What do you notice about the relationship between the force strength and the size of the velocity change? HELP MEEEEE

1 answer:

4 0

Answer: As mass is constant during free-weight resistance training, a greater impulse will result in a greater velocity. Therefore, as generation of force greater than the weight of the resistance increases higher movement velocities and decreased movement times result. (from google)

Explanation: hope this helps! :)

Suppose you have a bucket of sand containing 2.5 billion grains of sand (2.5 x 10 grains). Most of the grains of sand are white,

anzhelika [568]

Answer:

a. 5.0 x 10⁷ brown grains = 50 million

b. 5.0 x 10³ brown grains = 5000

Explanation:

The concentration of 2 % brown sand means we have for every 100 grains of sand 2 are brown.

We need to calculate the number of brown sand in the bucket as follows:

= 2.5 x 10⁹ billion grains of sand x (2 brown grains/ 100 grains of sand)

= 5.0 x 10⁷ brown grains

Likewise if the concentration of brown sand is 2.0 ppm, it mean that we have 2 brown grain per every million grains of sand.

= 2.5 x 10⁹ billion grains of sand x ( 2.0 brown grains/10⁶ grains of sand )

= 5.0 x 10³ brown grains

The answers make sense since a concentration of 1 part per million is ten thousandths of a 1 percent

Which term is used to describe the reactant that is used up completely and controls the amount of product that can be produced d

givi [52]

Answer: Option (c) is the correct answer.

Explanation:

A limiting reagent is defined as a reagent that completely gets consumed in a chemical reaction. A limiting reagent limits the formation of products.

For example, we have given 5 mol of A and the reaction is $2A + 4B \rightarrow 2AB$

Whereas when 4 mol B will react with 2 mol of A. Hence, 8 mol of B will react with 4 mol A as follows.

$\frac{2}{4} \times 8$ = 4 mol

As, the given moles of A is more than the required moles. Thus, it is considered as an excess reagent.

Hence, B is a limiting reagent because it limits the formation of products.

Thus, we can conclude that limiting reactant is the term used to describe the reactant that is used up completely and controls the amount of product that can be produced during a chemical reaction.

how can you find the common denominator and least commom denominator?? Help and thx i accedentaly clicked on the wrong subject

Marianna [84]

Common denominator - Find the Least Common Multiple of the denominators (which is called the Least Common Denominator).

Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator.

Then add (or subtract) the fractions, as we wish!

Least common denominator - You do the same thing for the common denominator
