Answer: The velocity of the first ball is 0.875 m/s if the second ball travels at 1.5 m/s after collision.
Explanation:
Given: 
= 0.2 kg, 
= 0.15 kg
= 2 m/s, 
= 0 m/s, 
= ?, 
= 1.5 m/s
Formula used is as follows.
where,
v = velocity before collision
v' = velocity after collision
Substitute the values into above formula as follows.
Thus, we can conclude that the velocity of the first ball is 0.875 m/s if the second ball travels at 1.5 m/s after collision.

Explanation:
It means that the heat comes directly at you without relying on any material to conduct it.
For example, you feel the heat from a campfire even if the wind is blowing crosswise to you and the fire.
Answer : Density of any particular matter remains the same at any concentration at any weight.
Density does not varies with the concentration. The formula for density is mass / volume.
So if the mass changes the density will change accordingly, also if the volume changes the density will get changed.
because, of the above reasons density is referred as a characteristic property of matter.
