Helium will make a basketball bounce higher because when it is put into the basketball the air particles move faster and faster causing the basketball to bounce higher.

About 25.5mph assuming my math is correct: 5280ft/330=16 16x9.68=2min35sec 60mph/2.6min=25.5mph

The above answer is incorrect. This would be true if it was a constant velocity, but because the runners are starting from a stop you need to factor in acceleration. But again we run into a problem because the acceleration is not constant so calculating the final velocity would be a bit tricky. A time of 9.68 the runner would probably be going close to 30mph.

NO, speed tastes better

Usain Bolt is the fastest human, ever, winning many Olympic gold medals. His fastest speed was a little bit over 27 mph. So your answer is 'no'.

Of course, we know nothing of fast humans before they started timing sprints and recording the times.

Yes. As the car goes down the hill, the potential energy decreases and the kinetic energy increases. However, not all of the potential energy becomes kinetic energy. Some of it is lost to heat and sound energy.

the largest moving object is a train

I believe the largest man made moving object is a oil tanker called the Jahre Viking which has a dead weight of 564,763 tons and is so big it can't navigate through the English Channel, it carries a cargo close to its own weight. The longest man made moving object was train making a one off train journey in Australia consisting of 8 AC6000 locomotives pulled 682 wagons loaded with iron ore, the train weighed circa 100,000 ton and the cargo weighed about 80% of this weight. The train was 4.6 miles long

The largest manmade moving object on the earth is a oil and gas seismic survey vessel called the Ramform Viking and is produced by PetroGEO Services (PGS). And it collects more than 1.12 Terabytes of seismic survey data per day.

The surveyor with its 10 streamers at 120 m separation is more than a kilometer wide and more than 8 km long covering a surface area of 8.75 km2 at any time. Moving at a speed of 4.3 knots it is covering a total surface area of 215 km2 per day in full production. It represents the largest moving object on the face of the earth, bigger than any seismic spread ever deployed and bigger than anything else moving on land or at sea.

There are a number of different types of spleen cancers including lymphoma, non-Hodgkin's lymphoma and some types of T-cell lymphomas. Roughly 70,000 new cases of lymphoma are diagnosed each year in the US. These types of cancer can happen at any age.

Specialization allows a person to become skilled and efficient at a specific task; he or she will then be able to produce much more of a good (or service) at a higher quality by himself than many other unskilled laborers attempting to do the same thing. This allows others to specialize in another task.

For example, one person could specialize in making a wheel, another in making the frame of a car, another the engine, etc.. By specialization they can efficiently do their individual tasks and together produce more cars than if they each attempted to create every part of the car by themselves.

By definition, illegal immigration is migration of people across national borders in a way that violates the immigration laws of the destined country. The goal is generally upward mobility.

Illegal Immigration is common in areas such as the United States, Britain, France, and most of the well known Western world (Including Germany, to name a few)

Illegal Immigration is common include Japan, South Korea, and Australia.

Illegal Immigration often involves criminal syndicates. Russian & Italian Mafia in the Western World and the Chinese Triads are in main control in the Far East.

In the United States, the majority of illegal immigrations involve the Chinese Triads (Pacific), the Russian/Italian Mafia (East Coast), and Mexican Cartels (South)

Energy is given in Joules with is a Newton meter. A Newton is a kilogram meter squared per second squared. A 10 kg child has 98.1 Newtons which equals 98.1 Joules.

The difference between potential and kinetic energy all comes down to a very simple property of the object. If an object is moving, then it has kinetic energy, or kinetic energy is the energy of movement. Potential energy is energy that is stored in an object and can be released under the right conditions.

Generally speed. But also, if the obect is for example travellin up, the potential energy also increases.

80 mph = 128.75 km/h

One liter per day equates to 4.16666667 × 10-5 cubic meters per hour.

The free fall of the object in gravitational field changes its gravitational potential energy to kinetic energy

When you drop a rock and it hits the side walk it makes a sound. Kinetic energy transferred to sound energy.

10 mph or 16 km/h

inc temp, increases the ave. KE of the particles.

116 kmh in equivalent to 72 mph or 32.2 metres/sec.

In this context "conserved" means the total kinetic energy of all the objects is the same after the collision as before the collision. Note, the TOTAL is the same but the individual kinetic energies of each object may be different before and after. When two or more objects are about to collide they have a certain total kinetic energy. It is common that during the collision some of the kinetic energy is transformed into heat. So after the collision the total kinetic energy is less then before the collision. This is a non-elastic collision. There are some collisions, however, in which none of the kinetic energy is changed to heat. These are called ELASTIC collisions. So the total kinetic energy doesn't change, or is "conserved". There is another possible non-elastic collision. If during the collision there is an explosion, then its possible for the objects to have a larger total kinetic energy after the collision as they aquire some of the explosive energy. Finally note, that in all collisions the TOTAL vector momentum is the same just before and just after the collision. So in a collision momentum is always conserved.

Ofcourse, actually, you have to have mass in order to calculate kinetic energy.

Kinetic Energy = 0.5*m*v^2

Where m is the mass.

Where v is the velocity.

Mass is directly proportional to the kinetic energy, the more the mass, the more the kinetic energy.
