Question

Calculate the pressure when a force of 5 N is applied on an area of 5 square centimetre ?

Answer 1

Answer:

Pressure can be defined as force per unit area.Its SI Unit is Pascal or N/m square

Given,

Force. =. 5N

Area. = 5cm =5/100m=0.05m

Pressure = ?

Pressure = Force / Area

= (5/0.05)N/m

= 100 N/m

or

= 100 Pascal = 100 Pa

Answer 2

Answer:

Explanation:

Most carbohydrate-rich foods have a high starch content. Carbohydrates are the most common source of energy for most organisms, including humans. We could get all our energy from fats and proteins if we had to. One gram of carbohydrate contains approximately 4 kilocalories (kcal), the same amount as protein.
