Answer:
a. True
Explanation:
Distance is described with only magnitude. It is defined as the total path covered by an object, in other words it is the length of a path followed by a particle.
Displacement is described with both magnitude and direction. It is distance traveled in a specified direction or change in position in some time interval.
Therefore, the correct option is " a. True"
Answer:
- a.
- b.
Explanation:
<h3>
a.</h3>
The equation for the voltage V of discharging capacitor in an RC circuit at time t is:
where 
is the initial voltage, and 
is the time constant.
For our problem, we know
and
So
This gives us
and this is the time constant.
<h3>
b.</h3>
At t = 18.8 s we got:
