Answer:
Earth is an active planet. Its surface is made up of many individual plates that move and interact, Volcanoes and earthquakes both result from the movement of tectonic plates.
Explanation:
NONE of the choices is a correct answer.
Density is (mass) DIVIDED BY (volume).
The volume of the black cube is
2 x 2 x 2 = 8 cm^3
It's density is 48/8 = 6 gm/cm^3
The volume of the yellow cube is
3 x 3 x 3 = 27 cm^3
Its density is 135/27 = 5 gm/cm^3
The black one is denser because the RATIO of its mass to its volume is greater.
The cubes are made of different substances.
The density only depends on the substance. It doesn't matter HOW MUCH of the substance there is. It's the RATIO that counts.
The black one would be denser even if one cube or the other was the size of a supertanker.
B precipitation,condensation,precipitation
Answer:
θ = 66.90°
Explanation:
we know that
I= intensity of polarized light =1
I_o= intensity of unpolarized light = 13
putting vales we get
⇒
therefore θ = 66.90°
Answer:
123.2 m/s after 28s
Explanation:
Vi= 0 m/s
a= 4.4 m/s^2
t=28s
Vf after 28s
To find Vf use your kinematics formula Vf=Vi+at
Vi is Zero so it gets removed and the equation becomes
Vf=at
Simply Plug and Solve
Vf= 4.4(28)
Vf=123.2 m/s after 28s
