Wo small pith balls, each carrying a charge q, are attached to the ends of a light rod of length d, which is suspended from the ceiling by a thin torsion- free fiber. There is a uniform magnetic field B, poi If the magnetic field is turned off, which of the following describes what happened to the system? nting straight down, in the cylindrical region of radius R around the fiber. The system is initially at rest TrueIt does not rotate because to do so would violate conservation of angular momentum FaiseIt rotates with angular momentum qBd/4 True It does not move because magnetic forces do no work Fase It rotates with angular momentum qBR True It rotates with angular momentum qBRd/2

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

answer and explanation;

statement #3 on andre"s list is false.

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.
