The best example of an elastic collision from above is that of a cart which rammed into another one and they are now pushed apart. The last option is the correct answer. An elastic collision occurs when two objects bounce apart when they collide thus, preserving kinetic energy and momentum.
Answer:
the 5 is because u have to select the currents and volts which gives us 2 and 1 plus 3 is 6 but if we rest 1 is 5, thats the answer
Answer:
From the base unit of length, we can define volume, and from the base units of length, mass, and time, we can define energy. Volume. Since volume is length cubed, its SI derived unit is m3
Answer:
Solid sphere will reach first
Explanation:
When an object is released from the top of inclined plane
Then in that case we can use energy conservation to find the final speed at the bottom of the inclined plane
initial gravitational potential energy = final total kinetic energy
now we have
here k = radius of gyration of object
also for pure rolling we have
so now we will have
so we will say that more the value of radius of gyration then less velocity of the object at the bottom
So it has less acceleration while moving on inclined plane for object which has more value of k
So it will take more time for the object to reach the bottom which will have more radius of gyration
Now we know that for hoop
k = R
For spherical shell
For solid sphere
So maximum value of radius of gyration is for hoop and minimum value is for solid sphere
so solid sphere will reach the bottom at first
