B) It is conduction because the egg is touching the pan.
C) It is convection because you put oil in a frying pan to cook in it.
D) It is convection because you can feel the heat a few inches away from the pan.
Answer: Option (B) is the correct answer.
Explanation:
A process in which transfer of heat occurring when one object touches another object is known as conduction.
For example, when a pan is heated and then an egg is placed over the pan. Then there will be transfer of heat from pan towards the egg.
As a result, the egg gets cooked because the egg was touching the pan.
Hence, we can conclude that it is conduction because the egg is touching the pan.
Heat transfer is used to fry an egg in a pan, It is conduction because the egg is touching the pan. Hence the correct option is option (B).
When frying an egg in a pan, the primary mode of heat transfer is conduction. Conduction is the transfer of heat through direct contact between two objects or substances.
The pan is heated on a stovetop or a heat source, which causes the pan to become hot. When the egg is placed in the pan, the heat from the pan is transferred to the egg through the process of conduction.
Option A suggests that it is conduction because the egg gets cooked, but this answer does not explain the specific mechanism of heat transfer involved.
Option C mentions convection because oil is used in frying. While oil can enhance the cooking process, convection is not the primary mode of heat transfer in this scenario.
Option D states it is convection because you can feel the heat a few inches away from the pan.
Therefore, option B is the correct answer, as it correctly identifies that the heat transfer involved in frying an egg in a pan is conduction because the egg is touching the pan.

Calculate the coefficient of kinetic friction between the box and the floor. [Show all work, including
the equation and substitution with units]
The coefficient of kinetic friction between the box and the floor will be .
Further Explanation:
Given:
The mass of the box is .
The force applied on the box is .
The constant velocity at which the box moves is .
Concept:
The box is pushed on the rough floor and due to this; the box will experience a friction force acting in the direction opposite to the motion of the box.
Since the box moves with a constant velocity of , the acceleration of the box will be considered as zero.
From Newton’s second law of motion, as the acceleration of the box is zero, the net force acting on the box is zero.
The free-body diagram of the box moving on the rough floor is as shown in figure attached below.
From the above explanation, in order to make the net force zero, the friction acting on the box should be equal to the force applied on the box.
The friction force acting on the bxlock is:
Substitute the value of friction force in the above expression.
Thus, the coefficient of kinetic friction between the box and the floor will be .

The speed a spherical raindrop would achieve falling from 3950 m in the absence of air drag is calculated by firstly finding the time it takes for the raindrop to fall this distance using equations of motion, and then using this time in the equation for final velocity. The calculated speed is approximately 2785.30 m/s.
To calculate the speed a spherical raindrop would achieve falling from 3950 m in the absence of air drag, we must recall the equations of motion. The relevant equation here is Final velocity (v) = Initial velocity (u) + Acceleration (gravity, g) * time (t). However, since initial velocity (u) is 0 (when the drop starts falling, it's stationary), the equation simplifies to Final velocity (v) = g * t.
In free fall, a body accelerates under gravity (approximated as 9.81 m/s^2). In terms of time, difficulties arise because we don't know exactly when the raindrop will hit the ground. We can, however, calculate the time it would take for the raindrop to fall 3950 m by rearranging the equation distance (s) = ut + 0.5 * g * t^2 to solve for time. Removing (u), for the reasons explained earlier, we have the equation s = 0.5 * g * t^2. Solving this for time gives t = sqrt(s / (0.5 * g)). Substituting the given fall distance for s we get t = sqrt(3950 / (0.5 * 9.81)) or approximately 284.10 seconds.
Finally, we use this calculated time in our simplified velocity equation which gives v = g * t or 9.81 * 284.10, which equals approximately 2785.30 m/s.
