17. Given the following see saw, using Newton's Second law for rotation: a polar bear is balancing on a seesaw at a position of = 4 m. The fulcrum is shifted to a position of = 22 m. The seesaw has a mass of = 180 kg, and its center of mass is at a position of = 49 m.

Find the mass of the polar bear.

Sketch and label the graphs and equations for a series RCcircuit,powered by a battery with voltage, V and a switch to startthecurrent flow at t=0. Write equations for q(t) and I(t). [q(t)and I(t) are the vertical axis and t is the horizontalaxis]

q(t) = _______________

I(t) = _______________

Q= P E = mgh

(5000m³ * 1000/1m^3 kg)*(9.8 m/s^2)(50) <---water

S = Q/T = (2.45*10^9 J)/293K = 8360 KT/K

Q=mCΔT

Find the change in temperature in water
