Which of the following best describes Prufrock’s internal conflict in the poem?

A circular window 30 cm in diameter in a submarine can withstand a  net maximum force of 5.20 × 10 5 N without damage. What is the maximum depth in a fresh-water lake to which the submarine can go without damaging the window? The density of fresh water is 1000 kg/m 3.

When a car of mass   accelerates from 10.0 m/s to some final speed, 4.00  × 10 5 J of work are done. Find this final speed.

During a hockey game, a puck is given an initial speed of 10 m/s. It slides 100 m on the horizontal ice before it stops due to friction. What is the coefficient of kinetic friction between the puck and the ice?

What is the mass of an object that experiences a gravitational force of 685 N near Earth’s surface where  g = 9.80 m/s 2?

A window glass that is 0.5 cm thick has dimensions of 3 m by 1.5 m. The thermal conductivity of this glass is 0.8 W/m ∙ K. If the outside surface of the glass is at -10°C and the inside surface is at 20°C, how much heat flows through the window in every hour?

A force of   stretches a very light ideal spring   from equilibrium. What is the force constant (spring constant) of the spring?

How much heat is required to raise the temperature of a 0.225 kg lead ball from 15.0°C to 35.0°C? The specific heat of lead is 128 J/kg ∙ K.

A 500-N weight sits on the small piston of a hydraulic machine. The small piston has an area of 1.0 cm 2. If the large piston has an area of 40 cm 2, how much weight can the large piston support? Assume the pistons each have negligible weight.

A mechanic lifts the front of a car with a jack. Find the mechanical advantage if a force of   on the jack handle lifts the car that weighs 960lb.
