The mass of an individual atom will not change unless the atom undergoes a nuclear change. The average mass of an element remains essentially staple as an average of the common isotopes. However the mass number of a sample of an element can and will change over time as the radioactive isotopes undergo nuclear changes.

Can the atomic mass of an atom of a particular element ever change? Why or Why not? Yes, can change and called isotopes. Isotopes have more neutrons that you have protons which makes mass larger.

Nuclear transmutation is the conversion of one chemical element or isotope into another. In other words, atoms of one element can be changed into atoms of another element by transmutation.

Nuclear Transmutation. In modern times, it has been discovered that lead can in fact be turned into gold, but not through alchemy, and only in insignificant amounts. Nuclear transmutation involves the use of a particle accelerator to change one element into another.

Transmutation or nuclear transmutation is a process that involves a change in the nucleus of an atom. When the number of protons in the nucleus of an atom changes, the identity of that atom changes as it is turned into another element or isotope. This transmutation process can be either natural or artificial.

cheetah

and deer make 3 feet high and 9 feet distant when ran. the diffrence b/w the two is cheetah cant hold for more then 5 minuts but deer can hold for long time. Despite weighing hundreds of kilograms — up to 500 pounds — tigers can reach top speeds of 49 to 65 kilometers per hour (35 to 40 miles per hour).

There are few, if any stats for the “average human” in anything. Top runners do a 2 hour 26.2 mile marathon, and 4 minute miles. So for long distances top runners do 13 to 15 mph sustained. For short sprints of 100m or 200m it can be faster.

Humans could perhaps run as fast 40 mph, a new study suggests. Such a feat would leave in the dust the world’s fastest runner, Usain Bolt, who has clocked nearly 28 mph in the 100-meter sprint. The new findings come after researchers took a new look at the factors that limit human speed.

Yes, 15mph is very fast for a runner as it equates to a 4-minute mile. 15mph represents the fastest a human can run, with extensive training, for a distance of 1 mile to 2 miles. Sprinters can run faster, but obviously for a much shorter duration. Usain Bolt has hit 28mph in the 100m sprint.

Average speed – indications Most cyclists can achieve 10-12 mph average very quickly with limited training. Reasonable experience, medium (say 40 miles): average around 16-19 mph. Quite competent club rider, some regular training likely, medium-long distances (say 50-60 miles): 20-24 mph.
