Which of the following processes does not occur during the convective transfer of heat within a container of air? group of answer choices the cooler portion of the air surrounding a warmer part exerts a buoyant force on it. the flow of air molecules results in a flow of heat. as the warmer part of the air moves, it is replaced by cooler air that is subsequently warmed. a continuous flow of warmer and cooler parts of air is established. the volume of a warmed part of the air is reduced and its density increases.

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )

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^.

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.
