Using an example, explain how small atoms are.

The rate of heat conduction out of a window on a winter day is rapid enough to chill the air next to it. To see just how rapidly windows conduct heat, calculate the rate of conduction in watts through a 2.82 m2 window that is 0.

Once the magnet moved closest to the loop in the forward direction, under normal magnet polarity, the approximate magnitude of the induced current shown on the galvanometer was mA.

What happens when a charged insulator is placed near an uncharged metallic object?

Does wve travel faster through glass or air

How do we see an object that isn't luminous?

Scenario A: A ramp is used to lift a refrigerator a height of 12 m with a force of 110 N. The ramp is at an angle of 50° to the ground. Scenario B: A ramp is used to lift a refrigerator a height of 13 m with a force of 120 N.

The sun is 30 degrees above the horizon. it makes a 51 m long shadow of a tall tree. part a how high is the tree?

What can destroy stuff yet does not have any mass

The small piston of a hydraulic lift has a cross-sectional of 3 00 cm2 and its large piston has a cross-sectional area of 200 cm2.

The pressure, temperature and volume of a system change differently during the process of isothermal expansion. Indicate whether each quantity increases, remains constant, or decreases.
