Answer:
IGNEOUS ROCKS
Explanation: Igneous rocks are those rocks that solidify from magma.
Igneous rock is divided into two ,they are:
1. Intrusive
Igneous rocks crystallized belowearth"s crust. Its cooling material is called lava.
2 Extrusive igneous rock is also known as known as volcanic rocks
Answer:
when an electron made a transition from an outer orbit to one closer to the nucleus
Explanation:
Bohr amended that view of the motion of the planetary electrons to bring the model in line with the regular patterns (spectral series) of light emitted by real hydrogen atoms. ... Light, he proposed, radiated from hydrogen atoms only
The answer to your question is "20kgx9.8m/s" because weight is the force an object is exerting on another object, and the formula used to calculate force is <em>Force = Mass * Acceleration</em>.
Let V = the volume of the balloon
Force of gravity = V * ?hot * g downward
Buoyant force = V * ?cool * g upward
Net upward force F = V * ?cool * g - V * ?hot * g
F = V g (?cool - ?hot)
Mass of the balloon m = V ?hot
a = F/m = V g (?cool - ?hot)/(V ?hot)
a = g(?cool/?hot - 1)
a = 9.8(1.29/0.93 - 1)
a = 3.79 m/s^2
<span>Answer is 3.79 m/s^2</span>
