A person would be driving 4 blocks west from the starting point to make the shorter distance while maintaining same displacement.
<u>Explanation:</u>
The measurement of an object’s position change from its point is called displacement. It is usually calculated from starting to the end points and represented by ‘delta s’. In the given scenarios, the person drove in the way that he finals the driving by 4 blocks away from the west.
Means, the persons drive to 8 blocks north and then to 8 blocks south get cancelled. Hence, to make the shorter distance with maintaining same displacement he would be driving 4 blocks west from the starting point.
Answer:
475 N/C
Explanation:
As we know that, the electric field in parallel plate capacitor is same (constant) throughout. And is potential gradient.
So, Electric field is given by
Electric field = potential gradient
Here, the potential change is 3.8V and the distance from negative plate to positive plate is 1.6 cm. The potential from negative plate to the center is (1.6/2)cm i.e., 0.8 cm.
But we have to take distance in SI units So, distance=
So, Electric field is
So, electric field is 475 Volts per meter.
Note : Also we can say 475 Newtons per coulomb
Machines makes work easier by increasing the amount of force that is applied, and changing the direction in which the force is applied !! Hope it helped (p.s. I had this same question)
