Answer: A
Explanation:
Molecules speed up as heat is added
For example when water is heated as the water gets hotter the molecules speed up causing the water to boil and change phases into a gas (this is called evaporation)
In an ice cube the water molecules are frozen (barely moving compressed tight together) as the ice cube heats up the molecules start speeding up and moving further apart as the ice cube turns into liquid form. So as heat is added molecules speed up, move faster and spread further apart
An eclipse is a phenomenon of an astronomical object being obscured by something. In this case, it is the Moon that is being obscured from sunlight by Earth's shadow. Answer is D.
temperature rises ? specific heat capacity etc ...
Answer:
The value of acceleration of a stone in free fall is 
.
Explanation:
Given that,
Mass of the object, m = 0.9 kg
Weight of the object, W = 9 N
We need to find the acceleration of a stone in free fall. The weight of an object is given by :
W = mg
g is the acceleration of the stone in free fall
So, 
So, the value of acceleration of a stone in free fall is . Hence, this is the required solution.
0.3 is your answer, good luck!!!!
