How do a proton and an electron compare?
a. the proton is farther from the nucleus.
b. they have opposite charges.
c. they are both found in the nucleus.
d. the electron has greater mass.

An object of dimensions 50 cm x 40 cm x 0.20 cm has a mass 60g. find its density in g/cm3 and kg/ m3

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

An object's buoyant force and weight mean the same thing.a. trueb. false
