This is true, The total energy when a body falls freely towards earth remains constant.
The ideal gas Law
PV = nRT
Where does this come from?
Robert Boyle found
PV = a constant
That is, the product of the pressure of a gas times the volume of a gas is a constant for a given sample of gas. In Boyle's experiments the Temperature (T) did not change, nor did the number of moles (n) of gas present. So Boyle found
PV = (nRT)
but did not explore the effect the temperature, or the number of moles would have on pressure and volume.
Jaques Charles found
V = (a constant) T
That is, the volume of a given sample of gas increases linearly with the temperature if the pressure (P) and the amount of the gas (n) is kept constant. So Charles found
V = (nR/P) T
Avagadro's Postulate
At the same temperature and pressure equal volumes of all gasses contain the same number of molecules.
V = n (a constant)
V = n (RT/P)
Hope that helps!!!! : )
Answer:
Yes if it continues in that direction.
Explanation:
Answer:
0.75Hz
Explanation:
Given parameters:
Speed of the wave = 3m/s
Wavelength = 4m
Unknown:
Frequency of the wave = ?
Solution:
The speed of a wave is given by the expression below:
Speed = frequency x wavelength
Frequency =
=
= 0.75Hz
Answer:
See the explanation below
Explanation:
Student c's belief is fulfilled only for the movement of the earth with respect to the sun. But it has no validity or does not exist when it is necessary to explain other physical phenomena with respect to other satellites. For example, how would you explain the phases of the moon, if the Earth is located in the center of the Galaxy?, another serious question regarding the observations made by scientists millions of years ago, where they observed that the distances of the Earth from other planets were changing, with respect to time. If the Earth was in the center, all the planets and the sun would revolve around it preserving a constant distance (radius), at all times.
Other phenomena to explain would be the seasons on Earth, these are due to the axis of inclination of the Earth and the rotation of it around the sun.
