The “human cannonball” has long been a popular - and extremely dangerous - circus stunt. In order for a 45 kg person to leave the cannon with the fastest possible velocity yet achieved by a human
cannonball, a 1.6x10^3N force must be exerted on that person for 0.68 s. What is the record speed at
which a person has been shot from a circus cannon? (24.2 m/s)

What pressure difference is required between the ends of a 2.0-m-long, 1.0-mm-diameter horizontal tube for 40 c water to flow through it at an average speed of 4.0 m/s?

Which is an example of an exothermic process?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
