Answer:
v = 1.2 m/s
Explanation:
The wavelength of the waves is given as the horizontal distance between the crests:
λ = wavelength = 5.5 m
Now, the time period is given as the time taken by boat to move from the highest point again to the highest point. So it will be equal to twice the time taken by the boat to travel from highest to the lowest point:
T = Time Period = 2(2.3 s) = 4.6 s
Now, the speed of the wave is given as:

where,
v= speed of wave = ?
f = frequency of wave = 
Therefore,

<u>v = 1.2 m/s</u>
I guess the problem is asking for the induced emf in the coil.
Faraday-Neumann-Lenz states that the induced emf in a coil is given by:

where
N is the number of turns in the coil

is the variation of magnetic flux through the coil

is the time interval
The coil is initially perpendicular to the Earth's magnetic field, so the initial flux through it is given by the product between the magnetic field strength and the area of the coil:

At the end of the time interval, the coil is parallel to the field, so the final flux is zero:

Therefore, we can calculate now the induced emf by using the first formula:
2 atoms of P (phosphorus) and 5 atoms of O (oxygen)
Explanation:
The chemical formula of a generic compound is written as

where
A and B are the symbols of the elements contained in the compound
n and m are the number of atoms of each element, A and B respectively
In this problem, the compound given is

where:
- P is the symbol of the chemical element phosphorus
- O is the symbol of the chemical element oxygen
We see that the number following P is 2, so there are 2 atoms of phosphorus, while the number following O is 5, so there are 5 atoms of oxygen.
