The "Standard Atmosphere" is 760 mm Hg .
2.13 times that pressure is (2.13 x 760) = 1,618.8 mm Hg.
Answer:
<h3>The 28 loops wound on the square armature</h3>
Explanation:
Peak output voltage 
V
Area of square armature 
Magnetic field 
T
Angular frequency 
According to the law of electromagnetic induction,
Where 
number of loops of wire.
≅ 28
Thus, 28 loops of wire should be wound on the square armature.
Output can not be greater than input because the conversion of energy can not be greater than 100%.
Answer:
Answer is 183.6 J
Explanation:
Using the Physics reference sheet the formula for Potential energy is
(mass) x (gravity) x (height)
Mass= 1.2
Gravity I used is 9.81 (use 10 to get the answer most schools use)
Height= 15.6
Answer:
If we use the equation for the transformation of velocities for moving frames:
v' = (v - u) / (1 - u * v / c^2) where we measure the speed of v' approaching from the left where v is in a frame moving at -u towards v'
v' = (.6 c - (-.6 c)) / (1 - (-.6 c) * .6 c / c^2) = 1.2 c / (1 + .6 * .6)
or v' = 1.2 c / (1 + .36) = .88 c
v is approaching from the left at .6 c in the reference frame and the other frame approaches from the right at -.6 c with speed u (-.6 c) and we measure the speed of v as seen in the frame moving to the left
