When two people come in contact or when contact occurs with an item from the crime scene, the possibility exists that a fiber transfer will take place. This does not mean that a fiber transfer will always take place. Certain types of fabric do not shed well (donor garments), and some fabrics do not hold fibers well (recipient garments). The construction and fiber composition of the fabric, the duration and force of contact, and the condition of the garment with regard to damage are important considerations.
Hope this helps.
Answer: 2.13 × 10^-4 A
Explanation:
Given that the RLC circuit has a resistance R = 200 Ω and an inductance L = 15 mH.
Its oscillation frequency F = 7000 Hz
The initial current I = 25 mA = 25/1000 or 25 × 10^-3 A
Since there is no charge on the capacitor, the current after complete 5 circle will be achieved by using the formula in the attached file.
Please find the attached file for the remaining explanation for the solution.
<h3>160 W</h3>
If the temperature is doubled to 2t, the rate at which it will now radiate is 160 W.
<h3>What is meant by emissivity?</h3>
- The ability of a substance to reflect heat radiation from its surface is measured by its emissivity.
- Thermal radiation is a type of electromagnetic radiation that includes infrared radiation, which the human eye cannot perceive, as well as visible radiation (light).
- According to the Stefan-Boltzmann law, emissivity is the quantitative comparison between the thermal radiation of a surface and that of an ideal black surface at a given temperature.
- Between 0 and 1 is the ratio's range.
<h3>What is energy radiation?</h3>
- The emissivity of a substance is a measurement of how well it reflects heat radiation from its surface.
- Two elements that affect power dissipation in the form of radiation are the material's surface emissivity and the temperature difference between the chip surface and the surrounding air.

Answer:
When put into steam
Explanation:
When a certain amount of steam at boiling temperature condenses (turning into water), the amount of heat released is

where in this case
m = 25.0 g = 0.025 kg is the mass of steam at 100.0°C
is the latent heat of vaporization of water
So,

Instead, the amount of heat released when the water at 100.0°C is cooled down to 34.0°C is given by

where
m = 25.0 g = 0.025 kg is the mass of water
is the specific heat of water
is the change in temperature
Therefore,

Since
, we can say that your hand will burn more in the first case.
