Answer: B) a newton-meter and a joule

Explanation:

Joule is the unit if energy. One joule is equal to one Newton-meter.

1 J = 1 N-m

Energy is equivalent to work done which is equal to dot product of force and displacement.

E = W = F.s

Energy is measured in Joules. Force is measured in Newtons and displacement is measured in meters.

1 Joule = 1 kg m²/s²

1 N = 1 kg m/s²

1 N-m = 1 kg m/s² × m = 1 kg m²/s² = 1 J

Answer : The correct options are, (B) a newton-meter and a joule and (C)  a newton and a joule/sec

Explanation :

As we know that,

1N=1Kg\text{ m }s^{-2}\\\\1J=1\text{Kg }m^2s^{-2}\\\\1W=1\text{Kg }m^2s^{-3}

or we can say that,

1W=1J/s\\\\1J=1Nm\\\\1N=1J/s\\\\1W=1Nms^{-1}

From the given options, the option B and C are the equivalent units.

Hence, the correct options are, (B) and (C)

In a swimming meet, the swimmers swim a total of 8 laps of a 50-meter-long swimming pool. What is the distance traveled by a swi
N76 [4]

Answer:

The swimmer has a distance traveled of 800 meters.

The final displacement of the swimmer is 0 meters.

Explanation:

A lap is a round trip made by a swimmer in the pool, so that the distance traveled by swimmer is sixteen times the length of the swimming pool. That is:

s = \left(2\,\frac{travels}{lap} \right)\cdot \left(8\,laps \right)\cdot \left(50\,\frac{m}{travel}\right)

s = 800\,m

A swimmer has a distance traveled of 800 meters.

The displacement is the distance between swimmer and a reference point, let suppose that reference point is located at the beginning of the first lap. Hence, the final displacement of the swimmer is 0 meters.

which of the following statements best justifies the inclusion of test tube v as a control in the experiment? responses it will
prohojiy [21]

The following statement which best justifies the inclusion of test tube v as a control in the experiment is that it will show the color change that occurs in the absence of enzyme activity and is denoted as option C.

<h3>What is an Enzyme?</h3>

This is referred to as a biological catalyst which is involved in the speeding up of the rate of a reaction by lowering the activation energy used to initiate the reaction.

Enzymes are known as proteinous in nature and are denatured by heat and other substances is included in the test tube v as a control in the experiment is that it will show the color change that occurs in the absence of enzyme activity.

This therefore helps to differentiate the enzymatic processes which takes place in a substance or body therefore making option C the correct choice.

The options are:

  • It will provide a measurement of amylase activity at an acidic pH.
  • it will provide a measurement of amylase activity at a basic pH.
  • It will show the color change that occurs in the absence of enzyme activity.
  • it will show the color change that occurs in the absence of the amylase protein.

It will show the color change that occurs in the absence of enzyme activity.
