Calculate the flow rate of blood (of density 1.03 g/cm3) in an aorta with a cross-sectional area of 2.88 cm2 if the flow speed is 28.5 cm/s. Answer in units of g/s.

The potential difference between a storm cloud and the ground is 2.13 × 108 V. If a bolt carrying 2 C falls from a cloud to Earth, what is the magnitude of the change of potential energy of the charge? Answer in units of J.

It takes 133 J of work to move 3 C of charge from the negative plate to the positive plate of a parallel plate capacitor. What voltage difference exists between the plates? Answer in units of V.

What career do need this subject

Matrices The U-Derive Rent a Truck Company plans to spend $5 million on 300 new vehicles. Each van will cost $15,000 and each truck $25,000. Past experience shows that U-Drive needs twice as many as trucks. How many of each kind of vehicle can the company...

Thanks!
