Answer:
Work done, W = 19.6 J
Explanation:
It is given that,
Mass of the block, m = 5 kg
Speed of the block, v = 10 m/s
The coefficient of kinetic friction between the block and the rough section is 0.2
Distance covered by the block, d = 2 m
As the block passes through the rough part, some of the energy gets lost and this energy is equal to the work done by the kinetic energy.
W = 19.6 J
So, the change in the kinetic energy of the block as it passes through the rough section is 19.6 J. Hence, this is the required solution.
Answer:
a) The equivalent temperature of 2000 ºC is 3632 ºF.
b) The equivalent temperature of 2000 ºC is 4091.67 R.
c) The equivalent temperature of 2000 ºC is 2273.15 K.
d) The equivalent temperature of 2000 ºC is 1600 ºRe.
Explanation:
a) The equivalent temperature on the Fahrenheit scale is defined by the following formula:
(Eq. 1)
Where:
- Temperature, measured in degrees Celsius.
- Temperature, measured in degrees Fahrenheit.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 3632 ºF.
b) From result in a) we determine the equivalent temperature on the Rankine scale by using the following formula:
(Eq. 2)
Where:
- Temperature, measured in degrees Fahrenheit.
- Temperature, measured in Rankine.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 4091.67 R.
c) The equivalent temperature on the absolute scale is calculated by using this expression:
(Eq. 3)
Where:
- Temperature, measured in degrees Celsius.
- Temperature, measured in Kelvin.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 2273.15 K.
d) The equivalent temperature on the Réaumur scale is calculated by applying this expression:
(Eq. 4)
Where:
- Temperature, measured in degrees Celsius.
- Temperature, measured in degrees Réaumur.
If we know that , then the temperature is:
The equivalent temperature of 2000 ºC is 1600 ºRe.
