Two different objects are moving with different velocities until they strike each other, stick to each other, and begin moving together. If each object’s mass is known and each object’s initial velocity is known, then the final velocity can be predicted using the law of conservation of .

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

b.transmitters send radio waves, and receivers capture radio waves.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
