Standard physical quantity is used for measurement because they are the components of a given body that can be measured using physical measuring tools and are less prone to errors; weighing balance, Rule are some of the measuring tools

Physical and non-physical quantities can be measured but the measurement carried out on physical quantities are less prone to error, when compared to non-physical measurement. Non-physical measurements are carried out using the Ordinal scale ( more or less an estimate measurement )

Examples of physical quantities includes : mass , height , temperature  while Non-physical quantities includes : anger , personal feelings  e.t.c

Hence the reason why standard physical quantities are used is because they are measured using measuring tools and are less prone to error

: The maximum theoretical efficiency of a Carnot engine operating between reservoirs at the steam point and at room temperature
Hunter-Best [27]

Answer:

The value is   \eta  =  0.2145  or  21.45%

Explanation:

From the question we are told that

    The first reservoir is at steam point  T_s =  100^o C =  100 + 273 = 373 \ K  

    The  second reservoir is at room temperature T_r  =  20^o C = 293 \ K

Generally the  maximum theoretical efficiency of a Carnot engine  is mathematically evaluated as

     \eta  =  1- \frac{T_r}{T_s}

=>    1 - \frac{ 293}{373}

=>    \eta  =  0.2145

Sam is riding his bike in the park when he sees a soccer ball rolling toward him. He applies his brakes to slow down. Once he st
nlexa [21]

When Sam presses the brake lever, a pair of rubber shoes  clamps onto the metal inner rim of the front and back wheels. As the brake shoes rub  against the wheels, friction is caused and  the kinetic energy possessed by the vehicle is converted into heat which slows down the vehicle.

Apply the law of conservation of energy and describe the energy transformations that occur as you coast down a long hill on a bi
m_a_m_a [10]
As you coast down a long hill on your bicycle, potential energy from your height is converted to kinetic energy as you and your bike are pulled downward by gravity along the slope of the hill. While there is air resistance and friction slowing you down by a little bit, your speed increases gradually until you apply the brakes, causing enough friction to slow yourself and the bike to a stop at the bottom.

A roller coaster will have higher kinetic energy at the lower hill because it will have already been moving as opposed to the initial hill. But I'm not one hundred percent certain. You can always google this stuff, but I do know for sure that at the first hill, the roller coaster will have higher potential energy.
Hope this helps!
