Answer:
Electrical energy
Explanation:
electrical energy Essentials. A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
Answer:
gathered by using measurement tools and math
Explanation:
Quantitative data is often gathered by using measurement tools and math.
A quantitative data set is assigned values and numbers in order to solve a problem or for the purpose of a study.
- Each data set has a unique numerical value and can be counted.
- Qualitative data set does not use numerals and numbers.
- It engages the senses to make some scientific deductions.
- Examples are measurement of volume, distance, length, time, number of moles e.t.c
- Qualitative data sets include taste, smell, color e.t.c
Answer:
b) There is and always will be the exact same amount of energy in the universe.
Explanation:
The first law of thermodynamics establishes the principle of energy conservation, that is to say that in any process the energy is not destroyed, it only transforms into another type of energy, so when analyzing thermodynamic systems it is established that the energy that enters A system is the same that comes out. For the above reason, it can be inferred that if the energy is not destroyed or created there will always be the same amount of energy in the universe.
The mantle. It is also the largest earth layer, making up about 84% of the earth.
Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.
