Which statements accurately relate radiation and health? Check all that apply.

Ionizing radiation produces ions that disrupt natural chemical reactions in the body.
Stochastic effects are associated with short-term, high-level exposure to radiation.
Cancer and DNA mutations are examples of non-stochastic effects.
A single X-ray delivers about of the radiation exposure permitted for one person per year.
Lead shielding is an effective means of reducing radiation exposure.

d. air pressure decreases as altitude increases.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
