The power of batteries in a circuit. The key functions of a battery and bulb in a circuit are explained. A battery is a source of energy which provides a push - a voltage - of energy to get the current flowing in a circuit. A bulb uses the electrical energy provided by the battery, but does not use current.

Answer:
p = mv
Explanation:
- The momentum of a body is defined as the product of its mass and velocity. Its physical symbol is 'p'.
- The formula for momentum is given by
p = mv
Where,
m - the mass of the body in kg
v - velocity of the body in m/s
- Therefore, the unit of momentum is expressed as the kg m/s
- The momentum of a body is always associated with its motion. It is a vector quantity and it is directed in the direction of the velocity vector.
- If a body is at rest, the momentum associated with the body is zero.
- The momentum plays a significant role in the kinematics of the body. As similar to the energy conservation law, the total momentum of the body is conserved.

Newton's Third Law- For every action there is an equal and opposite reaction... Does this answer your question? If not, I can explain further...

Start by arranging the materials by the sonic speed and then their physical state:
- Copper (solid)
- Glass (solid)
- Wood (solid)
- Sea Water (liquid)
- Acetone (liquid)
- Alcohol (liquid)
- Helium (gas)
- Carbon dioxide (gas)
What trend do you identify from these data? Here's what I've got:

The way microscopic particles are arranged in a substance helps distinguish between different physical states:
- Particles in a solid are held tightly in place with small separation in between; it's hard for particles in a solid to move past one another; solids therefore have shapes that persists over time.
- Particles in a gas are highly mobile- they keep moving AT ALL TIMES. There are large separations between individual particles and therefore gases tend to show no definite shape or volume.
- The arrangement of particles in a liquid is located somewhere in between that of solids and gases. The exact configuration is dependent on the nature of the liquid- for example, molecules in maple syrup are held way closer to each other than those in distilled water are.
Sound travels as a longitudinal wave. As a sound wave passes through a medium, individual particles become excited and gain energy; as they run into others they transfer their energy to the next particle; the sound wave thus propagate across the medium. With a lower average distance between individual particles this action can proceed at a greater rate in average solids than in average liquids, and in average liquids than in average gases. Hence the trend.
