Answer:
No, the eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation
Reasons:
-Thermal energy is being transferred by conduction.
-Radiation transfers thermal energy by electromagnetic waves.
-Radiation does not transfer thermal energy by direct contact.
Radiation heat transfer is a process where heatwaves are emitted that may be absorbed, reflected, or transmitted through a colder "body". Sun heats the earth by electromagnetic waves. The sun does not come in physical contact with the Earth to transfer heat. (In my opinion, the Earth touching the sun would not be on my to-do list.)

Answer:
118 N
Explanation:
Given mass of the block, m = 4.00kg.
The acceleration of the elevator, a = 3.0 m/s^2.
As elevotar attaced with spring scale and accelerating upward
(block and elevator), so total force
Here, mg is the weight of the block downward direction.
or
substitute the given value, we get
= 117.6 N = 118 N.
Thus, the reading on the spring scale to 3 significant figures is 118 N.
Answer:
D).
Explanation:
As we know that temperature scale is linear so we will have
now we have
so the relation between two scales is given as
now we know that in kelvin scale the absolute temperature is 600 K
so now we have
so correct answer is
D).
