Answer:
Height of the balloon is 6.923 miles or 11141.46m
Explanation:
We form two triangles with a common vertex so the relation of the angles is and the position both are measuring
The second triangle have the mileposts on the road that is a mile more so:
Now resolve the both equation to know the opposite side that is the height of the hot air balloon
Height=6.923miles
Leigth can be find also
The measure can be express in meters so
Using Ampere's Law, the magnetic field produced inside this solenoid is given by
B = uo N I / h
where uo is the vacuum permeability, N is the number of turns in the solenoid and h is the length of the solenoid. Earth's magnetic field is around 50 microteslas in North America thus the current needed in the solenoid is
I = B h / (uo N) = (50 E-6 ) (4) / ((4 pi E-7)(6000) ) = 0.026 A
I = 26 mA
So you need a current of around 26 mA.
Light acts like a wave and particle.
If there is an experiment designed to detect waves, you will see light as waves.
Similarly, if you set up an experiment to detect particles, you will see light as particles.
Basically, how you see light depends on the circumstances.
Definitely THAT answer.
(This is sarcasm, as you gave no multiple choice answers.)
