That's true.
Radiation always carries energy.
An object at 0 K doesn't have any.
Water set free by magma began to cool down the Earth's atmosphere, until it could stay on the surface as a liquid. ... The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor.
Answer:
2nd answer 3.2m/s is a scalar l, all others are vectors.
Explanation:
In order to be considered as a vector a certain quantity must have both a magnitude and a direction.
The most common example is velocity. It has both magnitude and direction, like the 1st and the last answers.
The 3rd answer is an acceleration. It is also given with its direction. So we have to consider it also as a vector.
But 2nd answer has no direction mentioned, so it is considered as a scalar.
