Answer:
0.08 ampere
Explanation:
Power = voltage x current
W = v x I
Given
Power = 10.0 w
V = 120v
I = ?
Therefore
10.0 = 120 x I
Divide both sides by by 120
10.0/120 = 120/120 x I
0.08 = I
I = 0.08 ampere
Answer:
I will specify a value of 0.009T for the alternator’s magnetic field
Explanation:
E_peak = 14 V
d = 10cm = 0.1m, so r = 0.1/2 =0.05m
N = 250 turns
f = 1200rpm = (1200rp/m x 1m/60sec) = 20 revolutions per second
At peak performance, peak voltage is given by the equation;
E_peak = NABω
Let's make the magnetic field B the subject;
B = E_peak/(NAω)
Now we know that ω = 2πf
Thus, ω = 2π x 20 revs/s = 125.664 revs/s.
Let's convert it to the standard unit which is rad/s.
1 rev/s = 6.283 rad/s
Thus, 125.664 revs/s = 125.664 x 6.283 = 789.55 rad/s
Area (A) = πr² = π x 0.05² = 0.007854 m²
Thus, plugging in the relevant values to get;
B = 14/[(250 x 0.007854 x 789.55)] = 0.009T
Answer:
Hey
on August 6, 1945, the atomic bomb was released. the only remains of the poor people in Hiroshima were the shadows of the last place they stood.
The energy that was released by the atomic bomb was transferred by nuclear fission (The processes at which atoms split and give off energy).
In the core of the sun, the process is different from that of fission. it is called nuclear fusion (the process in which atoms [of hydrogen] are smashed together into helium and release tremendous amounts of energy).

Hope it helped
It’s not arrested because if you look closer it’s plug walk I don’t even understand how it talk tho
