The Greenhand degree is for first year or freshmen high school students. To receive the Greenhand degree, affiliates must have acceptable plans for a Supervised Agricultural Experience Program (SAEP) and make evident knowledge of the principle, code of ethics, motto, salute emblem, official dress, and important dates in FFA history. The Greenhand degree pin is made out of bronze for its strength and stability or durability.
Answer:
it seems that the answer should be 7.5 mph as the average
Explanation:
sorry i did (s x t) when it was (s/t)
First we have to convert 6 grams to kg (0.006 kg) and then using the thermal physics formula which is Q=m*c*change in temperature, we get 478,8 joule
(Btw c is the specific heat capacity of water which is 4200 j/kg °C
Answer:
Explanation:
By conservation of energy, the sum of the kinetic and gravitational potential energies at the surface of the Earth must be equal than their sum at infinity, so we have:
Where 
is the gravitational constant,
and 
are the mass and radius of the Earth, <em>m </em>is the mass of the particle, 
its velocity at the surface of the Earth (which would be its escape velocity) and 
and 
are the velocities and distance at infinity, which would be null and infinity respectively, so the right hand side of our equation is 0J, which leaves us with:
Also, since the force the molecule experiments is the force of gravity (disregarding drag), we can write its weight in terms of Newton's Law of Gravitation:
Which means that:
So finally putting all together we can write:
An educated guess is a “hypothesis”
