(D) Mass and energy can convert to one another.
From the experiment it can be concluded that a material or object which has a density that is lesser than water floats. Also, the object that has a density greater than that of water will sink. This is because density is the measure of the amount of substance that is occupied by an object in a given volume.
Answer:
4: Hydro electrical energy
5:Flase the law of conservation of energy is not violated by transformer.
Explanation:
4:Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
5:Quantum Physics and Law of Conservation of Energy.
Niels Bohr, Hans Kramers, and John Slater proposed that these electrons violated the law of conservation of Energy momentarily. They stated that with each jump, energy is either created or destroyed by the electrons during the whole process.
Oh this is extremely hard...i might just die lol jk its the last one measuring cylinder :)
Answer:
Use bags that are not of plastic and that we can reuse.
Explanation:
To reduce the number of petroleum, people should use everyday things that do not have plastic in their composition. For example, drink water from a flask made of iron, take your mug to the coffee store or use cloth bags. These elements are not disposable, and we can use them multiple times, which leads to a reduction in the consumption of plastic products and the amount of petroleum needed for their production.
