Explanation:
There's a massive amount, just think of anything everyday. Like a table on the floor, or when your walking around and putting pressure on the floor. When you squeeze something which is solid. Anything like that will do.
Answer:
a) three times greater
Explanation:
Remember the heat capacity is the necessary heat to increase the temperature 1 ºC to an specific mass of the substance, in this case since the water and the metal have the same mass, is easier to compare just the neccesary heat.
Since water increases 20 ºC and the metal 60 ºC, it was neccesary 3 times of the quantity of heat to the same amount of mass of the two different susbtances.

The pair of equal forces that pull a planet and the Sun
toward each other are gravitational forces.
1.) Power, P = V²/R = 800²/45 = 4.5 W (A).
2.) Six Resistors in Series.
R = R1 + R2 + R3 + R4 + R5 + R6, Since R is the same, R = 20
R total = 6*20 = 120 (D)
3.) It is the current. Series connection is to evaluate current. (B)
