The total number of lamps is mathematically given as
N=24
<h3>What is the t
otal number of
lamps?</h3>
Question Parameters:
How many 60-watt lamps could be connected in parallel on a 15-amp, 120-volt
Generally, the equation for the Power is mathematically given as
P=IV
Therefore
I=P/v
I=60/120
I=0.5A
Since the system does not exceed 80% of the rating
NI=I'(0.8)
N=15*0.8/0.5
N=24
In conclusion, the total number of lamps is
N=24

Explanation:
Fossil Fuels:
Coal and Oil
How they are formed:
Coal is formed from big plants, from a long time ago. When the big plants died, they formed layers at the bottom of swamps and the dirt began to pile up and it formed Coal.
Oil is a fossil fuel that has been formed from a large amount tiny plants and animals such as algae and zooplankton.
Answer:
E = 307667 N/C
Explanation:
Since the object's mass is 1 g, then its weight in newtons is 0.001 * 9.8 = 0.0098 N.
This weight should have the same magnitude of the vertical component of the tension T of the string (T * cos(37)) so we can find the magnitude of the tension T via:
0.0098 N = T * cos(37)
then T = 0.0098/cos(37) N = 0.01227 N
Knowing the tension's magnitude, we can find its horizontal component:
T * sin(37) = 0.007384 N
and now we can obtain the value of the electric field since we know the charge of the ball to be: -2.4 * 10^(-8) C:
0.007384 N = E * 2.4 * 10^(-8) C
Then E = 0.007384/2.4 * 10^(-8) N/C
E = 307667 N/C
