• Air in a cylinder is compressed to one-tenth of its original volume without change in temperature. What happens to its pressure? Imagine now that a valve is opened in order to restore the initial pressure value. What percentage of the molecules have escaped?
• Consider a 40,000 km steel pipe in the shape of a ring that fits snugly all around the circumference of the Earth. We are heating now the ring so its temperature increased by 1 degree C. Now, the pipe will no longer be snug. How high the ring will now stand above ground level? (Make as many simplifications as necessary). Data: Coefficient of linear expansion for steel is 11*10-6 /degree C. This means, for example, that a 1-meter bar of steel that increases its temperature by 1 degree C will expand 11*10-6 meters (11 micrometers)
• Farmers resort to spraying fruit trees with water before a frost to protect the fruit from freezing. Using the concepts learned in this module, discuss why this does or does not work.
• An electric fan not only does not decrease the temperature of the air, but it actually increases air temperature. How can you then explain that you are cooled by a fan
The object has a charge of +24.0 μC and the instrument indicates that the electric force exerted on it is 44.0 μN, due east. What are the magnitude and direction of the electr
A couple of astronauts agree to rendezvous in space after hours. Their plan is to let gravity bring them together. She has a mass of 60.0 kg and he a mass of 76.0 kg , and t
The image of a tree on a 35 millimeter color slide is 1.9 millimeter high. It is to be projected onto a screen 10 meter from the slide, and is to appear 370 millimeter high.
A 2.5 kg object is attached to a horizontal spring of force constant k = 4.1 kN/m. The spring is stretched 10 cm from equilibrium and released. Find the maximum acceleration
A 2.00 kg piece of wood slides on the surface shown in the accompanying figure. Where will the wood eventually come to rest? How much work is done by friction by the time the
An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner's 2 T field with his fingers pointing in the direction of the field. O
