Bert is standing on a ladder picking apples in his father's orchard. As he pulls each apple off the tree, he tosses it into a basket that sits on the ground 2.5 m below at a horizontal distance of 1.9 m from Bert. How fast must Bert throw the apples (horizontally) in order...

Adding 1.530x10^3 J of electrical energy to a constant-pressure calorimeter changes the water temperature from 20.50C to 21.85C. When 1.75g of a solid salt is dissolved in the water, the temperature falls from 21.85C to 21.44C. Find the value of qp for the solution process.

A hotair balloonist, rising vertically with a constant speed of 5.00 m/s, releases a sadndbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. a. compute the position and velocity of the sandbag at .25...

Okay. Thank you for your help

Physics
During 200 meter and 400 meter races, runners must stay in lanes as they go around a curved part of the track. If runners in two different lanes have exactly the same speed, will they also have exactly the same centripetal acceleration as they go around a curve? Explain.

Chemistry
How many types of stoichiometry are there? Can you list them? Thanks I appreciate it!
