When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline called a longshore current. When a wave breaks at a steep angle on a beach the longshore current in velocity. A wave with a wider breaking angle and lower wave height the longshore current’s velocity.

A) increases, increases

B) decreases, decreases

C) decreases, increases

D) increases, decreases

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
