Series circuits - cpt connected so that the same current passes through each of them.
Disconnection/break in series circuit and current doesn't flow.
Current same
The total potential difference across all of the components. (the sum of the pds across the individual series elements).
The diagram in the enclosure seems to show resistors in parallel. Which is a bit confusing ...
At First, there is chemical Energy( in your muscels) which is Used to Push down the spring. This Energy becomes the Energy of the spring, which increases until you stop pushing. If you Put your hand away, the Energy of the spring will become kinetic energ. This Energy is at the highest Level the Moment the book ist Leaving the spring. Afterwards, the kinetic Energy decreases while the Gravitational Potential Energy increases.
The speed of both cars is the same ... 80 km per hour.
But their velocities are different, because DIRECTION is part of velocity, and their directions are different.
Answer:
-352.275KJ
Explanation:
We are given that
Mass of car=1500kg
Initial speed of car =u=96 km/h=
1km/h=
Final speed of car=v=56km/h=
Distance traveled by car=s=55m
We have to find the work done by the car's braking system.
Using third equation of motion
Where negative sign indicates that velocity of car decreases.
Work done by a car's barking system=
Work done by a car's barking system=
Work done by a car's barking system=
1KJ=1000J
Where negative sign indicates that work done in opposite direction of motion.
