Answer:
Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. A feather and a rubber ball dropped together. Air resistance causes the feather to fall more slowly, while the ball falls more fast.
A ball slowing down as it rolls across a carpet is an example of friction.
Friction is a force that slows down moving objects.
-The water washes it causing it to break
-How hot or cold it is matters.
-ice can get into cracks which causes it to crack
-????
Explanation:
The given data is as follows.
Boiling point of water (
= (100 + 273) K = 323 K,
Boiling point of solution (
= (101.24 + 273) K = 374.24 K
Hence, change in temperature will be calculated as follows.
= 374.24 K - 323 K
= 1.24 K
As molality is defined as the moles of solute present in kg of solvent.
Molality = 
Let molar mass of the solute is x grams.
Therefore, Molality =
m = 
= 
As, 
x = 
= 1321.29 g
This means that the molar mass of the given compound is 1321.29 g.
It is given that molecular formula is 
.
As, its empirical formula is 
and mass is 30 g/mol. Hence, calculate the value of n as follows.
n = 
= 
= 44 mol
Thus, we can conclude that the formula of given material is 
.
Answer:
Some areas of the body are more sensitive than others because they have more nerve endings. It hurts when you bite your tongue because the sides of your tongue have a lot of nerve endings that are very sensitive to pain! The tongue, lips, and fingertips are the most touch-sensitive parts of the body. The parts of your skin that need to be most sensitive like your fingertips and your lips have more receptor cells in them than others less sensitive areas. The least sensitive skin on the human body is found in the heel area. This is because there are very few nerves in the heel to feel things. If there were too many nerves in our heels then walking would be far too painful.
