Answer:
Electrons.
Explanation:
Electricity was discovered before the discovery of electrons by J.J Thompson in 1896. Before the electron, it was thought that it is the positive ions that move through the wire and carry current—that's why today the conventional current represents the flow of positive charges.
After J.J Thompson's discovery of the electrons, it was realized that it is the electrons that actually carry the current through the conductor. But changing the direction of the conventional current didn't seem appropriate, and that's why the convention continues to be used to this day—reminding us that once it were the positive ions that were thought to carry the current.
Explanation:
Distance covered = Total distance travelled by the car
Since the car travels to school and back to home again,
Total diatance covered = 8 + 8 = 16km
Displacement = Shortest distance between start point and destination.
Since, the car returns back to home from school,
the start and destination point are same.
So Displacement = 0
Pelvic girdle
In human anatomy, the pelvis is a complex of bones that connects the trunk and the legs, supports and balances the trunk, and houses and supports the intestines, the urinary bladder, and the internal organ. It is sometimes referred to as the bony pelvis or the pelvic girdle.
One is located on the left side of the body and the other is located on the right. They come together to make the pelvic girdle, a portion of the pelvis. The hip bones are attached to the upper portion of the skeleton at the sacrum.
The pelvic girdle's main function is to support the upper body's weight while seated and transfer that weight to the lower limbs while standing. For the muscles in the trunk and lower limbs, it functions as attachment point.

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 "
".
Now,
Now total moment of inertia = sum of inertial moment due to all of the dumbbell
⇒ 
⇒ 
<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".

And now we can infer from this one,
⇒ 
So that "I1 > I2" is the right answer.
