Suppose you have two blocks, A and B. Both are made of the same material, and B is more massive (heavier) than A. There is a massless string connecting blocks A and B. With your hand, you pull block A to the left. Both blocks speed up as you pull them.. You may assume that both blocks have the same coefficient of kinetic friction with the sliding surface. 1. Which should be the greater force: a. FB-on-A b. FA-on-B2. Draw two separate free body diagrams – one for block A and one for block B. Label the forces in the form "FB-on-A", for example, if the force is exerted by object B and felt by object A.

What term do psychologists use to designate our personal awareness of feelings, sensations, and thoughts?

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
