From the question we are told that
The first wavelength is
The first angular size is
The second wavelength is
Generally according to Rayleigh Criterion we have that
given every other thing remains constant we have that
Here k represented constant so

Answer:
Assuming the typical saw used to saw boards in home construction and renovation is a circular saw, the diameter of the blade can be estimated as 7-10 inches (17.8-25.4 cm). The linear speed in m/s of a point on the rim of the circular saw blade is then approximately: (π × 25.4 cm) × (2600 rev/min) / (60 s/min) = 28.0 m/s.
Answer:
Composition. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter.

Answer:
The pressure of the remaining gas in the tank is 6.4 atm.
Explanation:
Given that,
Temperature T = 13+273=286 K
Pressure = 10.0 atm
We need to calculate the pressure of the remaining gas
Using equation of ideal gas
For a gas
Where, P = pressure
V = volume
T = temperature
Put the value in the equation
....(I)
When the temperature of the gas is increased
Then,
....(II)
Divided equation (I) by equation (II)
Hence, The pressure of the remaining gas in the tank is 6.4 atm.
If you ADD those displacements,
(4 km south) + (5 km south) = 9 km south
and
(2 km north) + (5 km north) = 7 km north
Then (9 km south) + (7 km north) = 2 km south
