Assuming 100 kw bulb
<span>We'll start by figuring out how much energy in
kilowatt-hours the light bulb uses per year. We multiply how much power it uses
in kilowatts, by the number of hours in a year. That gives 0.1 kW x 8,760 hours
or </span>876 kWh x 9 bulbs = 7884 kWh
The electricity produced by 4 tons x 2460
kWh/ton = 9840 kwh
<span>Since the produced electricity is bigger so it
is enough</span>
Answer:
ill answer........... nvm i can't ur handwriting is dog
Step-by-step explanation:
C)The matter that makes up rocks is never destroyed,but this matter does change form and move from place to place.
To get y - intercept put the value of x =0
so 4y = -3
y= -3/4
First, we find the time spent accelerating:
s = ut + 1/2 at²; u = 0
10 = 1/2 5t²
t = 2 seconds
Velocity at point B:
v = u + at; u = 0, a = 5 m/s², t = 2 s
v = (5)(2) = 10 m/s
Now, the same velocity is at C so we find the time decelerating to 0 in CD
v = u + at, v = 0, u = 10 m/s, a = -4 m/s²
0 = 10 - 4t
t = 2.5 seconds
Total time = time(AB) + time(BC) + time(CD)
20 = 2 + time(BC) + 2.5
time(BC) = 15.5 seconds
Distance = velocity x time
BC = 10 x 15.5
= 155 m
