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
Answer:
beats per second
Explanation:
Number of heart beats =
time taken =
now we have
%
%
now rate of heart beat is defined as number of heart beat per unit of time
so we have
so we have
%
beats per second
