concave <span>ray diagrams were constructed in order to determine the general location, size, orientation, and type of image formed by concave mirrors. Perhaps you noticed that there is a definite relationship between the image characteristics and the location where an object placed in front of a concave mirror. but, convex</span><span>ray diagrams were constructed in order to determine the location, size, orientation, and type of image formed by concave mirrors. The ray diagram constructed earlier for a convex mirror revealed that the image of the object was virtual, upright, reduced in size and located behind the mirror. </span>
This would be false. hope this helps. good luck :)
Answer:
It would take 
time for the capacitor to discharge from 
to 
.
It would take 
time for the capacitor to discharge from to 
.
Note that 
, and that
.
Explanation:
In an RC circuit, a capacitor is connected directly to a resistor. Let the time constant of this circuit is 
, and the initial charge of the capacitor be . Then at time 
, the charge stored in the capacitor would be:
.
<h3>a)</h3>
.
Apply the equation :
.
The goal is to solve for in terms of . Rearrange the equation:
.
Take the natural logarithm of both sides:
.
.
.
<h3>b)</h3>

Apply the equation :
.
The goal is to solve for in terms of . Rearrange the equation:
.
Take the natural logarithm of both sides:

Answer:
Action - Pulling up the train.
Reaction - Friction on the locomotive
Explanation:
Locomotive is pulling the train upwards ,
Which is the action force applied by the locomotive,
As a reaction locomotive will be pulled by the train which is the reaction of pulling
Now, considering it as a action on locomotive , friction force will act on it as a reaction upwards which will result to move it upwards.
For train action is pulling up by locomotive and reaction will be friction acting on it downwards.
