Your eyes and brain would first register the event nearby sooner than the one farther away
The answer is A because potential energy is stored up energy which means that it’s not moving
Answer:
Explanation:
We know that for a capacitor 
, where <em>Q </em>is the charge of one plate, <em>C</em> the capacitance and <em>V</em> the potential between the plates.
We also know that 
, since 
is the surface charge density and <em>A</em> the area of the plate (both equal in our case).
Putting all together:
Which for our values is:
Where we notice that the S.I. units combination FV/C must not have units (we can verify it directly from their definitions or we notice that 
is enough to describe an area).
Answer:
A. 1.8x10⁵
Explanation:
For this question we have
72km/h = speed
Total mass = 2250kg
Stopped at t = 0.2250s
To get average force acting on this car on collision:
72km/3.6 = 20m|s
Impulse = ∆p
This implies:
F∆t = m∆v
F = m∆v/∆t
= 2250x20/0.250
= 180000
= 1.8x10⁵
Therefore option A is correct.
Answer:
3300 J
Explanation:
P = Q/t
Q = Pt = 110 * 30 = 3300 J
