Answer:
b) the potential difference across each is the same.
Explanation:
When resistors are connected in parallel with each other
then the terminals of all the resistors will connected across the terminals of the battery
So we know the potential difference of the battery is same across all the resistors
So we can say that the equivalent resistance of all the resistance is
so its not the mean of all resistors
also we know that the resistance are all different so power across each resistance is different given as
also current in each resistance is also different and given by
so correct answer will be
b) the potential difference across each is the same.
After the great 1906 San Francisco earthquake, geolophysicistHarry Fielding Reid examined the displacement of the ground surface along the San Andreas Fault. He concluded that the quake must have been the result of the elastic reboundof the strain energy in the rocks on either side of the fault.
strain energy is 0. 5x force x (compression) X (compression)
There is a lot of force and a bit of compression when rocks squash up against other rocks causing earthquakes
C. has to be right, also its the only one that makes sense.
Hope this helps!
We want to study the impact of a sledgehammer and a wall.
Before the sledgehammer hits the wall, it has a given velocity and a given mass, so it has momentum and it has kinetic energy.
When it hits the wall, the velocity of the hammer disappears, this means that the energy is transferred to the wall, this "transfer of energy" can be thought of a force applied for a really short time on the wall, which for the third law of Newton, the force is also applied on the hammer.
This is why you feel the impact on the handle when you hit something with a hammer, this also means that some of the energy is dissipated on your arms.
Now, because the wall is made of a material usually not as strong as the head of the sledgehammer, we will see that in this interaction the wall seems more affected than the hammer, but the forces that each one experiences are exactly equal in magnitude.
