venus is the hottest planet, and mercury doesn't even have an atmosphere. im not going to go farther from the astroid belt.

In 5 meters, a person running at 0.8 m/s accelerates at 1.6 m/s2. How fast 16 points

frutty [35]

They were going at a velocity 4.07m/s

<u>Explanation:</u>

Distance s =5 m

initial velocity u= 0.8 m/s

Acceleration a =1.6m/s2

We have to calculate the velocity with which they were going afterwards i.e final velocity.

Use the equation of motion

$v^2=u^2+2as\\=0.8^2+2\times 1.6\times 5\\=16.64\\v=4.07 m/s$

They were going with a velocity 4.07 m/s afterwards.

Two particles collide, one of which was initially moving and the other initially at rest. Is it possible for both particles to b

solmaris [256]

Answer:

Not possible

Explanation:

Unless there's some extra external force to keep both particles at rest after the collision, the momentum must be conserved before and after the collision.

So before the collision, 1 particle is at rest, 1 not -> total momentum is non-zero

After the collision, both particles are at rest -> total momentum is zero which is different from before.

Therefore this is not possible.

Conduction occurs more easily between solids and liquids. This is because the particles in gases are A) further apart and move f

valkas [14]

The answer is A. Further apart and move faster.

Conduction in general is the transfer of energy from molecule to molecule through DIRECT CONTACT. In solids and liquids, the molecules are closer to each other; more so in solids than liquids. This enables them to pass energy more quickly. Gas molecules on the other hand are further apart and move faster because they have space to move more freely. Energy does not easily pass on to the next molecule because of the distance between the molecules.

Drop a rock from a 5-m height and it accelerates at 9.81 m/s^2 and strikes the ground 1s later. Drop the sane rock from a height

KiRa [710]

Answer:

A. The same amount

Explanation:

The acceleration at which objects free falls to the ground on Earth is constant and its value is always $9.81 m/s^2$ , regardless of their mass (in this problem we neglect air resistance).
