Renewable resources are resources that can be used repeatedly. Examples are wood, wind power, and solar energy.
Nonrenewable resources are resources that cannot be replaced naturally. Examples are oil, coal, and minerals.
Answer:
wave velocity= frequency × wave length
=1×3
=3m/s
Explanation:
The distance covered by the wave in one second is equal to its wavelength, therefore,
wave velocity=wavelength/time period
OR wave velocity= frequency× wavelength
You can assume velocity as speed here.
Answer:
Explanation:
Hello,
In this case, since nitric acid is HNO₃ and strontium hydroxide is Sr(OH)₂ we can represent the balanced chemical reaction by equaling the atoms of strontium, nitrogen, oxygen and hydrogen at both reactants and products as shown below:
Best regards.
It is an endothermic reaction, as the product have more energy than the reactants. So, the answer would be A. Brainliest? Hope this helped!❤️
