1.) Ohm's law is understood as I = V/R. Given that resistance is constant, then voltage changes directly proportional to current.
2.) The more current that passes through a lightbulb, the brighter it glows. The higher the current, the higher the power, where power determines the brightness of a bulb.
3.) A bulb has a specific limit to how much power (Watts) it can handle. Going over the limit would cause the bulb to burn out.
4.) When a bulb burns out, no current will be able to pass through the filament.
A. Gravity pulls you when air resistance to parachute makes it slow
Answer:
The answer from this question is 3 m/s2.
Explanation:
8 m/s is initial velocity and 32 is final velocity. According to the rule of acceleration vf - vi we minus 8 from 32. Acceleration is the change of velocity per unit time. Then the difference (32 - 8= 24) is divided to 8. We get 3.
<span>In Egypt, the physiologic density is 2580 persons per square kilometer greater than the arithmetic density which is 75, because most of the country's land is not suitable for agriculture.
The land which is suitable for agriculture is called arable land. when physiological density is larger than arithmetic density it means country less arable land.</span>
Answer:
What is kinetic friction?
Kinetic friction is defined as a force that acts between moving surfaces. A body moving on the surface experiences a force in the opposite direction of its movement.
What causes it?
When the mass is not moving, the object experiences static friction. The friction increases as the applied force increases until the block moves. After the block moves, it experiences kinetic friction, which is less than the maximum static friction.
What does it generate?
When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to heat). This property can have dramatic consequences, as illustrated by the use of friction created by rubbing pieces of wood together to start a fire.
