A 8.0-m long wire with a mass of 10 g is under tension. A transverse wave for which the frequency is , the wavelength is , and the amplitude is is propagating on the wire. The maximum transverse acceleration of a point on a wire is closest to

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
