If two point sources of light are being imaged by this telescope, what is the maximum wavelength λ at which the two can be resol
Alex

This question is incomplete.Here is complete one

Consider a telescope with a small circular aperture of diameter 2.0 centimeters. If two point sources of light are being imaged by this telescope, what is the maximum wavelength (lambda) at which the two can be resolved if their angular separation is 3.0x10^-5 radians? Express your answer in nanometers

Answer:

λ =492nm

Explanation:

Given Data

diameter=2.0 cm

angular separation=3.0x10^-5 radians

λ=?

Solution

sin(theta) = 1.22 x λ /D

λ=(0.02×sin(3.0×10⁻⁵))/1.22

λ=492nm

The Nardo ring is a circular test track for cars. It has a circumference of 12.5 km. Cars travel around the track at a constant
KIM [24]

Answer: 50 km, 0, 27.78 m/s

Explanation:

Given

Circumference of the track is 12.5\ km

Speed of car is 100\ km/h

Car drives for 30\ \text{minute}\ or\ 0.5\ hr

(a)Distance traveled is

\Rightarrow D=100\times 0.5\\\Rightarrow D=50\ km

(b)displacement of the car

It can be observed that 12.5 is a multiple of 50, that is, 50 km can be interpreted as 4 complete rounds of the track.

Therefore, the displacement of the car is zero.

(c)To convert kmph to m/s, multiply the entity by \frac{5}{18}

\Rightarrow 100\times \dfrac{5}{18}\\\\\Rightarrow 27.78\ m/s

Viewed from Earth, how does the moon's appearance change during the first week ?
slega [8]
We start to see more off the dark side (waning) or more of the light side (waxing) the more of the dark side we see, the less moon there seems to be. The more light side, the more moon.
