Answer:
It is example of Closed system
(30, 5)
(10, 1)
change of y / change of x
= (30 - 10) / (5 - 1)
= 20 /4
= 5
Answer:
The magnetic field is 14.08 T.
Explanation:
Given that,
Speed of electron 
Distance 
Suppose we need to find the magnetic field at the location of the proton
We need to calculate the magnetic field
Using formula of magnetic field
....(I)
Using formula of current

Using formula of time

Put the value of current and time in equation (I)

Put the value into the formula


Hence, The magnetic field is 14.08 T.

-244.59meters
Explanation:
The initial position of the object is located at -244.59meters from the origin.
Displacement is the distance from the start to finish of a body.
Final position of the body is at x=-55.25 meters
Amount of displacement is -189.34meters;
let us represent this by a coordinate system in the negative x - direction;
Origin
Start finish 0m
-a -x
-55.25meters
displacement
-189.34meters
Position -a is about 189.34 in left direction from 55.25; this gives: 55.25 + 189.34 = -244.59m in the left direction
