Answer:

D

Explanation:

The specific heat capacity is the heat required to raise the temperature of 1kg of a substance by 1oC. Molar heat capacity of a substance is the heat requiredto raise the temperature of 1mole of a substance by 1oC. Molar heat capacity and specific heat capacity both decreases with increase in atomic weight. Increase in atomic weight also means increase in density of the substance.

A doorknob makes it easier for you to open doors because it is what type of simple machine?
vagabundo [1.1K]

Answer: Wheel and Axle

Both of these work together to form a simple machine. You can't have one without the other.

If you try to turn just the axle itself, then you'll find it takes a lot of work. This is because the inertia of the axle wants to keep the object at rest. Also, you won't have a lot of torque due to the small radius compared to what a doorknob can offer.

Using a doorknob is like putting a (steering) wheel on an axle. This increases the radius and therefore increases the torque. You put in less work into the system and get more out of it.
