wave has a frequency of 5hz and a wavelength of 25 m/s.
what is the speed of the wave

Answers

Answer:

125m/s

Explanation:

speed= wavelength×frequency

= 25×5

=125

The speed of the wave will be 125 m/s.

What is speed?

The magnitude of an object's rate of change of position with time, or the magnitude of change of position for each unit of time, is its speed; it can be considered as a scalar quantity.

Speed = wavelength × frequency

Calculation of speed is shown below:

It is given that wavelength = 25 m/s, frequency = 5 hz.

Speed can be calculated by using the formula:

Speed = wavelength × frequency

speed = 25m/s × 5 hz

speed = 125 m/s

How cations can become neutral atoms?

Answers

A neutral atom contains the same number of electrons as protons and that means that the electric charge of the atom is neutral or otherwise known as zero. However, if a particular atom loses an electron, the atom becomes positively charged because there is more protons than electrons.
THIS IS CALLED A CATION.

Answer:

By gaining elections

Explanation:

Cations are formed when neutral atoms loss electrons and when they gain back the lost electrons the charges are neutralized.

Stop Wasting Food and Save the Planet "Wasted food" is food that is unspoiled, nutritious, and wholesome but is disposed or thrown away. This food may come from cafeterias, restaurants, factories, or grocery stores. By reducing the wastage of such food, we can help the environment in many ways. When we throw away good food, resources such as labor, gasoline, water, fertilizers, land, and energy are wasted as well. This means that by throwing away consumable food, we are throwing away helpful resources as well. Also, when good food is dumped in landfills, the nutrients in the food are not absorbed by the soil, and instead, the food rots and produces a gas called methane. Methane is a greenhouse gas that heats up the atmosphere and is one of the major causes of global warming. Some of the ways in which we can stop the wastage of consumable food and resources is by finding ways to stop disposing of food in the first place. By donating consumable food to non-profit government organizations (NGOs), we can feed the poor and hungry and keep them from starving. Composting, which is a method of decomposition of solid waste, helps to convert food into manure that is free of chemicals. This is another way which helps to convert good food into manure that can be used in place of harmful chemical fertilizers for crops. Understanding the importance of not wasting good food and using appropriate measures to avoid wastage of food is a step toward saving our planet.20Select the correct answer.Which of these best summarizes this passage?A. "Wasted food" is food which is usually thrown away from cafeterias, restaurants, grocery stores, and food factories. People need to ensure that they are more cautious about wasting food.B. Wastage of good food is an environmental hazard that needs to be stopped. By using proper measures to stop wastage of good food, we can help save resources and the environment.C. Wastage of food causes large-scale damage to the environment and also to precious resources. This includes labor, gasoline, water, fertilizers, land, and energy.D. Stopping the wastage of food helps in more ways than one. For example, people can donate leftovers to various organizations that help to feed the poor and hungry. A car travels 30 m in 5 seconds.

In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion provides the best explanation for why algae proliferate in neighborhood ponds? 3)Blair expects an increase of 3% in her current annualsalary of $42,000.
