Newton’s second law of motion

Chemistry
1 answer:
Fiesta28 [93]2 years ago
3 0

When an object of mass 2Kg and applied force is 10N then acceleration is 5 m/s/s.

<h3>What is Newton's second Law?</h3>

Newton's second Law of motion will be represented as:

F = m.a, where

  • F = force
  • m = mass of object
  • a = acceleration

Acceleration for the first row will be calculated as:

  • a = 10/2 = 5 m/s/s

Acceleration for the second row will be calculated as:

  • a = 40/5 = 8 m/s/s

Mass for the third row will be calculated as:

  • m = 20/5 = 4kg

Mass for the forth row will be calculated as:

  • m = 45/45 = 1 kg

Force for the fifth row will be calculated as:

  • F = (3)(3) = 9 N

Hence, acceleration of the object whose mass is 2kg and force on that object is 10N is 5m/s/s.

How can air pollution affect plants?
GarryVolchara [31]

Answer:

C. air pollution absorbs carbon dioxide

Explanation:

Carbon dioxide's role in the greenhouse effect is a major contributor to air pollution. Radiation and heat emanating from the earth's surface need to be released out into the atmosphere. But because carbon dioxide levels are so high, there is an ozone effect on the ground level.

How does distillation work.
Usimov [2.4K]

Answer:

Distillation is an important commercial process that is used in the purification of a large variety of materials. However, before we begin a discussion of distillation, it would probably be beneficial to define the terms that describe the process and related properties. ... Elevation of the boiling point with an increase in external pressure, while important in cooking and sterilizing food or utensils, is less important in distillation.

If you have a truckload of icecream, a bucket of sauce, a box of peanuts but only 1 cherry, you can only make 1 complete sundae.
MAXImum [283]

Answer:

<em>Only 5 sundaes can be made</em>

<em>The limiting reagent is the peanuts.</em>

Explanation:

The complete question is

A perfect ice cream sundae requires exactly:

• 3 scoops of ice cream

• 2 squirts of chocolate sauce

• 1 spoon of peanuts

• 1 cherry

If you have 7 scoops of ice cream, 3 spoons of peanuts, 5 cherries and 11 squirts of sauce, you can only

make 2 complete sundaes. In this case, the icecream is the limiting reagent.

If you have a truckload of icecream, a bucket of sauce, a box of peanuts but only 1 cherry, you can only  make 1 complete sundae. In this case the cherry is the limiting reagent.  The limiting reagent is the term given to the ingredient (read: reactant) that has the (stoichiometrically) least  amount. The other reactants are said to be in excess. In a reaction the limiting reagent will be totally  consumed, and some of the reactant in excess will be leftover.

Critical thinking questions

1. If you have 20 scoops of ice cream, 14 squirts of chocolate sauce, 5 spoons of peanuts and 7 cherries,

how many sundaes can you make and which ingredient is the limiting reagent?

From the ingredients for a a complete sundae given above,

20 scoops of icecream will make 20/3 = 6.66 sundaes

14 squirts of chocolate sauce will make 14/2 = 7 sundaes

5 spoonful of peanuts will make 5/1 = 5 sundaes

7 cherries will make 7/1 = 7 sundaes

From the above, we can work out that only 5 sundaes can be made, and the limiting agent here is peanuts, which has the least amount of sundae that can be made from its available amount.
