A student plans to measure the circumference of a balloon at various temperatures to determine how temperature affects the volume of a gas. What is the independent variable in this experiment?

Answers

Answer 1

Answer: I think the independent variable is the temperature, while the dependent variable is the size of the balloon. The factor that is held constant is the amount of air in the balloon. An identical balloon kept at the original temperature. Independent variable in an experiment is the variable that the experiment plans to change while the dependent variable is the variable whose value depends on the independent variable.

William is interested in exercising more, but does not feel he has the time. Write a short response explaining how he can find the time to exercise

Answers

Exercising doesn't mean you have to spend hours in the gym. Exercises can be done at the comforts of your home too, and there's plenty of exercise available, especially for those who have less time to do so. Just like for example, waiting time. While you are waiting for your clothes in the washing machine to finish, you may use this time to do some basic exercises such as running in place, jumping jacks or carrying weights. It may only take a few minutes, but performing these exercises in less time is better than not doing it at all.

Answer:

Finding time to exercise can be difficult, but it is important to consider time spent exercising as important time, as important as social commitments, work, and school. Therefore, effective strategies to increase time for exercise include scheduling blocks of exercise time, making people more aware of your exercise time, analyzing your schedule for the best time to exercise, pursuing activities that can be done from home, finding places to exercise that are close to home, work, or school, and finding a person with whom you can exercise.

Select the layers of Earth that are completely solid. A. crust B. inner core C. outer core D. lower mantle E. asthenosphere

Answers

Answer:

The correct answer would be A. crust.

The crust is the outermost layer of the earth which is composed of different types of rocks such as sedimentary, metamorphic, and igneous rocks.

It is completely solid and can be broadly classified into two types: continental crust and oceanic crust.

The thickness of the oceanic crust is about 5 km to 10 km. It is primarily composed of basalt, gabbro, and diabase.

The thickness of the continental crust is around 30 km to 50 km.

The crust forms lithosphere along with hard and upper mantle.
