Your dog ran 400 kilometers due north. Your dog then turned around and ran 300 kilometers due south. What was your dog's displac

400 km - 300 km = 100 km, since the dog stopped only 100 km away from where he had originally started out.

A dumbbell-shaped object is composed by two equal masses, m, connected by a rod of negligible mass and length r. If I1 is the mo

Sati [7]

Answer:

The correct answer to the following question will be Option A (I1 > I2).

Explanation:

Method for moment of inertia because of it's viewpoint including object at a mean distance "r" from the axis is,

⇒ mr²

<u>For Case 1:</u>

Let the length of a rod be "r".

The axis passes via the middle of that same rod so that the range from either the axis within each dumbbell becomes " $\frac{r}{2}$ ".

Now,

Now total moment of inertia = sum of inertial moment due to all of the dumbbell

⇒ $l1=m(\frac{r}{2})^2+m(\frac{r}{2})^2$

⇒ $\frac{mr^2}{2}$

<u>For Case 2:</u>

Axis moves via one dumbbell because its range from either the axis becomes zero (0) and its impact is zero only at inertia as well as other dumbbell seems to be at a range "r" from either the axis

Now,

Total moment of inertia = moment of inertia of dumbbell at distance "r".

$l2=mr^2$

And now we can infer from this one,

⇒ $mr^2>\frac{mr^2}{2}$

So that "I1 > I2" is the right answer.

Answer:

B) It is connected in parallel and measures potential differences.

Explanation:

A voltmeter measures electrical potential differences between two points in an electric circuit. It is also connected in parallel to measure a device's voltage, while an ammeter is connected in series to measure a device's current.

Hope this helps! :)
