Answer:
D
Explanation:
you can catch it, rolling against a surface can slow it and when you throw it in the air, gravity will slow it down until it drops
The potential difference between the two points if the work done on the charge is +3.4×10^7 joules would be A. 10volts.
Answer:
Option B: Increase the voltage, while keeping the resistance constant.
Explanation:
Current is directly proportional to voltage, but indirectly proportional to resistance.
The wavelength of a wave (λ) is given by λ
where c is the wave speed and f is the frequency
Answer:
Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.
Convection is the heat transfer by the macroscopic movement of a fluid. This type of transfer takes place in a forced-air furnace and in weather systems, for example.
Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of Earth by the Sun. A less obvious example is thermal radiation from the human body. I hope this helps you
