A plane electromagnetic sinusoidal wave of frequency 30.0 MHz travels in free space in the negative z direction. At some point and at some instant, the electric field has its maximum value of 200 N/C along the y-axis. (a) What is the wavelength of the wave

The least penetrating form of radiation is

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
