The point of science is to disprove wrong theories, and continue our knowledge forward that way. it's a lot easier to disprove something than to prove something as a rule has to fail once to be wrong, while you would have to prove and show that the rule works on every possible scenario for it to be proven, which is impossible. as such, a scientist should question current theories for faults, and confirm ( not prove) or disprove them.
I am not 100% sure but i think it is true.
I say 1 it seems the most accurate
Answer:
88 Watts
Explanation:
From the question given above, the following data were obtained:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = IV....... (1)
From ohm's law,
V = IR ........ (2)
Substitute the value of V in equation (2) into equation (1)
P = IV
V = IR
P = I(IR)
P = I²R
With the above formula (i.e P = I²R), we can obtain the power lost to heat as follow:
Resistance (R) = 0.22 Ohm
Current (I) = 20 A
Power (P) =.?
P = I²R
P = 20² × 0.22
P = 400 × 0.22
P = 88 Watts
Thus, the power lost to heat is 88 Watts.
Answer:
I believe it would be C ? my apologies if I'm wrong.
