A certain device in a 100 V circuit has a current of 34 A flowing through it. What is the resistance of the device? Rearrange the equation Current = Voltage Resistance to express resistance in terms of current and voltage.

The resistance of the device is .

Explanation:

The expression for the voltage in terms of resistance and current is as follows:

V=IR

Here, I is the current, R is the resistance and V is the voltage.

It is given in the problem that a certain device in a 100 V circuit has a current of 34 A flowing through it.

Calculate the resistance by rearranging the above expression.

Put I= 34 A and V= 100 V.

Therefore, the resistance of the device is .

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
