Answer:
110V
Explanation:
Given parameters:
Current in the lightbulb = 0.5A
Resistance = 220Ω
Unknown:
Voltage = ?
Solution:
To solve this problem, we apply the equation derived from ohm's law;
V = IR
So,
V = 0.5 x 220 = 110V
Answer:
1& 4
Explanation:
1. The average kinetic energy of the particles in a substance determines the substance's temperature.
4. How fast a substance's particles are moving determines how hot or cold the substance is.
Yes, I do think it’s possible because if viruses spread, (like corona), then it could definitley evolve into something worse than a sickness.
Calcium forms an ionic bond to iodine and forms calcium iodide (CaI2). The calcium atom gives away 2 of its valence electrons, one to each of the 2 iodine atoms thus forming the ionic bond.
CH4 - no lone pairs
HCl - 3 lone pairs
H2O - 2 lone pairs
NH3 - 1 lone pair (answer)
