Refraction as in a pencil going into water
Note: The answer choices are :
a) Increased
b) Decreased
c) stayed the same
Answer:
The correct option is Increased
The magnitude of the electric field potential difference between the wingtips increases.
Explanation:
The magnitude of the electric potential difference is the induced emf and is given by the equation:

where l = length
v = velocity
B = magnetic field
As the altitude of the airplane increases, the magnetic flux becomes stronger, the speed of the airplane becomes perpendicular to the magnetic field, i.e.
,
the induced emf = vlB, and thus increases.
The magnitude of the electric field potential difference between the wingtips increases
Answer:
D
Explanation:
When something that needs power that you are turning off you will not need power when its off.
Answer:
TE = sqrt(GM/GE)TM
Explanation:
To solve for this problem, you have to use the second kinematic equation and set the height equal to each other. Because the heights are equal, 1/2GETE^2 = 1/2GMTM^2. Rearrange the equation and you'll get the answer
