This causes the fluid to increase its speed. Bernoulli's principle tells us that an increase in the speed of a fluid happens at the same time with a reduction in pressure or a reduction in the fluid's potential energy. This necessitates that the amount of kinetic energy, potential energy and internal energy stays persistent.
My guess would be because the gravity from the Earth's core is constantly pulling the ball towards the ground. It's like the moon. Why doesn't the moon just float away in space? Because Earth's gravitational pull keeps it rotating around it. Therefore, the ball will always be pulled towards the core which keeps it from from rolling forever due to friction. But i may be wrong, even though this a quite a good answer, hope it is right!
Answer:
Heat energy
Explanation:
Electrons are flowing through the circuit, they pass through a resistor, in this case a light bulb. The energy is then transformed into light and heat energy.
Answer:d-All of the above
Explanation:
A resistor is a device used in electrical circuits that offers resistance to current flow.In automotive circuit commonly used resistor are
- Fixed value
- Stepped
- Variable
Fixed value:A fixed value electrical resistance is one whose value is resistance value is fixed and does not change in circuit.
Stepped resistance:Stepped resistor also called as tapped resistors provide two or more set resistor values. In a circuit, the various resistances are attached to different terminals. When the switch is shifted, different resistance values are put in the circuit.
Variable resistance:The variable resistor gives more control over the current flow by increasing the resistance. When the resistance of the variable resistor increases, the amount of current allowed to flow in the circuit decreases.
