AC (Alternating Current) generator is a device that produces an electromotive force.This generator produces alternating current. Alternating current is electric current that changes its direction many times a second, at regular intervals. This is the type of current with which customers are supplied in the energy distribution network.
The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium....
In order to find which rational number is between 0 and 1, let's convert them into their decimal form:
Looking at the numbers in their decimal form, we can see that the number between 0 and 1 is one-fourth, therefore the correct option is the second one.
i believe it would be the same because time doesn't matter when calculating total work done.
Work=FxD
F=force
D=distance
Answer:
1 ) Distribution of mass within the ball
2 ) Height of the ramp
Explanation:
Acceleration of a rolling body down an inclined plane is given by the following formula
a = g sinθ / ( 1 + k² / R² )
k is radius of gyration , R is radius of the spherical object ,
when acceleration is more , velocity will also be more .
for objects in which masses are lying in the periphery like in hollow sphere , the value of k²/R² will be high so denominator of the expression will be high so acceleration will be less , hence velocity on reaching the bottom will be less.
On mass of the ball , velocity will not depend .
If height is increased , ball will have acceleration for greater time so velocity will be high.
On radius it will not depend because , radius r and k increases proportionately.
