Answer : 2446 years.
Explanation :
Length of semi major axis is,
According to Kepler's third law, square of time period of an orbit is directly proportional to the cube of the semi major axis.
i.e
where G is gravitational constant
M is mass of sun,
So,
since,
So, orbital period is approximately 2446 years.
Answer:
Explanation:
Given data
length=100mm
Diameter=5mm
Thermal conductivity=5 W/m.K
Power=50 W
Temperature=25°C
The temperature of heater surface follows from the rate equation written as:
Where S can be estimated from the conduction shape factor for a vertical cylinder in semi infinite medium
Substitute the given values
The temperature of heater is then:
The temperature reached by the heater when dissipating 50 W with the surface of the block at a temperature of 25°C.
