When using a doorknob the effort force moves through a smaller distance then does the resistance force?
When using a doorknob, the effort force exerted by your hand moves through a smaller distance than the resistance force needed to open the door. This is due to the mechanical advantage provided by the doorknob, allowing you to apply a smaller force over a greater distance to overcome the resistance force generated by the door.

How does the wheel of the doorknob multiply it's force?
The wheel of a doorknob multiplies force through the principle of leverage. When you turn the wheel of a doorknob, the rotation creates a mechanical advantage that allows you to apply a smaller force over a longer distance to open the door. This leverage magnifies the force you apply, making it easier to turn the knob and open the door.
Can air resistance affect the distance that a toy car does?
Yes, air resistance can affect the distance a toy car travels. A toy car moving through the air experiences air resistance, which can slow it down and reduce its overall distance traveled. Increasing the car's speed may also increase the impact of air resistance.
Out of the two bulbs in the house one glows brighter than the other which one of the two has a larger resistance?
The bulb that glows brighter has a smaller resistance. This is because a larger current flows through the bulb with smaller resistance, resulting in it glowing brighter.
Does air resistance act at a distance?
Yes, air resistance acts on objects moving through the air at a distance. It is a force that opposes the motion of the object and is proportional to the object's speed and surface area facing the direction of motion.
Why a smaller diameter wire has more resistance of electric current?
Resistance is defined as a property of materials due to which a material opposes the flow of current through themselves. And Resistance is inversely proportional to area of cross section of conductor. As the cross section area of thin wire is less hence resistance is more. So, as wire diameter increases its resistance decreases and vice versa

Will current travel along the path with the highest resistance?
Current goes path of least resistance. But if u have two resistances in paralell only the majority will go through the smaller resistance some Porportional Amount will "flow" through the larger resistor. Depends on resistance sizes and voltage slap plied as to how much current
Do longer or shorter restriction fragments travel farther?
Shorter restriction fragments travel farther in gel electrophoresis because they can move through the gel more easily due to their smaller size. Longer fragments experience more resistance and tend to travel a shorter distance through the gel.
How does air resistance affect the distance a projectile can fly?
Air resistance creates drag on a projectile as it moves through the air, which reduces its speed and range. The greater the air resistance, the more it will slow down the projectile and limit its distance. This is why aerodynamic design is important for improving the range of projectiles like bullets or rockets.
How does the size of the wire affect the electrical resistance?
The size of the wire directly affects the electrical resistance. Thicker wires have lower resistance compared to thinner wires, as there is more space for electrons to flow through, reducing the resistance. Conversely, thinner wires have higher resistance due to smaller pathways for electron movement.
What kind of machine is a doorknob?
A doorknob is not considered a machine; it is a simple mechanical device designed to open and close doors. It is typically made of materials such as metal or plastic and operates through manual turning or twisting to latch or unlatch a door.
How do you check if a door is hot?
Check the doorknob. A wooden door may not feel hot, even if the other side is burning (wood insulates). However, the metal doorknob, which goes all the way through the door, DOES conduct heat very well. If the doorknob is hot, so is the other side of the door.
Why does the oscillation of a pendulum gradually slows down after a certain interval of time?
