Answer:
- So, the force its
N to the west.
Explanation:
The force 
on a charge q made by an electric field 
its
The electric charge of the electron its
.
Taking the unit vector 
pointing towards the east, the electric field will be:
.
So, the force will be:
So, the force its N to the west.
Average velocity is given by the ratio of total displacement /total time taken in order to do that
thus it will be
30.5-50.0/3 = 6.5 m/s
Answer:
t = 20 s
Explanation:
145 m = 9 m/s × t – 35m
We can obtain the value of t in seconds by doing the following:
145 m = 9 m/s × t – 35m
Add 35 m to both side as shown below:
145 m + 35 m = 9 m/s × t – 35m + 35 m
180 m = 9 m/s × t
Divide both side by 9 m/s
t = 180 m / 9 m/s
t = 20 s
Therefore, the value of t is 20 seconds.
The best question that could prompt a scientific investigation is: <u>What substances dissolve in ocean water?</u>
This way the person experimenting can use several variables and make observations. Upon making observations, the person can be able to gather as much data as he can in order to answer the original question that he asked.
