Answer:
1920watts
Explanation:
P=IV
P = 16 x 120 = 1920 watts
Answer:
2k
Explanation:
100W X 10h = 1000Wh = 1KWh thus cost is 2k
Answer:
= 5.1 W
Explanation:
time (t) = 30 ms = 0.03 s
mass (m) = 560 g = 0.56 kg
initial velocity (U) = 0 m/s
final velocity (V) = 0.74 m/s
power = \frac{work done}{t} = \frac{f x d}{t} = f x v = m x a x v
m x a x v = m x \frac{V-U}{t} x \frac{V + U}{2}
m x \frac{V-U}{t} x \frac{V + U}{2} = 0.56 x \frac{0.74 - 0}{0.03} x \frac{0.74+0}{2}
= 5.1 W
Average speed = (distance traveled) / (time to cover the distance)
= (35 yards) / (3.8 seconds)
= 9.21 yards per second
