Answer:
a) Pi = 3200 w
b) Pe = 640 w
Explanation:
Solar radiation is 800 w/m²
a) Area of solar panel is 4 m²
Then Power Incident is:
Pi = Solar radiation x Area of solar panel array , then
Pi = 800 w/m² * 4 m²
Pi = 3200 w or Pi = 3.2 Kw
b) Solar panels efficiency is 20%
Electricity production: Pe
Pe = Pi * η where η is efficiency η = 20 % η = 0,2
Pe = 3200 w * 0,2
Pe = 640 w or Pe = 0,640 Kw
The intensity of a radioactive sample is commonly measured using a geiger counter. A geiger counter is known as a radiation detector, and it can detect a broad range of ionizing alpha and beta particles, as well as gamma rays and x-rays that are being emitted.
G: V=120v and I=.75amps
U: R=?
S: To fins the resistance of the lightbulb you’d have V divided into I so,
S: 120/.75 = Therefore the resistance is 160ohm
