expressed as length { in metersseconds squared, or .h divide out and T = VT2. The factor 2T has no units sod in the analysis.10. The period of rotation of the Sun is 2.125 x 106seconds. This is equivalent to 2.125(2) ms(1) us(3) Ms(4) Ts11. Human hair grows at the rate of 3 nanometersper second. This rate is equivalent to(1) 3 x 10-3 m/s(2) 3 x 10-6 m/s(3) 3 x 10-9 m/s(4) 3 x 10-12 m/s12. The wavelength of red light is 7 x 10-7 meter.Express this value in nanometers.13. If m represents mass in kg, v represents speed inm/s, and r represents radius in m, show that theforce F in the formula F =in the unit kg m/s2.mv?can be expressed14. If PE, represents the potential energy stored in aspring in kg m2/s², and x represents the changein spring length from its equilibrium position inm, what is the unit for the spring constant k inthe formula RE

On a roller coaster ride the total mass of a cart - with two passengers included - is 268 kg. Peak K is at 43.2 m above the ground and peak L is at 26.0 m. At location K the speed of the cart is 17.2 m/s, and at location L it is 12.5 m/s. (The wheel mechanism on roller coaster carts always keeps the carts safely on the rail.) K How much mechanical energy is lost due to friction between the two peaks? Submit Answer Tries 0/10
