What is the net work done (in J) on the cart?

Consider two containers with the same volume and temperature. Container One holds “dry” air–a mixture of nitrogen and oxygen. Container Two holds “moist” air. The “moist” air has the same ratio of nitrogen to oxygen molecules, but also contains water vapor. According to the ideal gas law, if the pressures are equal, the weight of the gas in Container One will be:

One way to heat a gas is to compress it. A gas at 3.0 atm at 27°C is compressed to three tenths of its original volume, and it reaches 35 atm pressure. What is its new temperature in degrees Celsius?

Which one of the balls hits the ground first?

A hanging weight of mass 9.0-kg is connected by an ideal string going over a zero-mass pulley to a flat 5.0-kg block sliding on a flat table. If the coefficient of sliding (kinetic) friction is 0.19 and the contact surface is 0.36 m2, find the tension in the string (in Newtons).

Which nerve is stimulated when the tip of the tongue feels pain from hot soup?

A miniature, spring-loaded, radio-controlled gun is mounted on an air puck. The gun’s bullet has a mass of 6.00 g, and the gun and puck have a combined mass of 130 g. With the system initially at rest, the radio-controlled trigger releases the bullet, causing the puck and empty gun to move with a speed of 0.500 m/s. Of the total kinetic energy of the gun-puck-bullet system, what percentage is in the bullet?

Which of the cranial nerves are purely sensory?

Parasympathetic innervation to the sublingual salivary gland is supplied by cranial nerve _____.

The central nervous system is made up of the brain and the spinal cord.
