A physician is going to use high-frequency electromagnetic radiation to treat cancer in a patient. Which is a claim about this event?(1 point)A wave model is most useful for describing the frequency of the radiation.Using gamma rays is the best to treat cancer because they act like particles.The radiation will destroy the cells by transferring energy to them.All of the cancer cells in the targeted region will be destroyed by the radiation.

A student states, "The wave model is better than the particle model for electromagnetic radiation because it is easier to understand." Is the student's statement a scientific claim?(1 point)Yes, it is because simpler scientific models are better.No, it isn't because the particle model is better than the wave model.No, it isn't because the statement is an opinion.Yes, it is because there is ample proof that wave models are easier.

Daryl uses a microphone connected to an oscilloscope to study sound waves. He finds that higher pitched sounds have higher frequencies and shorter wavelengths while lower pitched sounds have lower frequencies and longer wavelengths. Daryl concludes that the relationship between the frequency and the wavelength of sound waves in air is the result of causation and not correlation. In two to three sentences, describe whether Daryls conclusion is correct and explain why or why not.

A stage has a radius R = 2.00 m and a mass M = 100 kg. The stage, which has a circular disk shape, rotates in a horizontal plane, without any friction, about a vertical axle. Sandra has a mass of m = 60.0 kg and she walks from the rim of the stage toward the center. Calculate the angular speed when she reaches a point r = 0.500 m from the center, if the angular speed of the system is 2.0 rad/s when Sandra is at the rim

PLEASE HELP!! A TOTAL OF 50 POINTS WHEN GIVEN BRAINLIEST!!Part A: Find the work done in lifting 1 L of blood (mass 1 kg ) from the foot to the head of a 1.9 m -tall person. Part B: If blood circulates through the body at the rate of 5.0 L/min , estimate the heart's power output. (Your answer underestimates the power by a factor of about 5 because it neglects fluid friction and other factors.)
