Answer:
Explanation:
When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.
The problem describes the relationship of "bulb a" and "bulb b" to be in connected in series. When the switch is open then no current can flow, on the other hand, when it is closed, current will pass through.
When only "bulb a" is connected to the battery then more current is flowing to "bulb a" causing it to be bright.
Closing the switch would mean that "bulb b" is already included in the circuit and the battery will push small current to flow around the whole circuit. The more bulbs are connected, the harder for the current to flow because the resistance will be very high.
So the light of "bulb a" will be dimmer.
Answer:
one gram of water to one-degree Celsius.
Explanation:
Answer:
The force between them is, F = 8.33 x 10⁻¹¹ N
Explanation:
Given data,
The distance between the proton and electron, x = 12 nm
= 12 x 10⁻⁹ m
The electrostatic force between them is given by the formula,
Where k = 9 x 10⁹ Nm²C⁻²
Substituting the given values,
F = 8.33 x 10⁻¹¹ N
Hence, the force between them is, F = 8.33 x 10⁻¹¹ N
