A roller coaster is traveling on a frictionless track with a speed of 2 m/s at point A and continue to move on a different path as shown on the diagram, and stops at a maximum height at point D. Calculate its speed (in m/s) as it passes point C

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
