Answer:
Frying an Egg
Explanation:
When chemical bonds are broken or formed, new particles are created. Therefore, frying an egg is a chemical change because it results in the formation of new particles.
Answer: resistance = 220 ohms
Explanation: given that
Power P = 55W
Current I = 0.5A
Potential difference V = 110V,
Using the formula
P = IV =V^2/R
55 = 110^2/R
R = 12100/ 55
R = 220 ohms
