Shock waves can be observed in outer space between planets where there is very little matter. Although little, plasma does exist in outer space which allows the waves to travel.
Answer:

Explanation:
From the question we are told that:
Mass of cart A 
Mass of cart B 
Speed of cart AA
Generally the equation for velocity of A after collision
is mathematically given by




Answer:
266.7k
Explanation:
Given parameters:
Initial pressure = 36Pa
Initial temperature = 300k
New pressure = 32Pa
Unknown:
New temperature = ?
Solution:
To solve this problem, we have to apply the combined gas law when the volume is constant;
in this instant, when the volume is constant, the pressure of a given mass of gas varies directly with the absolute temperature.
=
P and T are pressure and temperature
1 and 2 are initial and final states
Insert the parameters and solve;
=
T₂ = 266.7k
The object that is furthest away from earth is the cluster of galaxies. Option B
<h3>What is the solar system?</h3>
The solar system is arrangement of arrangement of the sun and the planets. The sun lies at the center of the solar system. This is known as the heliocentric model. The planets surround the sun in orbits.
Now as we move across the earth going far deeper into the outer space, we would find out that the object that is furthest away from earth is the cluster of galaxies. Option B
