5. The motion diagrams shown above
represent cyclist I's motion. Which
statement describes the velocity of cyclist 1
in the third panel above? sc.6.2.2.1
A The cyclist's velocity is changing
because her direction is changing.
The cyclist's velocity is changing
because her speed is changing
© The cyclist's velocity is constant becaust
her speed is constant.
The cyclist's velocity is constant because
speed and direction are constant.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
