In a motor, the RATIO of output work to input work, expressed as a percentage, is the efficiency of the motor.
Answer : Ratio
I would say all of the above
<span>Barometric pressure is just the same as
atmospheric pressure. It is called barometric pressure because the instrument
used to measure is called barometer. It is the pressure exerted by the air at a
certain altitude. Since it is the pressure exerted by the air, it is also known
as the weight of the air above the Earth. Depending on the altitude at which
the measurement is done, barometric or atmospheric pressure varies, but the
barometric pressure at sea level is 1 atm (atmosphere). It is equivalent to
101325 Pa (Pascal), 760 torr, 760 mm Hg and 1.01325 bar.</span>
Instantaneous speed because that is the speed in which the object (the car) is at in a given moment.
The Newman projection gives the view of the molecule. In molecule A the torsional strain and in B steric strain are present because of the gauche methyl group.
<h3>What is a torsional strain?</h3>
The Newman projection depicts the molecules in the head-on view and uses the letters and the lines to represent the molecule. The torsional strain is because of the molecule's resistance to the twisting.
The steric strain is the Vander wall strain that is due to the forced interaction of the molecules separated by covalent bonds resulting in molecular potential energy.
The diagram for the question is attached below.
Therefore, the correct blanks are <u>torsional</u>, <u>steric</u>, and <u>gauche</u>.
