It typically take longer for a heavier object to slow down therefor, a train will take more time. <span />
The mathematical and proportional relationship between mL and
said us that
is equivalent to 1mL.
If the density is considered as the amount of mass per unit volume we will have to

here,
m = mass
V = Volume
Replacing we have that


As
we have that the density in g/mL is,

The correct option is PLUM PUDDING, SOLAR SYSTEM, ELECTRON CLOUD.
J. J Thompson was the scientist who proposed the plum pudding theory of atomic model. Neil Borh was the one who developed the solar system model of atomic theory while the electron cloud model of atomic theory that is presently been used was developed by an Australian scientist called Erwin Schrodinger.<span />
Answer:
4
Explanation:
All of them are significant figures
9.79395 m/s²
2.44228 m/s²
Explanation:
m = Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
r = Radius of Earth = 6371000 km
a) at h = 6400 m
g = 9.79395 m/s²
b) at h = 6400000 m
g = 2.44228 m/s² I believe
