The magnitude of each force is 259 n, the force on the right is applied at an angle 33◦ and the mass of the block is 20 kg. the coefficient of friction is 0.239. the acceleration of gravity is 9.8 m/s 2 . 20 kg µ = 0.239 259 n 33◦ 259 n what is the magnitude of the resulting acceleration? answer in units of m/s 2 .

The vapour pressure of benzene is 53.3 kpa at 60.6 °c, but it fell to 51.5 kpa when 19.0 g of a non-volatile organic compound was dissolved in 500 g of benzene. calculate the molar mass of the compound.

Why are nonmetals more likely to react with eachother by sharing electrons

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
