The rotating loop in an AC generator is a square l on each side. It is rotated at frequency f in a uniform field of B. The generator is loaded with a resistor of resistance R. Give formulas in terms of l, B, f , and R for the following quantities:
a. the flux Φ (t) through the loop as a function of time
b. the emf Σ(t) induced in the lop
c. the current I(t) induced in the resistor
d. the power R(t) delivered to the resistor
e. the torque τ(t) that must be exerted to rotate the loop.

The cheetah is considered the fastest running animal in the world. cheetahs can accelerate to a speed of 20.1 m/s in 2.50 s and can continue to accelerate to reach a top speed of 28.1 m/s. assume the acceleration is constant until the top speed is reached and is zero thereafter.1) starting from a crouched position, how long does it take a cheetah to reach its top speed? (express your answer to three significant figures.) s2) how far does it travel in that time? (express your answer to three significant figures.) m3) if a cheetah sees a rabbit 120 m away, how long will it take to reach the rabbit, assuming the rabbit does not move? (express your answer to three significant figures.)

Auniform electric field exists in the region between two oppositely charged plane parallel plates separated by a distance of 1.60 cm . a proton is released from rest at the surface of the positively charged plate and strikes the surface of the opposite plate in a time interval of 3.20×10-6 s. 1-find the magnitude of the electric field. use 1.60×10-19c for the magnitude of the charge on an electron and 1.67×10-27kg for the mass of a proton 2-find the speed of the proton when it strikes the negatively charged plate
