TORQUE
When does torque increase?
A greater force is applied, or when the distance from the pivot point increases.
Why does fluid pressure increase as depth increases?
Because the weight of all the fluid increases as depth increases. (Object go down, fluid build on top, fluid is real thing-- has weight. Because weight, fluid become very heavy.)
A garden hose sprays water. If you partially cover the nozzle with your thumb, what happens to the speed and pressure of the water coming out?
(HINT: up & down)
Speed increases and pressure decreases.
How do you describe a wave?
A disturbance that transfers energy through a medium or vacuum.

If Ben wants to get a bolt out of his car, what wrench should he use to generate more torque? The longer one or the shorter one? Why?
The longer one! (Explanation ni classmate that will be approved by sir barrete)
The hole closest to the bottom of the bottle; because pressure increases with depth.
In a pipe, what has higher pressure? A wider section or a narrower section? Why?
A wider section because SPEED down PRESSURE up! In a wider section, the fluid would have to take more time to travel than in a narrow section, so it has higher pressure! (I will also ask Maser or Matteo or Aaron to explain)
What is an example of a mechanical wave that requires a medium to travel?
(Verify with sir barrete if its correct)

"Torque is always the same regardless of the angle between the applied force and the lever arm." Is this statement true or false? Why?
False because torque depends on the angle between the applied force and the lever arm. Basically, the angle that you apply force to perpendicular to the pivot point matters.
Lets say Gab Ryan, Dylan Kyle Torio, Tyshaun Esteban and Maser Cabacungan wanted to climb a mountain. They started from the foot of the mountain at sea level to the very top. What happened to atmospheric pressure as they rise? Why does this happen?
How are Airplanes generating lift an example of Bernoulli's Principle?
What are the three main types of waves?
Mechanical, Matter, and Electromagnetic
In the hit TV Series, Avatar the Last Airbender, a young boy named "Aang" is suddenly made the Avatar, and thus the savior of the world. This is a large burden for a 12 year old boy like Aang, and so he finds himself bringing along a small furry companion on his journey. What is the name of this companion? What kind of animal is it?

A student uses a wrench to loosen a bolt. The student applies a 40 N force at the end of the wrench 0.5 m from the pivot. The force is applied perpendicular to the wrench. What is the torque produced? (Answer in Newton Meters)
20 Nm
A hydraulic press uses a small piston and a larger piston connected by a fluid. What principle allows a small force applied to the small piston lift a heavy object on the larger piston? Explain why.
Pascal's Principle as When you push on a fluid in a closed container, the pressure spreads equally everywhere in the liquid.
What does Bernoulli's Principle state?
In a flowing fluid, when the fluid moves faster, its pressure becomes lower, and when it moves slower, its pressure is higher.
Describe a longitudinal wave.
(Confirm with Sir Barrete)
From google:
A longitudinal wave is a mechanical wave in which particles of the medium vibrate parallel to the direction of wave propagation, creating alternating regions of compression and rarefaction

Gravi-tea HAHAHAHAHAHA
A 50 N force is applied to a lever 2 m from the pivot at an angle of 30° relative to the lever. What is the torque? (Answer in Newton meters)
50 Nm
A hydraulic press has a small piston with an area of 0.01 m² and a large piston with an area of 0.5 m².
If a 100 N force is applied to the small piston, what force will act on the large piston?
5,000 N
A horizontal pipe narrows from a cross-section of 0.05 m² to 0.025 m². Water velocity in the wide section = 2 m/s, pressure = 120,000 Pa. Find the pressure in the narrow section.
114,000 Pa
When does diffraction occur?
When a wave spreads out after going through a narrow opening.
