The bottom of a box has a surface area of 58.8 cm2. the mass of the box is 12.0 kg. acceleration due to gravity at sea level is 9.80 m/s2. what is the pressure exerted by the box where it rests?
2.00 pa
72.0 pa
2.00 x 10^4 pa
0.500 pa

Pressure is defined as force per unit area. It  is the force applied perpendicular to the surface of an object per unit area. We calculate as follows:

P = F / A 
P = ma / A
P = (12)(9.80) / 58.8
P = 2 Pa

Therefore, the first option is the answer.

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

The answer is 12, for the points
