Because it gives us the abilitity to find planets that have decent temperatures relative to earths temp so we can determine if the planet even has a possiblilty to sustain life hope this helps
The force that one massive object exerts to attract another object is called gravity or gravitational pull.
Answer:
Explanation:
ΔE = Δm × c^2
where,
ΔE = change in energy released with respect to change in mass
= 1.554 × 10^3 kJ
= 1.554 × 10^6 J
Δm = change in mass
c = the speed of light.
= 3 × 10^8 m/s
Equation of the reaction:
2H2 + O2 --> 2H2O
Mass change in this process, Δm = 1.554 × 10^6/(3 × 10^8)^2
= 1.727 × 10^-11 kg
The change in mass calculated from Einstein equation is small that its effect on formation of product will be negligible. Hence, law of conservation of mass holds correct for chemical reactions.
Do you mean what order the Earth is in? The planets in order from closest to farthest from the sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto is technically just a dwarf planet but I'll include it anyways.
In my school, a student
who refuses to wear their uniform gets suspended.
<span>Our school is quite strict
when it comes to our uniform. If you get caught with your tie off, an undone
button or untucked shirt, you will get a 45-minute detention after school.
Sometimes, when a student doesn’t wear their school uniform and the security
guard or the discipline officer catches them, they may also be required to do
community service or have their ID confiscated. Most of the time, this is done
so a student would be a better person that follows the protocols set by an
institution, and this makes a student prepared for the real world, equipped
with good values.</span>
