Answer:
<h2>1.5 ohms</h2>
Explanation:
Power is expressed as P = V²/R
R = resistance
V = supplied voltage
Given P = 600W and V = 30V
R = V²/P
R = 30²/600
R = 900/600
R = 1.5ohms
magnitude of its resistance is 1.5ohms
Answer:
5.63 atm
Explanation:
P1 = 5 atm
P2 = ?
T1 = 5 °C = 5 + 273 = 278 K
T2 = 40 °C = 273 + 40 = 313 K
Let the pressure is P2.
Use
Pressure is directly proportional to the absolute temperature as the volume remains constant.
P2 = 5.63 atm
Thus, the pressure is 5.63 atm.
