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.
Answer:
Torque on the coil will be ZERO
Explanation:
As we know that the magnetic moment of the closed current carrying coil is always along its axis and it is given as
now we know that magnetic field is also along the axis of the coil so here as we know the equation of torque given as
so we have
Answer:
The ratio of forces is 22 : 3.
Explanation:
Case I:
initial velocity, u = 35 mph
final velocity, v = 0
time, t = 15 ms
Case II:
initial velocity, u = 35 mph
final velocity, v = 0
time, t' = 110 ms
let the mass is m.
According to the Newton's second law, the force is given by the rate of change of momentum.
So
