Delis cactus is the correct way to write it.
Protons and neutrons are in the Nucleus of an atom; electrons surround the nucleus through valance shells
<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg
The latent heat of vaporization for water is
2257 KJ per Kg . I'm pretty sure that's exactly
the same as 2257 joules per gram. So ...
When 1 gm of STEAM at 100 C condenses to
1 gm of liquid water at 100 C, it releases
2257 joules of heat energy to its environment.
Answer:
10m/s
Explanation:
a = v- u/ t
=> v = at + u
= -2 × 5 + 20
= 10m/ s. ( 72 km/ h = 20 m/ s)
