Answer:
If an object has a fast velocity, the dots on a ticker tape diagram will be far apart.
A). Convection is heating the soup in the pot.
When you stick the spoon into the hot soup,
conduction heats the spoon all the way up to the end.
b). Water conducts heat a little bit.
But convection is much more responsible for the
uniform distribution of temperature in the kiddie pool.
c). The heat from the metal bench conducts directly
to the buttus epidermis when you sit on it.
d). You feel the heat on your face ... but not on the back of your
neck ... on account of radiation from the fire and the hot grill.
Answer:
The cat will have <span>36J</span> of kinetic energy.
For part a)
Since the conical surface is not exposed to the radiation coming from the walls only from the circular plate and assuming steady state, the temperature of the conical surface is also equal to the temperature of the circular plate. T2 = 600 K
For part b)
To maintain the temperature of the circular plate, the power required would be calculated using:
Q = Aσ(T₁⁴ - Tw⁴)
Q = π(500x10^-3)²/4 (5.67x10^-8)(600⁴ - 300⁴)
Q = 5410.65 W
