The <span>flow of how a cold pack works on a sprained ankle is based on the second law of thermodynamics which states that energy will flow from a higher to a lower temperature. So your body heat will flow to the cold pack in which you will feel the coldness of the pack.</span>
Infinite campus has two options for one it’s the instruction
The correct answer is
<span>B) UV waves are higher frequency and carry more energy.
In fact, UV waves have higher frequency than visible light. For comparison, visible light has frequency in the range 430-770 THz (</span>
)<span>, while ultraviolets (UV) have frequency higher than these values (at the order of 1 PHz, </span>
).
The energy of electromagnetic radiation is proportional to its frequency, according to the equation
where h is the Planck constant and f is the frequency. We see that the higher the frequency, the greater the energy, so UV waves carry more energy than visible light.
Answer: The mass of an object can be calculated in a number of different ways: mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume. mass=force÷acceleration (m=F/a).
Answer:
"2Ω" is the net resistance in the circuit.
Explanation:
The given resistors are:
R1 = 3Ω
R2 = 6Ω
The net resistance will be:
