Cesium-137 is used as a source of gamma radiation in cancer treatment. Each nucleus of this isotope releases one gamma particle plus one beta particle during its
decay, Placed in sensors in oil-drilling equipment, the isotope is used to detect geological formations. Using nuclear notation, write the balanced nuclear equation
representing the beta and gamma radiation emission of the isotope cesium-137,

b.a device that inputs heat into a cool object

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
