Answer:
F = 20.07 μN
Explanation:
given,
intensity of sunlight = 667 W/m²
area of surface = 9.03 m²
speed of light = 3 x 10⁸ m/s
force = ?
we know
force =
force =
F = 20.07 x 10⁻⁶ N
F = 20.07 μN
Answer:
iPod does not use analog signals
Explanation:
Answer:
Explanation:
Average velocity is found in the total displacement experienced in the trip divided by the total time it took to make this trip. If, for the first 2.0 hours, the car travels at 60 km/hr, then in 2.0 hours the car can travel 120 km; if it then travels for 3.0 at 85 km/hr, it can travel 255 km in the same direction. The total time this took was 5.0 hours. So doing the math and rounding correctly by following the rules for the adding and subtracting of sig fig's:
If you do not round when you add, the average velocity is 75 km/hr
The equivalent resistance of the three resistors when connected in parallel is:
Since the three resistors in this problem are identical, we can call R their resistance, and we can rewrite the previous equation as
And since we know the value of the equivalent resistance,
, we can find the value of R:
Now the problem asks us what is the equivalent resistance of the three resistors when they are connected in series. In this case, the equivalent resistance is just the sum of the three resistances, so
