Answer:
Explanation:For example, you are in a bus and it goes with the velocity of 50 m/s to the east, then a truck passes you with a velocity of 60m/s to the east. ... Velocity of the moving objects with respect to other moving or stationary object is called “relative velocity” and this motion is called “relative motion”
Answer:
option C is correct
Explanation:
oxidation number is the apparent charge on an atom which it acquire after lose or gain of electron
This will be highly depended on the case,
for example, when hydrogen attached to electromotive atom, we call it hydrogen bonding.
if the electrons in two atoms make them temporary dipole, we called it london dispersion forces, etc

The answer is B. Lithosphere
Explanation: The upper layer of mantle is a zone of rigid brittle rock. Below the lithosphere is asphalt-like and is called the Asthenosphere.
Answer:
False
Explanation:
The increase in the temperature of a liquid also increases the rate of evaporation, as the same for the other way around. As intermolecular force increase rate of evaporation decreases. This happens because intermolecular force make it less likely for the molecules on the surface to escape from liquid and become vapour gas. As temperature increases rate of evaporation increases.
