<u>Given data:</u>
Voltage (V) = 120 V,
Power (P) = 50.4 Watts,
current flowing (I) = ?
Power is nothing but the rate of doing work. Hence W/t represents electric Power (P).
Electric Power (P) = V.I Watts
This equation can be used to calculate the power consumption by any electrical device that is connected in a circuit.
In the given question, we need to determine the Current flowing through the circuit(bulb).
From the equation,
P = V.I Watts
50.4 = 120 × I
I = 50.4/120
I = 0.42 Amp
<em>Current flowing through the circuit is 0.42 Amperes. </em>

D I think.
Explanation:
It's hard to tell without the short story that was in the lesson this is a hard question to answer. You can delete this if you want.
This question is not complete.
The complete question is as follows:
One problem for humans living in outer space is that they are apparently weightless. One way around this problem is to design a space station that spins about its center at a constant rate. This creates “artificial gravity” at the outside rim of the station. (a) If the diameter of the space station is 800 m, how many revolutions per minute are needed for the “artificial gravity” acceleration to be 9.80m/s2?
Explanation:
a. Using the expression;
T = 2π√R/g
where R = radius of the space = diameter/2
R = 800/2 = 400m
g= acceleration due to gravity = 9.8m/s^2
1/T = number of revolutions per second
T = 2π√R/g
T = 2 x 3.14 x √400/9.8
T = 6.28 x 6.39 = 40.13
1/T = 1/40.13 = 0.025 x 60 = 1.5 revolution/minute
Answer:
The distance between gas species are assumed to be large.
Explanation:
Hello!
In this case, since the ideal gas condition is a hypothetical state of gases at which they are at low pressure and high temperature, because it is assumed the molecules are neither attracted nor repelled by each other, we can infer that the correct statement is "the distance between gas species are assumed to be large" because the low pressure and high temperature ensure the molecules are far away from each other and therefore allowing the ideal equation to be used to model the case, otherwise a rigorous equation of state such as Peng-Robinson, Redlich-Kwong and other should be used to model it as gases actually undergo interaction between their molecules.
Best regards!
Power is equal to work divided by time
