I will assume that you want to know if the driver can stop before hitting the obstacle or not.
First step is to use the reaction time in order to know how far can she go before her motion starts to slow:
distance = velocity x time = 20 x 0.5 = 10 m
Thus, the driver has 50 - 10 = 40 m to stop before colliding
Second step is to calculate the distance that the driver requires to stop using the rules of velocity and distance:
1- velocity = acceleration x time
20 = 6t ..............> thus, time = 3.334 seconds
2- distance = 0.5 x a x t^2 = 0.5 x 6 x (3.334)^2 = 33.3466 m
From the previous calculations, we can see that the driver has 40 m to stop and she needs only 33.3466 m to stop based on the given parameters. This means that she can stop before collision.
Answer:
A
The current through the solution is
B
The current is moving from B to A
Explanation:
From the question we are told that
The number of that move from A to B is
The time taken to move from A to B
Since the value of 1 charge is
The quantity of charge Q that flow from A to B is mathematically given as
The number of that move from A to B is
Since time taken to move from A to B is equal to time taken to move from B to A
The quantity of charge Q that flow from B to A is mathematically given as
The total quantity of charge is
The current flowing through the solution is
The flow is from B to A cause current flow from the positive terminal to negative terminal
The answer is A because when you relocate something you’re moving it to a different place from where you had it at first
