The answer is true due to the fact that "peak" is another way of saying "top" and in this case its the MAX number of people traveling.
We have negative acceleration when an object projected upwards, while positive acceleration is a free fall.
vf^2 = 2ad
vf^2 = 2(9.81)(44m)
vf^2 = 863.28
vf = √863.28
vf = 29.4 - using equations of motion
ME = PE + KE
ME = mgh + 1/2mv^2
ME = (1)(9.81)(44) + 1/2(1)(3^2)
ME = 431.64 + 4.5
ME = 436.14 - using conservation of energy
hope this helps :)
Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that
Potential well dimension =
Mass of electron
So energy required to electron to jump from ground state to 3rd state
Ptolemy's model theorizes that Earth is the center of the universe, and that all planets and the Sun revolve around it. If Venus is between the Earth and the Sun, then the Venus must always be crescent or all dark. <em>Thus, it is impossible to see a full or gibbous face of Venus. </em>Later on, this was disproved by Galileo when he saw through the telescope all phases of Venus. Hence, the heliocentric theory was approved instead.
