Answer:
i think the answer would be:Jonas’ brother gets out of the cab of the truck and sits in the back of the truck with the furniture. With less mass, they should be able to push the truck to the gas station.
Explanation:
I think the answer is B because I did this before
Answer:

Explanation:
Since the field lines are parallel and the electric field is uniform between two parallel plates, a test charge would experience the same force of attraction or repulsion no matter where it is located in the field,
I attached an image that could help to understand the representation of the field. The formula used to calculate it is given by,
(1)
If we want to consider the change in Voltage with respect to the position then it would be,

According to the information provided, the potential is
and there is a distance d, therefore
(2)
Taking equation (1) we can clear V, to what we have,


Integrating,

Substituting (2)


Where x is the height from the grounded plate.
To solve this problem it is necessary to apply the concepts related to thermal linear expansion. Mathematically this concept can be expressed under the Equation:

Where,
Initial Length
Thermal Expanssion constant
Change in Lenght
Our values are given as



Replacing at our equation we have,



Therefore the expantion of the bar is 0.317mm
A. a steel beam. All of the rest of them change shape or volume whereas a steel beam with never change in volume or shape.
