You and your lab group have been asked to design an investigation to determine the effects of heat transfer between two different objects. Which of the following investigation designs explains the heat transfer when atoms directly touch?.

Answers

Answer 1

There are different ways for transfer of heat. investigation designs explains the heat transfer when atoms directly touch is Hands touching the handle of pan sitting on a lit Bunsen burner.

In conduction, When two objects touch, heat from the hotter object is said to be transferred to the cooler object.

Heat as a flow of energy often arise from a higher temperature object to a lower temperature object.

The temperature that exist difference between the two neighboring objects can lead heat transfer.

The heat transfer is still ongoing until the two objects have attained thermal equilibrium and are found in the same temperature.

I am thinking of two positive numbers in the ratio $5:3$. The difference between the two numbers is $90$. What is the sum of the two numbers?.

Answers

The sum of the two numbers is $ 360

Let the bigger number be x

Let the smaller number be y

From the question given above, we were told that two numbers exist in ratio $ 5 : $ 3

Thus,

x : y = 5 : 3

x/y = 5/3

Cross multiply

x = 5y/3 ............ (1)

Also, we were told from the question that difference between the two numbers is $ 90 i.e

x – y = 90 ........... (2)

Substitute the value of x in equation (1) into equation (2). We have:

x = 5y/3 ............ (1)

x – y = 90 ........... (2)

5y/3 – y = 90

Multiply through by 3

5y – 3y = 270

2y = 270

Divide both side by 2

y = 270 / 2

y = $ 135

Substitute the value of y into equation 1 to obtain the value of x.

x = 5y/3 ............ (1)

y = $ 135

x = (5 × 135)/3

x = 675 / 3

x = $ 225

Finally, we shall determine the sum of the two numbers.

x = $ 225y = $ 135Sum =?

Sum = x + y

Sum = 225 + 135

Sum = $ 360

Thus, the sum of the two numbers is $ 360

What has the smallest effect on the rate of photosynthesis.

Answers

Answer:

Light intensity

Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.

The smallest effect on the rate of photosynthesis is typically the availability of carbon dioxide (CO2).

Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen.

Other factors that can influence the rate of photosynthesis to a greater extent than carbon dioxide include:

Light intensity: The rate of photosynthesis increases with higher light intensity, up to a certain point. Beyond that point, called the saturation point, increasing light intensity does not further increase the rate of photosynthesis.

Temperature: Photosynthesis is a temperature-dependent process. Within an optimal temperature range, the rate of photosynthesis increases with higher temperatures.

Water is essential for photosynthesis as it provides the medium for chemical reactions to occur. Inadequate water availability can lead to a decrease in photosynthesis.

Therefore, while all the factors mentioned (light intensity, temperature, water availability) can significantly impact the rate of photosynthesis, the availability of carbon dioxide generally has the smallest effect.

There are four mistakes spotted in the sentence.Firstly, Mrs. Hendrics is asking for the books. So, it will be "asked" instead of "said" but still you can write it "said" only. But if it was in indirect speech, it must be "asked".Secondly, you haven't given a comma after said. You must give so.Thirdly, the w of where should be in capital. Lastly, you have written the "?" after the double quotes. You should write it before the quotes. So the correct sentence will be:Mrs.Hendrics asked, "Where are the books?"

A 1. 5-kilogram lab cart is accelerated uniformly from rest to a speed of 2. 0 meters per second in 0. 50 second. What is the magnitude of the force producing this acceleration?.

Answers

The magnitude of the force producing this acceleration is found to be 3.0 N.

What is Force?

Force may be defined as the process of pushing and pulling an object with an appropriate mass in order to cause it to change its velocity with respect to time.

Force is a vector quantity as it has both magnitude and direction. Force is an external agent which is generally capable of changing a body's state of rest or motion with respect to time.

According to the question,

The total mass of an object = 1.5 kg.

The speed of an object = 2.0 m/sec.

So, the formula for calculating the magnitude of the force is as follows:

Force = Mass × Acceleration.

                   = 1.5 kg × 2.0 m/sec = 3.0 N.

Therefore, the magnitude of the force producing this acceleration is found to be 3.0 N.

Which of the following would have the largest concentration of chloride ions in solution.

Answers

Answer:

From the given options, the solution of 0.10M AlCl₃ is the one that has the highest concentration of chloride ions.  

To know which of the given solutions has the highest concentration of chloride ions, we must evaluate each of them.

1) 0.10 M MgCl₂

We can see that in 1 mol of MgCl₂, we have 1 mol of Mg²⁺ and 2 moles of Cl⁻ ions, so if the initial concentration of MgCl₂ is 0.10 M we have:

 

Hence, in this solution we have 0.20 M of chloride ions.

2) 0.10 M AlCl₃

In 1 mol of AlCl₃, we have 1 mol of Al³⁺ and 3 moles of Cl⁻, so the concentration of Cl⁻ is:

 

Then, the concentration of chloride ions in this solution is 0.30 M.

3) 0.05 M CaCl₂

We can notice that in 1 mol of CaCl₂ we have 1 mol of Ca²⁺ and 2 moles of Cl⁻. The concentration of Cl⁻ is:

So, the concentration of the Cl⁻ ions is 0.10 M.

4) 0.10 M LiCl

In this case, in 1 mol of LiCl we have 1 mol of Li⁺ and 1 mol of Cl⁻, so the concentration of the chloride ions is:

Hence, in this solution the concentration of the Cl⁻ ions is 0.10 M.

Therefore, the solution 0.10M AlCl₃ has the highest concentration of chloride ions.
