Answer:
the energy emission process is due to nuclear fusion
Explanation:
In the planetary system the energy emitted by bodies is a part of the energy received by a hot body (star), this star is what creates the entire energy cycle of a given planet. This creates the entire tidal movement, continental drift
If the planets reach a certain size the gravitational force near their center is so great that the atoms are crushed and some beginnings of fusion processes are formed where some atoms are transformed from hydrogen to helium releasing a certain amount of energy and heat that believe that the planet emits more energy than it receives from its star.
In summary, the energy emission process is due to nuclear fusion
Acceleration is defined as the change in velocity divided by the change in time. Since the velocity changed from 50 m/s to 40 m/s (-10 m/s change) in 2 seconds, then the acceleration is (-10/2) = -5 m/s^2 northward. Hope this helps!
Answer:
1.29 moles
0.753 moles
0.745 moles
Explanation:
PV=nRT
n=PV/RT
n=(1)(34.2)/(0.0821)(323.7)
n=1.29
n=PV/RT
n=(1)(22.4)=(0.0821)(362.15)
n=0.753
n=PV/RT
n=(1)(16.7)/(0.0821)(273.15)
n=0.745
In the ideal gas equation, T is measured in Kelvin.
Answer:
The star-sphere discovered by the Greeks and other ancient civilizations which shows the physical location in space of the nearby stars.
Explanation:
The celestial sphere is an ideal sphere, without defined radius, concentric with the terrestrial globe, in which the stars apparently move. Some ancient civilizations such as the Greeks assumed that the stars were attached to a celestial sphere, which revolves around the earth, while our planet is always immobile.
Answer:
move upward with increasing speed
I draw fbd diagram , see in figure
when lift going upward -
F - mg = ma
f = m( a + g)
scale so highest reading
