63 C = _____ 63 K 336 K 210 K 163 K
2 answers:
Answer : The correct option is, 336 K
Explanation :
The conversion used for the temperature from degree Celsius to Kelvin is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in degree celsius is,
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in Kelvin is 336 K.

Answer:
22Ω
Explanation:
Given parameters:
Potential difference = 3.3V
Current = 0.15A
Unknown:
Resistance = ?
Solution:
According to ohm's law, potential difference, current and resistance are related by the expression below;
V = I R
where V is the voltage
I is the current
R is the resistance
3.3 = 0.15 x R
R = = 22Ω
