Answer:
D. Opening the front door in winter to filter and clean warm ai
Explanation:
All of the following are examples of ways to improve energy efficiency of heating systems, except _______.
A. Closing off rooms that aren’t in use.
B. Frequently cleaning the furnace filter.
C. Fixing cracks in the walls and floor.
D. Opening the front door in winter to filter and clean warm air
for an heating systems it is better to keep the front door shut so that all the heat energy does not escape outside.
when heat energy is within a closed system ,it can still be utilized to keep the inhabitants warm otherwise there will be an exchange with the cold from winter fall outside the air, and the heating system's efficiency will be reduced
I hope you are referring to Newton's Laws of Motion by "Newton's Law".
There are three laws quoted by the great physicist of all time Sir Isaac Newton.
These laws are the building-blocks of the field of the Physics known as Classical Physics or Classical Mechanics.
Law 1. If no force applied externally, then a body in rest will always be in rest and a body in motion will continue to move in a straight line with a uniform velocity.
Law 2. The rate of change of momentum is directly proportional to the force applied and the direction of motion is always in the direction of the force applied.
Law 3. Every action has an equal and opposite reaction.
The Law 1 is also called the law of Inertia.
From the 2nd law, we can derive the equation of force, that is F =m.a (m = mass; a = acceleration)
Ok so basically I’m here for the points cuz I gotta quiz do in 10 minutes sorry
