Answer:
60 km/hour.
Explanation:
We'll begin by calculating the total distance traveled by the car. This is illustrated below:
Total distance traveled = sum of distance between PQRST
Total distance = 10 + 5 + 10 + 5
Total distance = 30 km
Next, we shall convert 30 mins to hour. This can obtained as follow:
Recall:
60 mins = 1 hour
Therefore,
30 mins = 30/60 = 0.5 hour.
Finally, we shall determine the average speed of the car as follow:
Distance = 30 km
Time = 0.5 hour
Speed =?
Speed = distance /time
Speed = 30/0.5
Speed = 60 km/hour
Therefore, the speed of the car is 60 km/hour.
Answer:
spacing is 0.8307 mm
Explanation:
given data
wavelength = 500 nm
interference fringes N = 1.5 mm
wavelength = 640 nm
to find out
spacing between the fringes
solution
we know bright fringe spacing in double slit is express as
w × sinθ = N × wavelength
so angle is
sinθ = N × wavelength / w
and spacing is express as
spacing = d sinθ
and that is = N × (d/w) × wavelength
so
spacing = 1.5 × 360 / 650
so spacing is 0.8307 mm
