The base unit for time is the second (the other SI units are: metre for length, kilogram for mass, ampere for electric current, kelvin for temperature, candela for luminous intensity, and mole for the amount of substance). The second can be abbreviated as s or sec.
Answer:
Vapors
Explanation:
We take into account that all the energy from the lightning has been transformed into steam.
We calculate the amount of energy required by water to convert into steam.
From the lightning we received 
of energy, out of which 
has been used to convert the water into steam.
Energy left = 
We use this energy to convert steam into vapors.
With this temperature, we can easily interpret that the vapors will be dissociated in hydrogen and oxygen particles.
(a) The magnitude of the wind as it is measured on the boat will be the result of the two vectors. Since they are at 90°, the resultant can be determined by the Pythagorean theorem.
R = sqrt ((20 knots)² + (17 knots)²)
R = sqrt (400 + 289)
R = 26.24 knots
The direction of the wind will have to be angle between the boat and the resultant.
cos θ = (20 knots)/(26.24 knots)
θ = 40.36°
Hence, the direction is 40.36° east of north.
(b) As stated, the wind is blowing in the direction that is to the east. This means that it only has one direction. Parallel to the motion of the boat, the magnitude of the wind velocity will have to be zero.
