Answer:
= 403 nm
Explanation:
We have the condition for the maximum for a diffraction grating
d sinθ =mλ
Then the grating constant d = w/N
= (75 mm)/(50,000)
= 0.0015 mm
Then wavelength of light is λ = (dsinθ)/m
= (0.0015 mm)(sin 32.5)/2
=403*10-6 mm
= 403 nm
An airplane requires a much less force in order to get off the ground than a rocket does, since a rocket needs to exit Earth’s atmosphere.
Planes typically travel at much slower speeds that traditional rockets, as they are faced with varying restrictions that affect how quickly they fly.
Both forms of transportation, although very different in certain aspects, are similar in the fact that they both need to adhere to similar constraints. Although most airplanes aren’t faced with the challenge of exiting the atmosphere, they do need to focus on their fuel, their safety, etc. just as rockets do as well.
Answer:
Explanation:
Given:
Electric Flux = 
Side of sheet = 5cm
Area of the square sheet, A= 5×5 = 25cm²=25×10⁻⁴ m²
Now
the electric flux (Φ) is given as:
where, E = Electric field
or
substituting the values in the above equation, we get
Now the charge density (σ) on a sheet is given as:
where, 
= Permittivity of the free space = 8.85×10⁻¹²
substituting the values in the above equation, we get
Answer: Rockstrom meant that it's going to be a challenging decade and that people will need to work hard and also bend the curve by thinking around the curve.
Explanation:
Some years ago, Johan Rockström, who was the executive director of Stockholm Environment Institute, and a professor at Stockholm University, was the head of an international team that was assembled in defining planetary boundaries.
The that was gathered to speak regarding issues that pertained to the Earth ane how it can be protected from being infiltrated ad protecting it from failing. During the conversation, Rockstrom said that it's going to be a challenging decade and that people will need to work hard and also bend the curve by thinking around the curve.
Answer:
Explanation:
If one assume that each turn is like a strand of electromagnet, which can then be added up. Therefore, increase in the number of turns will yield to increase in the magnetic strength. Also if the current increases, then there will be increase in the magnetic field strength.
From Ohm's law
V = IR
I = V/R
That is a direct increase in voltage will lead to increase in current.
Increase the voltage of the battery and increases the number of turns of the coil. Will suit the situation
