Which statements explain the relationship between photosynthesis and cellular respiration? Check all that apply. The glucose that plants use for energy is made by animals in cellular respiration. Glucose is a reactant in both photosynthesis and cellular respiration. The oxygen released by photosynthesis is breathed in by animals to break down glucose. Carbon dioxide is a product of both photosynthesis and cellular respiration. The carbon dioxide released by animals is used to build glucose in photosynthesis.

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s.t.p.?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
