Blocks A and B of masses mA and mB , respectively, are attached to an ideal pulley to create the Atwood’s machine shown in the figure. Which of the following free-body diagrams could be correct for the blocks when they are released from rest if mB>mA ?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
