Stand next to a wall that travels at 30 km/s relative to the Sun. With your feet on the ground, you also travel at the same 30 k

m/s. Do you maintain this speed when your feet leave the ground? What concept supports your answer?

Answer:

Yes. Inertia keeps the speed maintained though my feet leave the ground.

Explanation:

Inertia is the resistance to the change in position of any object this means this resistance will keep me traveling at 30 km/s relative to the sun. If the person wants to change the position we apply force to do that because inertia is opposing us to not do that. We are always traveling with 30km/s relative to sun due to inertia.

How much time will elapse between seeing and hearing an event?
julia-pushkina [17]

Depends on how far away the event is and what the temperature is as this affects the speed of sound.

For example, let's say you're 600 meters away and the temperature has no affect.

The speed of sound would be roughly 340 m/s so the time it would take to hear the sound would be 600/340 = 1.76 seconds

The speed of light (c) is 3.0 X 10^8 m/s so the time it would take to see the event would be 600/3 X 10^8 = 2 X 10^-7

Subtract: 1.76 - (2 X 10^-7) = approx. 1.76

If the temperature of a gas is increased by 10x, what will happen to the volume?
xxMikexx [17]

The volume of a gas will increase by ten times if the temperature is increased by ten times.

<h3>Relationship between the volume of a gas and temperature</h3>

The relationship between the volume of a gas and its temperature is explained in Charles' law of gases which states that:

  • The volume of a fixed mass of gas is directly proportional to its temperature provided the pressure of the gas is kept constant.

This means that if the temperature of a gas is increased by any given factor, the volume increases by the same factor proportionally.

Therefore, if the volume of a gas will increase by ten times if the temperature is increased by ten times.

An object experiences an acceleration of -6.8m/s^2. As a result, it accelerates from 54m/s to a complete stop. how much distance
Kipish [7]

Answer:

210 m

Explanation:

Given:

a = -6.8 m/s²

v₀ = 54 m/s

v = 0 m/s

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (54 m/s)² + 2 (-6.8 m/s²) Δx

Δx ≈ 210 m
