A 5.21 box sits on a ramp that is inclined at 37.8 above the horizontal. The coefficient of kinetic friction between the box and the ramp is 0.29. What horizontal force is required to move the box up the incline with a constant acceleration of 4.00 ?

277. ## physics

A small particle has charge -4.20 and mass 1.10×10−4 . It moves from point , where the electric potential is = 250 , to point , where the electric potential = 740 is greater than the potential at point . The electric force is the only force acting on

278. ## chemistry

Ethanethiol (CH3CH2SH, pKa=10.6) was named the smelliest substance in existence. Draw the equilibrium that forms when ethanethiol is added to a solution buffered at pH 9, and show the relative proportions of all organic species.

279. ## Chemistry(Please check)

What is the hybridization of each carbon in the molecule of ethanol. CH3 = sp3 CH2OH = sp3 I think that the carbons are all sp3 because there are only single bonds in this molecule. Is this correct?

280. ## physics

When the Sun is directly overhead, a hawk dives toward the ground with a constant velocity of 5.20 m/s at 51.5° below the horizontal. Calculate the speed of her shadow on the level ground.

281. ## writing
