The speed of sound is 344m/s when the air is 20 degrees c. how far away is the source of sound if it takes 8 seconds for the sound to reach you?

What is a carrier wave and how does it affect what you hear on the radio

An isotope undergoes radioactive decay by emitting radiation that has a –1 charge. what other characteristic does the radiation have?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)
