Suppose and equation relating position, x, to time t is give by x = bt3 + ct4, where b and c are constants. Work out the dimensions of b and c. (Dimensions are indicated in capital, dont use the symbol for the unit).

3is a crest4 is a trough 2 is the amplitude 1 is the wavelength

Wind or electric energy force force of friction

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
