The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.724 w/m2. what is the maximum value of the magnetic field in the wave? (c=3.0×108m/s, μ0=4π×10−7t⋅m/a, ε0=8.85×10−12c2/n⋅m2)

Which body part transports oxygen removes waste materials in carries nutrients to the body as part of the circulatory system

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
