Answer:
D. 1
Explanation:
I believe this is the answer
B. because it's kind of like a fulcrum.
Answer:
The types of energy is bond breaking and bond forming in chemical energy.
Explanation:
During Chemical reaction energy is required either for breaking up bonds in case of reactants and building bonds to form products.
The chemical reaction in which energy is released is called exothermic reactions, which is released due to making up the bonds.
The chemical reaction in which energy is absorbed is called endothermic reactions, in which energy is absorbed for breaking up the bonds.
Explanation:
Given parameters:
Power of the toaster = 600W
Voltage = 120V
Unknown:
Current = ?
Resistance = ?
Solution:
The power in the circuit is related to resistance and current using the expression below;
P = IV
P =
P is the power
I is the current
V is the voltage
R is the resistance
To find the current;
I = = = 5A
Now, resistance;
V² = PR
R = = = 24ohms
Answer:
The π is from the initial formula of period T=2π/omega
