I think if I was a researcher I would review my work or the sources I use, True
The smallest marble has the most kinetic energy therefore it would be the correct answer
The average speed is the ratio between the total space and the total time of the motion:
The total space is
while the total time is
So, the average velocity is
We can also rewrite it in m/s. The total space is
, while the time is
, and so
6 V drop occurs across the 6 ohm resistor in the parallel circuit diagram. The correct answer is C.
Since this parallel combination is connected with a cell, the potential difference through each resistor will be 6 volts. Now using I=V/R,
Current through 3 ohm resistor = 6/3 = 2 V
Current through 6 ohm resistor = 6/6 = 1 V
And the total current will be the sum of individual current in each resistor using Kirchoff’s junction law, Total current = 3 ampere
Since it is parallel combination the current passing across two resistors can differ but the voltage drop will remain the same.

Answer:
The expansion and contraction of materials can also cause problems. For example, bridges expand in the summer heat and need special joints to stop them bending out of shape.A bimetallic strip has two metal strips glued together. One of these metals expands more for each degree temperature rise than that other.
