-6.4x10⁻¹⁹ C
The fundamental charge of an electron is -1.60x10⁻¹⁹ C, meaning that each electron has its specific charge. In a sample containing multiple electrons, the total charge will be a multiple of the fundamental charge, based on the electron count. Therefore, for an oil droplet with four electrons, the total charge equates to four times the elementary charge:
4*(-1.60x10⁻¹⁹) C = -6.4x10⁻¹⁹ C
The volume of the body remains unchanged at the beginning of the experiment. The volume stays the same initially because it does not fluctuate unless there is a temperature change. When the temperature increases, molecules begin to expand, resulting in a volume increase, whereas a decrease in temperature causes molecules to contract, leading to a reduction in volume. Thus, we conclude that volume is influenced by temperature.
Answer:
Yes, the food can be served.
Explanation:
The food's serving temperature is at 146°F
- Per FDA (U.S. Food and Drug Administration) guidelines, hot foods must remain at an internal temperature of 140°F or above.
- This temperature is essential to keep bacteria at bay and prevent food spoilage.
- Dishes involving eggs, like quiches and soufflés, should be served at a minimum temperature of 165°F
<pSince the serving temperature of 146°F exceeds 140°F (the minimum required), the food is safe to serve.
