While lifting a barbell over your head (just the lifting part, not the lowering part that inexorably follows) the change in gravitational energy...
a) is zero
b) is greater than the magnitude of the change in chemical energy
c) is equal to than the magnitude of the change in chemical energy
d) is less than the magnitude of the change in chemical energy

Answers

Answer 1

While lifting a barbell over your head, the change in gravitational energy (a.k.a. gravitational potential energy) is c) is equal to than the magnitude of the change in chemical energy

As you exert force to lift the barbell, your muscles convert chemical energy stored in ATP molecules into mechanical work, this energy transfer allows you to overcome the force of gravity and raise the barbell to a higher position. According to the conservation of energy principle, energy cannot be created or destroyed, only converted from one form to another. As you lift the barbell, the chemical energy stored in your muscles is transformed into gravitational potential energy.

This increase in gravitational energy is equal to the decrease in chemical energy within your body. The total energy remains constant, but its forms change during the lifting process. So therefore while lifting a barbell over your head, the change in gravitational energy (a.k.a. gravitational potential energy) is related to the change in chemical energy within your body, so the correct answer is c) is equal to than the magnitude of the change in chemical energy.

Exposure to low-level radiation resulting from industrial leakage or medical x-rays ________

Answers

Exposure to low-level radiation resulting from industrial leakage or medical x-rays can increase the risk of childhood cancer.

Low-level radiation exposure does not immediately affect health, although it can slightly raise the risk. Radiation risk can relate to both excess malignancies overall (incidence risk) as well as only excess cancers that are lethal (mortality risk).When exposed to the same radiation exposures as adults, children and adolescents face higher risks. Children have a rapid rate of cell growth and radiation sensitivity. Their youth lengthens the time it takes for any possible ionizing radiation impacts to manifest because the effects of radiation take years to develop. It is well known that childhood radiation exposure from nuclear power plant explosions, A-bomb explosions, and medical operations is linked to an increase in leukemia and thyroid cancer rates.
