Ablock of wood weighing 25 n is subrnerged under water. if the net force on the wood is 5 n upward, how much buoyant force is acting on the wood?
a) 30 n upward
b) 20 n upward
c) 5 n upward
d) 25 n downward

A) 30 N upward

Explanation:

There are two forces on the block: buoyant force up and weight down.  The net force is 5 N up, so:

5 N = B − W

The weight is 25 N so:

5 N = B − 25 N

B = 30 N

The buoyant force is 30 N up.

this isn't the answer but they're the graphs

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
