Answers

Answer:

6.93 km/h

Explanation:

To calculate her average speed, we need the "speed" formula, which is:

average speed = distance / time

You plug in your numbers and it will give you the answer.

Speed = 4.5km/0.65hr

           = 6.923 km/h

Will the net force be greater or lesser for objects with greater mass?

Answers

The net force will be lesser for objects with greater mass

Answer:

The answer is

→ If an object has a greater mass, then the net force will be lesser.

Explanation:

The net force will be lesser because the greater mass the object is, the slower the net force will be.

If we were to talk about lesser mass in an object, then the net force will be faster, but this isn't the case right now.

Answer:

Your Best Answer would be C

Hope this helps :)

Charlotte's control group in this experiment would be: not rubbing the cloth against the PVC pipe or the paper. Option (c) is correct.

What is control group in the experiment?

In a scientific experiment, a control group is a subset of participants who are not included in the main experiment and whose outcomes are unaffected by the independent variable under study. By isolating the effects of the independent variable on the experiment, this can help rule out other possible explanations for the findings of the experiment.

Positive and negative control groups are the other two categories into which they might be divided.

Not all scientific studies call for the use of control groups. The use of controls is crucial when an experimental conditions are complex and difficult to isolate.

What is the net force acting on the object above?

Answers

5 N to the right

There’s a force of 6 N pulling to the right (the positive direction) and 1 N pulling left (the negative direction).
Net force= 6 N - 1 N = 5 N to the right

Answer:

5N to the right

Explanation:

You have a force of 2N acting on the object to the right, 1N to the left, and another 4N to the right. if we add all of these forces together, taking to the right as positive, and to the left as negative, we get 2 + 4 - 1, which is 6 - 1, which is equal to 5, and since it's positive, it's a net force to the right.

Do all types of light change materials in the same way

Answers

Transparent and translucent materials transmit most of the light that strikes them, but not all of it. Light can also
reflect off these materials. When light reflects, it is bouncing off something. Windows transmit most of the light that strikes them, but they also reflect light. If you have a lamp turned on near a window at night, you can see the reflection of the lamp in the window.
Transparent and translucent materials also absorb some of the light that strikes them. When something absorbs light, it is soaking up the light. When light is absorbed by an object, the light energy changes to heat energy and the object heats up. If you touch a window that has been in the sunlight, you will notice that it is warm.
Opaque materials do not transmit any light. All of the light that strikes an opaque material is reflected or absorbe
Light can be reflected, transmitted, or absorbed. You have read that EM waves can interact with a material medium in the same ways that mechanical waves do. Most things are visible because they reflect light. The two other forms of interaction are transmission and absorption.

Read the speech and answer the question.Voluntourism: An Opportunity Too Good to be TrueA Speech to the Student Body of Evergreen High[1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference.[2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help."[3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved.[4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels).[5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour.[6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.How does the speaker's metaphor of the mirage in paragraph 4 support the purpose of the speech? It develops the idea that voluntour opportunities are not what they appear to be. It emphasizes the idea that voluntour work is difficult and draining but worth the effort. It reveals the significant contribution that voluntours make to the areas they visit. It shows that voluntourism experiences can even take place anywhere-even in the desert.
