I solved this Biophysics problem myself.

But obviously there are a lot of places that are wrong.

Let the experts see what's right and what's wrong and explain to me what's the right answer!

Determine which of the following expressions is dimensionally consistent distance = 1/2*accelleration*time^3 distance = velocity * time a? O velocity*2 = 2*accelleration*distance*2 velocity = distance * time No answer "In the formula below the symbol U is measured in kg*m"2 / s"2 and x stands for the length. What are the units of k? * U = -kx2 b? No answer O 2 * kg / m * 2 O 2 * kg * m * 2 O kg /5 2 O kg*m/542 3. Derive the unit of the quantity P given in the following equations * 7, a= -, F=ma, W = Fx, P= 7 No answer O kg*m* 3/542 c? O kg*m* 2/543 O kg*m* 3/543 O kg*m*2/512 Write 101 000 ns in seconds * O No answer 101 0.101 0.000101 d? 101.000 Suppose that you drive the 10.0 km from your university to home in 20.0 min. Calculate your average speed in meters per second. Average speed is the distance traveled divided by time of travel. * No answer O 8.33 m/S 3.33 m/S c ? O 0.5 m/s 500 m/s 6. Suppose you walk 1 meter per second. Calculate your speed in kilometers per hour. * 10 km/h 0.000277 km/h 0.001 km/h b ? O No answer 3.6 km/h What is the height in meters of a person who is 6 feet 1.0 inches tall? (Assume that 1 meter equals 39.37 in., and 1 feet is 12 inches) * No answer O 73 inches O 1.8542 m a? 185.42 m 6.0833 feet 8. The speed of sound is measured to be 342 m/s on a certain day. What is it in kilometers per hour? * 20.52 O 1231.2 7387.2 d? O No answer 95 The nearest star (other than the Sun) to Earth is Proxima Centauri at a distance of 4.24 light years. What is this distance expressed in metres? * O 4.01e13 4.24e15 O 9.46e13 c? No answer 4.01e16 10. A TV program lasts 2650000 s. How many days is that? * 44166.67 1840.28 a? 30.67 24.89 No
