Suppose you are completely clothed in white and your clothes have an emissivity 0.200, a surface temperature of 10C and a surface area of 1.6 m2. What is the net rate of heat transfer if you are standing in the shade and the surroundings are at -200C

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

explanation:

newton's third law, for every action there is an equal and opposite reaction.

iron would move it is magnetic there is a mag field around the current in the wire

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)

explanation:
