A deuteron of mass M is moving at speed v before colliding with an immobile α-particle of mass 2M. The deuteron is deviated 90° from its initial direction. Knowing that the collision is elastic, determine the angle of the trajectory of the α-particle with respect to the deuteron’s initial path.

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared

What is the magnitude of the gravitational force acting on the earth due to the sun?

Aheat engine that operates on a carnot cycle has an efficiency of 0.420 when its low-temperature reservoir is at 10 ∘c.part aby how many degrees celsius must you increase the temperature of the high-temperature reservoir to increase the efficiency to 0.600 if you continue to use the same low-temperature reservoir?
