(Fall of Man) when Adam and Eve ate of the fruit of the tree of knowledge of good and evil in the Garden of Eden, God punished them by driving them out of the Garden of Eden and into the world where they would be subject to sickness and pain and eventual death.
A pressure antinode in a sound wave is not a region of high pressure, while a pressure node is not a region of low pressure.
The answer is false
Explanation:
Rutherford proposed a revised model for the atom, called the planetary model. The previous model of the atom was Thomson's Plum Pudding Model which consisted of freely moving positive and negative charges inside the atom.
Rutherford proposed his model after an experiment he conducted called the Gold Foil Experiment. This experiment consisted of a thin gold sheet into which alpha particles were shot upon and they were detected by a sensor. The image attached will give a better explanation of this. In this experiment he shot a beam of alpha particles(helium nucleus) at a thin sheet of gold. Rutherford hypothesised that there should be minimum deflection of the positively charged alpha particles occuring due to the repulsion of the alpha particle with the positive charges in the thin gold sheet. This was not the case.
However what he found was that most of alpha particles went straight through the thin sheet of gold but some were reflected back to him. This surprised him. Hence he proposed that most of the atom must be empty space as most of the alpha particles went straight through the sheet and there must be a heavy nucleus inside the atom causing the alpha particles to bounce back.
Answer:
226.6 N
Explanation:
The work done by the push is given by:
where
p is the magnitude of the push
d is the displacement of the crate
is the angle between the direction of the push and the displacement of the crate
On the contrary, the work done by the frictional force is:
where
is the frictional force, with m=1.00x102 kg being the mass of the crate ang g=9.81 m/s^2 the gravitational acceleration
d is the displacement of the crate
the negative sign is due to the fact that the frictional force acts in the opposite direction to the displacement of the crate.
The net work must be zero, so:
Substituting the previous equations into this one, we find:
which we can solve to find p:
Answer:
6.7 x 10^8 mi/hr
Explanation:
Do the math with units ONLY
km/s * miles/ km * s/hr = mi / hr ( ...as the km and s cancel out)
now.... put in the numbers
3 x 10^5 km/s * .62 mi/km * 3600 s / hr = 6.7x 10 ^8 mi/hr
