Answer:
Capital of Australia is Canberra
Answer:
A. elevation
Explanation:
The elevation is the factor that influences the variety of temperatures within both the Rocky Mountains and the Himalayan Mountains because, with elevation, the temperature reduces on the mountain. at the bottom of the mount the temperature is milder while at the head of the mountain, the temperature is cooler and very low. So we can say that altitude is the principal factor in the variety of temperatures in mountains.
Answer:
D. after 3 minutes, Sam is 40 meters from the dock.
Explanation:
For an input of 3, the function will produce a value of 40. That is in 3 minutes, the boat would have covered a distance of 40meters.
We can solve this problem using the given graph.
We know that this is a distance - time graph. The slope of this graph gives the value of the speed of the boat.
- From the time - axis, mark point 3 which corresponds to the input given.
- Trace it up to the point where it coincides with the graph.
- Then find the distance axis value of the point.
- Doing this yield 40m
So, in 3 minutes, Sam will row a distance of 40m.
Answer:
Option (C)
Explanation:
The angular resolution formula,
Sin A= 0.25 (Wavelength ÷ Diameter)
where, wavelength is taken in micrometer and diameter is in meter.
Here, wavelength (W)= 650 nm = 0.65 μm (converting nanometer into micrometer)
Diameter= 2 m
now, according to the formula,
![\sin A=0.25\times [\dfrac{wavelength}{diameter}]\\\\\sin A=0.25\times \dfrac{0.65\ \mu m}{2\ m}\\\\\sin A=0.08125''\\\\\sin A\approx 0.082''](https://tex.z-dn.net/?f=%5Csin%20A%3D0.25%5Ctimes%20%5B%5Cdfrac%7Bwavelength%7D%7Bdiameter%7D%5D%5C%5C%5C%5C%5Csin%20A%3D0.25%5Ctimes%20%5Cdfrac%7B0.65%5C%20%5Cmu%20m%7D%7B2%5C%20m%7D%5C%5C%5C%5C%5Csin%20A%3D0.08125%27%27%5C%5C%5C%5C%5Csin%20A%5Capprox%200.082%27%27)
Thus, the correct answer is option (C) i.e. 0.082 arc second.
