Answer:
λ2 < λ1
Explanation:
- Young's experiment of interference of light when passed through a slit has determined a result. We will use an expression derived from the results that relates wavelength and and the spread of the interference pattern using:
sin (Q) = n*lambda / d
Where,
n is the order of fringe about the central order
lambda is the wavelength of light
d is the space between grating
Q is the angle between the two successive interference fringe
- So in our case using a light of wavelength lambda 2 the pattern got closer together or we could say that angle Q got smaller. According to the relationship given we can see as angle Q decreases when lambda decreases. So we can conclude that λ2 < λ1.
Answer: Open system
According to thermodynamics, if a system exchanges matter and energy with its environment it is an open system. For example, human beings and animals can be considered as open systems, since we take chemical energy in the form of food and perform work on our surrounding environment when moving and doing activities.

Answer:
I'm not really sure as far as cell phone towers, but 5G hasn't published any safety tests, so we don't know for sure whether or not this would be harmful/cancer causing. The lack of evidence in either direction may be why we can't say definitively that it is safe or not harmful. Hope this helps.
Explanation:
The total electrostatic force on charge A is 
Explanation:
The magnitude of the electrostatic force between two charges is given by Coulomb's law:
where:
is the Coulomb's constant
are the two charges
r is the separation between the two charges
Here we have three positively charged particles A,B and C, located at the following positions:
The magnitudes of the three charges are:
The force exerted by B on A is to the left (because the force between two positive charges is repulsive), and the force exerted by C on A is also to the left (also repulsive). Therefore, the net force on A is just the sum of the two forces exerted by charges B and C:
