Draw free-body diagrams showing the weight and normal forces on a laundry basket in each of the following situations: a. at rest on a horizontal surface
b. at rest on a ramp inclined 12 degrees above the horizontal
c. at rest on a ramp inclined 25 degrees above the horizontal
d. at rest on a ramp inclined 45 degrees above the horizontal

Work = force × a. work b. energy c. distance d. momentum

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
