i got 10,022 but im not sure if that's the fastest, i looked up the average and it was 3458 and one eighth

Yes, flying a kite is a density application because it involves utilizing the density difference between the air inside the kite and the surrounding air to generate lift. By harnessing this density differential, the kite is able to fly in the air.

Yes, it is possible for an object to be traveling with a non-zero velocity even if it is experiencing a net zero external unbalanced force. This is because the object may have inertia, which allows it to maintain its current velocity unless acted upon by an external force.

Light slows as it enters material with a higher density whereas sound waves speed up in materials of higher density.

Light bends towards the "normal" as it passes from a less dense medium to a higher density medium ie air into glass.

Both sound and light can be reflected from surfaces.

The the forces are unbalanced, that means that the net force is non-zero.

why cannot it be both? by definition, amplititude is the extreme range of fluctuating quantity. swing range of a pendulum, current flow,bla,bla,bla. amplitude MODULATION is in reference to radio waves with regards to signal RANGE ie: AM Radio- amplitude modulation am bounces and the range of frequency is modulated within the extreme band withs of the wave.

Momentum (P) is the product of mass (m) and velocity (v).

P = m X v

It's easy to get confused by combining metric units (grams) with imperial units (miles per second). Converting all the units to one system first will simplify calculations.

The net force is 2N north. This is because when you subtract the 5N force south from the 7N force north, you get a resultant force of 2N north.

Hardness of uranium metal:

Mohs hardness: 6

Brinell hardness: 2 400MN/m2

Vickers hardness: 1 960 MN/m2

Uranium is very hard and also very dense (19,05 g/cm3). Depleted uranium is used for artillery shells (also for tanks armour) to give it Armour piercing capability.

"100 mph tape" is a nickname often used for duct tape because of its versatility, durability, and ability to hold up even at high speeds like 100 mph. It is known for its strong adhesive properties and wide range of uses in emergency situations, repairs, and construction work.

Sound waves are generated by vibrations in air or a medium and travel in all directions from the source, whereas earthquake waves are generated by the sudden release of energy in the Earth's crust and travel through the Earth. Sound waves are longitudinal waves that can travel through gases, liquids, and solids, while earthquake waves consist of P-waves (compressional waves) and S-waves (shear waves) that travel at different speeds and have different effects on the Earth's surface.

The net force acting on an object is the combination of all individual forces acting on it. It is the vector sum of all forces, taking into account their magnitudes and directions. The net force determines the acceleration of the object according to Newton's second law of motion.

Cover your face, now... a sneeze. Incidentally, when you sneeze, it is impossible for you to keep your eyes open by force of will. Your eyes will close.

the frequency of a sound wave is higher if its wavelength is shorter

0. An object in equilibrium has constant velocity, which makes its acceleration 0. Since net force=mass times acceleration, this would make the net force zero.

Note that there could be multiple forces acting on the object, but since it is in equilibrium they would have to be equal and opposite in direction, to cancel all of the forces out. This would make the net force zero.

Yes, an object at rest can have forces acting on it. The vertical forces acting on an object at rest would include gravity pulling it downward and the normal force from a surface pushing it upward to balance the force of gravity.

Inthe kicking force, kinetic energy is acting on the ball together with Gravitational Potential Energy. Whereas the part where aother force is acting on iit while the ball is not moving is alsoocontrolled by gravitaitional potential energy.

In order for a body to escape the gravitational pull of the Earth, it needs to be thrown up with an initial velocity equal to or greater than the escape velocity of around 11.2 km/s. This velocity allows the object to overcome the gravitational pull of the Earth and continue traveling away from it indefinitely.

The ideal refrigerant has good thermodynamic properties, is noncorrosive, and safe. The desired thermodynamic properties are a boiling point somewhat below the target temperature, a high heat of vaporization, a moderate density in liquid form, a relatively high density in gaseous form, and a high critical temperature. Since boiling point and gas density are affected by pressure, refrigerants may be made more suitable for a particular application by choice of operating pressure. Corrosion properties are a matter of materials compatibility with the components used for the compressor, piping, evaporator, and condenser. Safety considerations include toxicity and flammability.

Usain Bolt has the highest recorded footspeed at 27.44 miles per hour.

At 180 degrees the net force is at a minimum; the two are working against one another.

There is no such thing as 'an unbalanced force', any more than a trouser,

a scissor, a tweezer, or a clapping hand.

A group of two or more forces is balanced if the vector sum of all of them

is zero, or unbalanced if it's not.

When a group of two or more forces is unbalanced, then the object they

act on exhibits acceleration.

The British government was worried that passengers traveling faster than 20 miles per hour on a locomotive would suffocate. This concern was due to the belief that high speeds would create a lack of oxygen inside the train cars, putting passengers' lives at risk.

23 miles per hour is approximately the fastest a human has run.

Yes, predictability is a property of gases. Gas behavior can be described using equations of state that allow scientists to predict how gases will behave under different conditions of pressure, temperature, and volume. This predictability is essential for many applications in chemistry and physics.
