Answer:
C1/C2 = 0.213 or C2/C1 = 4.68
Explanation:
Please refer to the attached image for step by step explanation.
Answer:
A. 65 degrees
Explanation:
The formula to calculate the range of a projectile is:
where
u is the initial speed of the projectile
g is the acceleration of gravity
is the angle of projection of the projectile
We want to find the angle such that it has the same range of a projectile fired at , therefore:
It follows that
And there are two angles that satisfies this condition:
and
In fact, with the second choice,
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.
Wrap the wire around the nail. the more wire you wrap around the nail the stronger your electromagnetic will be. make sure you leave enough wire so you can attach the battery. also when you wrap the wires around the nail make sure that you wrap the wires all in one direction ( i learned this in elementary)
That's kind of an intuitive description of an "open circuit".
