Given :
A spring with a spring constant of 1730 N/m is compressed 0.136 m from its equilibrium position with an object having a mass of 1.72 kg.
To Find :
The embankment in the height.
Solution :
Since no external force is acting in the system, therefore total energy will be conserved.
Initial kinetic energy of the object = Energy stored in spring
Also, initial potential energy is 0.
Now,
Therefore, the embankment height is 0.64 m.
Answer:
Explanation:
As resistor is connected to the battery of constant EMF then the power across the resistor is given as
now if two resistors are made up of same material and of same length then due to different cross sectional area they both have different resistance
Due to different resistance they both will have different power
Since power is inversely depends on the resistance
So if the power is twice that of the other then the resistance must be half
so we have
since one resistance is half that of other resistance
So the area of one must be twice that of other
so we have
