Which of the following is not accurate when describing solids? A. Solids are better conductors of heat than liquids B. The amoun
t of pressure exerted by a solid is solely dependent on its mass. C. Solids with many air pockets are good insulators. D. Molecules in solids are closer together than molecules in liquids.
B. The amount of pressure exerted by a solid is solely dependent on its mass.
<h3><u>Explanation</u>;</h3>
Pressure is the force per unit area exerted by a substance on a surface.
<em><u>Solids exerts pressure on surfaces, which does not depend on the mass of the solid, but depends on the area of contact on the solid and the force applied.</u></em>
<em><u>Since pressure refers to force exerted per unit area. Pressure can be increased by either increasing the size of the force or reducing the area over which the force acts.</u></em>
<em><u>A solid with a larger surface area where the force acts will exert less pressure compared to a solid surface with a small area where the force acts. </u></em>
Explanation:when elevator does not move it reads weight of the person . when elevator moves up let apparent weight be F . W acts downwards so net force is F-W
If Earth was twice as far from the sun, the force of gravity attracting the Earth to the sun would be only one-quarter as strong. The correct answer will be C.
