electrical energy
Explanation:
electrical energy is caused by moving partial that have a negative or positive charge these purses are called electron current electricity is electrical energy that flows from one place to another usually through a wire electricity is a type of energy that comes from an electrical energy
Answer:
1. documenting, tinkering, testing
Explanation:
Technological design is defined as the process of study, design and development of new technologies.
There are some action in the methodical tests and refinements specific to technological design include documenting, tinkering, testing.
<u>Documenting </u><u>includes collecting all the information about the design and develop the product, </u><u>tinkering</u><u> involves repairing or adjust the issues found in the development, and </u><u>testing </u><u>helps to evaluate if the product is ready to work as it is supposed to.</u>
Hence, the correct answer is "1."
Answer:
180.87 °C
Explanation:
Applying pressure law,
P/T = P'/T'..................... Equation 1
Where P = Initial pressure of helium gas, T = Initial Temperature of helium gas, P' = Final Pressure of helium gas, T' = Final Temperature of helium gas
Make T' the subject of equation 1
T' = P'T/P......................... Equation 2
From the question,
Given: P = 1.5 atm, P' = 2.3 atm, T = 23°C = (23+273)K = 296 K
Substitute these values into equation 2
T' = (2.3×296/1.5)
T' = 680.8/1.5
T' = 453.87 K
T' = 453.87-273
T' = 180.87°C

Answer:
and
Explanation:
All the carbon group atoms, having four valence electrons, form covalent bonds with nonmetal atoms; carbon and silicon cannot lose or gain electrons to form free ions, whereas germanium, tin, and lead do form metallic ions but only with two positive charges
the similarities is that Both carbon and silicon commonly form compounds, easily sharing electrons with other elements. Carbon will make multiple bonds with other carbon molecules by forming single, double and triple covalent bonds. ... Carbon and silicon are often combined, with carbon serving as silicon's backbone.
