McDonnell Douglas F/A-18 Hornet Top speed is 1,190 mph (Mach 1.8).

A ball bounces because it's shape changes when it hits another object, then it returns to it's original form, pushing itself away from the object. When a ball is cold it's molecules don't move as much, so the shape changes less when it hits an object.

Breakaway torque is the amount of torque required to overcome the static friction of a stationary object and set it in motion. It is a measure of the minimum force or torque needed to break something free from its initial position.

Simply because physicists discovered that it is a product that is conserved.

In collisions of two objects for example, if you add up the momentum before the collision the momentum will be the same after the collision.

Note that momentum is not something that has a concrete reality.

A rock sitting on the ground has zero momentum relative to us here on earth but has alot of momentum relative to someone on mars. It can not have zero momentum and alot of momentum at the same time, it depends on ones frame of reference. My point is that momentum is not at 'concrete" thing.

Refer to the 'Conservation of linear momentum' in Wikipedia.org, "The World's Encyclopedia"

No, changes in the rock cycle do not create or destroy matter; they simply redistribute and transform existing matter. Rocks are broken down into sediment, which is then compacted and cemented to form new rocks through processes like erosion, deposition, and lithification.

Im not sure either but i kno my dad took something off of mine and made it go atleast 40.

Inertia exist because of the Law of Motion of Sir Isaac Newton states that " bodies at rest will remain at rest and objects in motion will continue moving at constant speed in a straight line unless acted upon a net force.

The B-2 Spirit's top speed is 1333 mile per hour. That is approximately Mach 1.7 or Mach 1.8.

Sound is the perception of changes in pressure in the air.
Slow changes of pressure cannot be heard. Once the changes happen faster than 20 times a second, you start to hear sound. Above 16,000 changes per second and it goes beyond human perception.
You need air (or any gas) for sound to exist. Sound cannot be heard in a vacuum.

Sound waves from a radio typically travel through the air as it is a medium that allows for the propagation of sound waves. Sound waves are generated by the radio transmitter and then travel through the air as vibrations in the form of pressure waves to reach the receiver.

It appears that the terms you provided, "Time65," "miles per hour," "time65," "t65," all represent the concept of time measured in minutes or hours. The term "65 miles per hour" specifically represents speed, indicating a rate of 65 miles covered in one hour.

The work done on the gas during compression is given by the formula W = PΔV, where P is the average pressure and ΔV is the change in volume. So, the work done on the gas during compression is (1123000 + 2445000)/2 * (20.81 - 11.25) = 10600475 J. Since no heat is transferred to the environment and the process is adiabatic, the change in internal energy of the gas is equal to the work done on the gas, so ΔU = 10600475 J.

Dimensional homogeneity refers to the concept that the units on the left-hand side of an equation must be equivalent to the units on the right-hand side for the equation to be mathematically valid. It is widely used in physics and engineering to ensure that equations accurately represent physical relationships and can be used consistently in calculations without errors due to mismatched units.

The two divisions of mechanics are classical mechanics and quantum mechanics. Classical mechanics deals with macroscopic objects moving at speeds much slower than the speed of light, while quantum mechanics deals with the behavior of very small particles at the atomic and subatomic level.

In a gas, molecules are relatively far apart and have the energy to move quickly.

The maximum principal stress theory is generally applicable to materials that exhibit ductile behavior, such as many metals and alloys, where failure occurs when the maximum principal stress in a material exceeds its ultimate tensile strength. This theory is not suitable for brittle materials, as their failure is often governed by factors other than stress alone.

gunpowder burns creating great heat , air pressure increases proportionally , and, like an air rifle, immense pressure creates force on back of slug accelerating it along the tightly fitting gun barrel. Imagine say 20g slug accelerated (assume uniformly) to 2000m/s in 10cm of gun barrel and calculate average force required to do it , this being testimony to gunpowder's tremendous potential energy.

The U.S. government lowered the speed limit to 55 miles per hour during the 1970s energy crisis in an effort to conserve fuel. This nationwide speed limit was part of a broader strategy to reduce oil consumption and dependency on foreign oil.

He is incorrect. Newton's 3rd law states that any force has an equal and opposite force. This means he pushes back on the water with the oars (normal), and this creates a forward normal force on the oars pushing the oars and the boat forward.

Maxwells equations are a set of 4 equations that explain the fundamentals of Electricity and Magnetism.

They read like this.

1. The Closed integral of Electric Field with Respect to Area is equal to Enclosed Charge over epsilon not.

2. The Closed integral of Magnetic field is equal to zero.

3. The Closed integral of Electric Field with repsect to distance is equal to the negative derivitive of magnetic flux with respect to time.

4. The Closed integral of Magnetic Field with respect to distance is equal to the quantity of mu not times enclosed current plus the quantity of epsilon not mu not times the derivitive of Electric Flux with respect to time.

In order to really understand the applications of these equations, I would suggest taking an entire calculus based physics course on Electricity and Magnetism, as well as a Calculus Course.

The primary process that moves water from the liquid state back into the atmosphere as water vapor is evaporation. Evaporation occurs when water molecules gain enough energy to break free from the liquid surface and become vapor in the air.
