Answer:
3.03°
Explanation:
Given that
Height of the tree branch, h = 4.5 m
Distance of the veterinarian away, d = 85.5 m
The vet is to aim at the monkey at a particular angle. If we consider the force of gravity that will be acting on the dart. Then the angle that will be needed will be calculated as this.
So the angle is
Tan θ = opposite / adjacent
Tan θ = 4.5 m/ 85.5 m
Tan θ = 0.053, then
θ = Tan^-1 (0.053)
θ = 3.03°
Therefore, the angle needed is 3.03°

Answer:
Meandering
Explanation:
A meander is known as the continuous flow of regular curves which are sinuous, loops, turns, bends or winding in the channel of river
Production of a meander by a river or stream as it erodes the sediments comprising on an exterior, a concave bank and deposits it and other sediment on the downstream on an interior, convex bank which is like a point bar.
Rivers or streams with a one channel and sinuosities of 1.6 or more are defined as meandering rivers or streams.
Explanation:
It is given that,
Wavelength 1,
Wavelength 2,
Energy of a photon having wavelength 1 is given by :
Energy of a photon having wavelength 2 is given by :
Hence, this is the required solution.
