(iii) an air bubble at the bottom of a lake 43.5 m deep has a volume of 1.00 cm. if the temperature at the bot- tom is 5.5°c and at the top 21.0°c, what is the volume of the bubble just before it reaches the surface? 45. (11) a cubic box of volume 3.9 × 10-2 m3 is file with air at atmospheric pressure at 20°c. the box closed and heated to 180°c. what is the net force on each side of the box?

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

He viscosities of several liquids are being compared. all the liquids are poured down a slope with equal path lengths. the liquid with the highest viscosity will

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
