Two planets a and B of same mass and same radius are shown in the figure even and P2 are densities of the material in the planets and P1 is greater than PT if the acceleration due to gravity on the surfaces of the planets are G1 G2 respectively then

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
