How does a planet’s orbital radius relate to its period?
Volgvan

Answer:

hope this helps :)

Explanation:

Kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi major axes of their orbits. Kepler's Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit.

What steps do you take to make a good science fair project?
Irina-Kira [14]

   Pick a topic.

   Research.

   Hypothesis.

   Experiment.

   Construct an exhibit for results.

   Write a report.

   Practice presenting.

Pick something you are interested in, something you'd like to think about and know more about

Then do some background research on the topic.

Decide whether you can state a hypothesis related to the topic (that is, a cause and effect statement that you can test), and follow the strict method listed above, or whether you will just observe something.

Design and carry out your research, keeping careful records of everything you do or see and your results or observations.

Construct an exhibit or display to show and explain to others what you hoped to test.

Write a short report that also states the same things as the exhibit or display, and also gives the sources of your background research.

Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.

Explain the global water crisis in your own words​
makvit [3.9K]

Explanation:

Water is the basic necessity of every human being. But, water scarcity is a major issue that is rising very rapidly in modern-day India. The problem has become so severe that in many states the groundwater has almost dried up and people have to depend on water supply from other sources. In addition, water is one of the most misused commodities that we still waste. It is the central point of our lives but not the central point of our focus.

In the past, people understand the value of water and plan their lives around it. Moreover, many civilizations bloom and lost on account of water. But, today we have knowledge but we still fail to understand the value of water.

Reason for Water Scarcity in India

Water scarcity is the cause of mismanagement and excess population growth of the water resources. Also, it is a man-made issue that continues to rise. Besides, some of the reasons for water scarcity are:

Wasteful use of water for Agriculture- India is one of the major food growers in the world. That produces tons of quantity of food to feed its population and export the surplus that is left.

In addition, producing this much food requires a lot of water too. The traditional method of irrigation wastes a lot of water due to evaporation, water conveyance, drainage, percolation, and the overuse of groundwater. Besides, most of the areas in India use traditional irrigation techniques that stress the availability of water.

But, the solution to this problem lies in the extensive irrigation techniques such as micro-irrigation in which we provide water to plants and crops using a sprinkler or drip irrigation.

Reduction in water recharge systems- Due to rapid construction that uses concrete and marbles do not let the rainwater to get absorbed in the soil. But, if we install some mechanism in our houses that can hold the rainwater then we can recharge the groundwater.

Lack of water management and distribution- There is a need for an efficient system that can manage and distribute the water in urban areas. Also, the government needs to enhance its technology and investment in water treatment. Besides, we should ensure optimization at the planning level.

Solutions to Overcome this Problem

Water-free urinal- Urinal waste around 6 liters of water per flush that add up to 25 thousand liters per year. If a male member of the house stops using the flush then they can save lots of water.

Close the running tap- During dishwashing and hand washing people often let the tap running. These running taps waste thousands of liters of water per year. Besides, closing the tap will reduce this problem.

Replace dripping taps- In India it is commonly seen that most of the houses have one or two taps that drop water even when they are close. This running tap wastes up to 30,000 liters of water that nobody bothers to change. So, we should replace these taps immediately.

To conclude, water scarcity has become a more dangerous problem day by day. Also, due to our leniency that we haven’t taken the problem water scarcity seriously. But, now the authorities and people are working to resolve this problem so that our future generations do not have to buy this necessity.
