Here are a few ideas for a Rube Goldberg machine that closes a fridge door:

A marble rolls down a ramp and hits a small lever.

The lever activates a toy car that rolls down a track and hits a domino.

The domino falls and triggers a chain reaction that results in a weight falling onto a lever.

The lever pulls a string that is attached to a door handle.

The door handle turns and the fridge door closes.

Answer:

A marble rolls down a ramp and hits a small lever.

Answer:

39,200J

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J

Answer: Describe how plates create mountain ranges like the Himalayas.

Answer- Most of the world's largest mountains form as plates collide at convergent plate boundaries. This creates mountains. Folding and faulting in these collision zones makes the crust thicker. The world's highest mountain range, the Himalayas, is growing as India collides with Eurasia

2. Diagram how pulling apart continental crust could create mountains and basins. What are the mountains and

basins called? Answer- When tensional stresses pull crust apart, it breaks into blocks that slide up and drop down along normal faults. The result is alternating mountains and valleys, known as a basin-and-range

Image result for what's newton's second law

Newton's second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation.

Answer:

when the molecules are heated , they move faster and the space between them will increase . they become very lossly packed and thus evaporate. this process can also be called evaporation in detail

when the molecules are cooled down, they move slower and they have very less space between. they becomes tight as they are cooled tgus condenses this process can also be called as condensation in detail

Answer:

When the molecules are molecules are heated the bond holding the molecules together becomes lose and hence making the molecules to vibrate and move more faster which also makes the kinetic energy to increase.

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity

Electromagnetic waves are created when an electric field collides with a magnetic field. Electromagnetic waves are the type of waves emitted from the light source.

EM waves are another name for electromagnetic waves. Electromagnetic radiations are made up of electromagnetic waves created when an electric field collides with a magnetic field.

Electromagnetic waves may alternatively be defined as the combination of oscillating electric and magnetic fields. Maxwell's equations are solutions to electromagnetic waves.

Electrically charged particles experiencing acceleration create electromagnetic waves, which can then interact with other charged particles and exert force on them.

In light source 2 the particle is electrically charged and accelerates the electromagnetic wave. Hence Electromagnetic waves are the type of waves emitted from the light source.

One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.

Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.

The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.

Friction:-

The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object. For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion. Friction results from the two surfaces being pressed together closely, causing inter molecular attractive forces between molecules of different surfaces. As such, friction depends upon the nature of the two surfaces and upon the degree to which they are pressed together. The maximum amount of friction force that a surface can exert upon an

EG:-

A coaster sliding against a table.

Gravity:-

The force of gravity is the force with which the earth, moon, or other massively large object attracts another object towards itself. By definition, this is the weight of the object. All objects upon earth experience a force of gravity that is directed "downward" towards the center of the earth. The force of gravity on earth is always equal to the weight of the object as found

EG:-

The force that causes a car to coast downhill even when you aren't stepping on the gas.

Elastic:-

Elasticity is the ability of a material to return to its original shape after being stretched or compressed. When an elastic material is stretched or compressed, it exerts elastic force. This force increases the more the material is stretched or compressed.
