Answer:
The value of acceleration due to gravity on all objects near the surface of earth will be 9.8 m/s/s or 10 m/s/s(approx)
Explanation:
here we know that all objects near the surface of earth will experience the force of gravity towards the center of earth.
this force of gravity is given as

now to find the acceleration due to this force we can say

here we will have


so acceleration due to gravity for all objects near the earth surface is nearly same or constant
Before going to answer this question first we have to understand Newton's third law.
As per newtons third law ,for every action,there is an equal and opposite reaction.The force exerted by a body on other body is called action and force that the body gets in turn is called reaction. They will always act on two different bodies and their direction will be opposite to each other.
As per the question a object is falling under gravity. We are asked to find out the action and reaction forces.
We know that every object having mass will imparts gravitational forces on each other.In this question the earth will apply the force of gravity on the body which is in vertically downward direction.Due to this gravity,the body will fall towards earth with an acceleration of 9.8 m/s^2 .This is the force of action.
The falling object also applies same amount of force on earth in vertically upward direction.But we will not notice any acceleration of earth.It is so because the earth is very massive, so the acceleration produced by earth is very small.The force exerted by the falling object on earth is the force of reaction.
Answer:
yes
Explanation:
The solubility of glucose at 30°C is
125 g/100 g water. Classify a solution made by adding 550 g of glucose to 400 mL of water at 30°C. Explain your classification, and describe how you could increase the amount of glucose in the solution without adding more glucose.
Answer:
With a 50-mL graduated cylinder, read and record the volume to the nearest 0.1 mL. The 10-mL graduated cylinder scale is read to the nearest 0.01 mL and the 500-mL graduated cylinder scale is read to the nearest milliliter (1 mL). A buret is a scaled cylindrical tube attached to a stopcock, or valve.
Answer:
The atoms ,molecules, or compound present at the start of a chemical reaction that parcitipate in the reaction are <u><em>the reactants.</em></u>
Explanation:
The chemical reaction is the way in which one substance reacts against another. So, a chemical reaction consists of the transformation of some substances into others, that is, the process of arranging atoms and bonds when chemical substances come into contact.
In a chemical reaction, the initial substances are called reactants, while the new substances obtained are called products.
So, <u><em>the atoms ,molecules, or compound present at the start of a chemical reaction that parcitipate in the reaction are the reactants.</em></u>
