Answer:
Acceleration is the variation of Velocity in time :
(1)
This can be written as:
(2)
Where:
is the final velocity
is the initial velocity
is the final time
is the initial time
<u>Finally:</u>
The negative sign means the car is desaccelerating
<span>A massive, gravitationally bound collection of stars and stellar remnants is called a</span> Galaxy
<span>The time period from one moon to the next is called a <span>Month
</span></span>
<span>The period is averagely around 30 days...but we call it a Month. That's the answer. The word Month and Moon are sort of related. Month is simply from one Moon to the next Moon.</span>
Explanation:
The charge (positive or negative) is always on the surface in the conductors. So, if the plates have substantial thickness, the charge is distributed throughout the surface. We know from the question that the bottom plate is charged positively, so an equal amount of negative charge must be distributed on the lower surface of the upper plate.
The direction of the E-field is always directed from positive to the negative charge. Since the plates have flat surfaces, the electric field lines are straight, except the edges. In most college level questions this effect is negligible, that is why in most questions the plates are considered very large.
