A class assignment requires the building of a solar powered car that will travel at least 10 meters in 10 seconds. Each group is given one solar cell for their design.
Which of these would improve the design the most?
Making the size of the car bigger.
Using a thicker axle.
Reducing the mass of the design.
Adding mass to the design.

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.

Arrange the images in order to show how lake-effect snow occurs.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
