If the force exerted on a sled is 100 N and the mass of the sled is 50 kg, what is the acceleration of the sled?

Anna35 [415]

<h3><u>Answer;</u></h3>

acceleration= 2 m/s²

<h3><u>Explanation;</u></h3>

From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.

That is;

F = ma

Thus; F = 100 N, m = 50 kg

a = F/m

= 100/50

= 2 m/s²

In the term trace element, the adjective trace means that

Margarita [4]

Answer:

The elemental is required in very small amount. (Ans. A)

Explanation:

Trace element is also known as micro-nutrient. It is also defined as any chemical element required by living organisms in a minute or small amounts which is usually part of the vital enzyme (cells produced by catalytic protein).

Exact needs of trace elements vary among species, like commonly required plant trace elements are cooper, zinc, manganese, boron, and molybdenum. Animals commonly required iodine, manganese, and cobalt.

Absence of necessary plant trace elements required by plants in the soil causes deficiency disease, lack of animal trace elements used by animals in the soil may not harm plants, but, animals feeding on those plants develop their deficiency disease.

So, the adjective trace means that the elemental is required in a very small amount.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct? a. The two

Mandarinka [93]

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

Answer:

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.
