Answer:
B
Explanation:
The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.
Thermal energy is the sum total of the average kinetic energy within the system.
It is mathematically expressed as:
Quantity of energy = mass x specific heat x change in temperature
We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.
Answer:
thermal conductivity = 0.2906 W/m.K
Explanation:
thermal conductivity = 0.168 BTU/h.ft⁰F
1 BTU/h.ft⁰F = 1.7295772056 W/m.k
0.168 BTU/h.ft⁰F = 0.168 * 1.7295772056 W/m.k
0.168 BTU/h.ft⁰F = 0.2906 W/m.k
Lifting the book means that the object gains gravitational potential energy. GPE=mass*gravitational field strength*height,
∴m=GPE/gh, m=25.5/10*1.5=1.7 kg
The motion of an electric<span> charge producing a magnetic field is an essential concept in understanding magnetism. The magnetic moment of an atom can be the result of the electron's spin, which is the </span>electron orbital motion<span> and a change in the </span>orbital<span>motion of the electrons caused by an </span>applied<span> magnetic field.</span>
