Salt is the solute in that situation
Answer:
Maximum acceleration will be equal to 
Explanation:
We have given coefficient of kinetic friction 
And coefficient of static friction 
Acceleration due to gravity 
When truck moves maximum force will be equal to 
It is given that half of the weight is supported by its drive wheels
So force required 
From newtons law maximum acceleration will be equal to 
Answer:
The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object. The frictional force from a fluid is called a drag force.
Explanation:
Reading of the scale will be given as Normal force on the man
So here we can say that
weight of the mas will be

normal force on the man will be given as

now net force is given by Newton's II law




a = 3.33 m/s^2
so elevator is accelerating downwards with an acceleration a = 3.33 m/s^2
Answer:
We need to multiply 12 to each term to eliminate fractions.
Explanation:
Given expression:

To eliminate the fraction we need to multiply each term by least common multiple of the denominators of the fraction.
The denominators in the above expressions are:
4, 3 and 2
The multiples of each can be listed below.
2⇒ 2,4,6,8,10,<u>12</u>,14,16.....
3⇒ 3,6,9,<u>12</u>,15,18
4⇒ 4,8,<u>12</u>.......
From the list of the multiples stated, we can see the least common multiple is 12.
So we will multiply each term by 12.
Multiplying 12 to both sides.

Using distribution,

Thus we successfully eliminated the fractions.
