Answer:
the Earth magnetic field in that region is about 89.09 
T
Explanation:
If the magnetic field has an inclination of 
, and its horizontal component is 17 microTesla, then we can calculate the magnitude of the full magnetic field via the cosine function. Notice that the decomposition of a vector in horizontal and perpendicular components originates a right angle triangle where the vector is the hypotenuse of the triangle.
The amount of sunlight received per square centimeter is different by 36 times less.
<h3>What is the speed of light?</h3>
A fundamental physical constant, typically abbreviated as c, the speed of light in a vacuum is significant in many branches of physics. 299792458 metres per second, or around 300000 kilometres per hour or 186,000 miles per hour, is the precise figure. The special theory of relativity states that the maximum speed at which ordinary matter, energy, or any signal containing information may move across space is given by the constant c.
Visible light is an example of electromagnetic radiation that moves at the speed of light. Light and other electromagnetic waves appear to move instantly for many practical uses, but their limited speed has dramatic implications over vast distances and particularly sensitive measurements. The starlight that can be seen from Earth has been out there for a very long time, allowing people to see far-off objects and learn about the evolution of the cosmos. It can take minutes to hours for signals to reach from Earth to a spacecraft when corresponding with far-off space missions. The absolute shortest communication latency between computers, to computer memory, and within a CPU is fixed in computing at the speed of light.

Answer:
a) Not Accurate
b) Not Accurate
c) Accurate
d) Accurate
Explanation:
Part a
Not Accurate, because destructive interference would lead to maximum possible magnitude of < 3 m
Part b
Not Accurate, because constructive interference would lead to minimum possible magnitude of > 2 m
Part c
Accurate, because destructive interference would lead to maximum possible magnitude of < 3 m by varying the phase difference between two waves she can achieve the desired results.
Part d
Accurate, because constructive interference would lead to minimum possible magnitude of > 2 m by varying the phase difference between two waves she can achieve the desired results.
