Answer:
Gravitational energy and thermal energy
Explanation:
A water cycle is a product of gravitational energy from the earth and thermal energy from the sun.
A water cycle is driven around with the help of hydroelectric energy. Now hydroelectric energy is a product of potential energy that is converted into kinetic energy, with the help of gravitational energy, which again is also acquired from thermal energy from the sun.
Therefore, the correct answer is gravitational energy and thermal energy.
Answer:
the modals of arrangement for first periodic table was. increasing atomic mass and grouping together of elements having similar properties
Answer: Metals are shiny and lustrous with a high density. They have very high melting and boiling points because metallic bonding is very strong, so the atoms are reluctant to break apart into a liquid or gas.

Answer:
Mass of carbon = 109.1 g
Explanation:
Given data:
Mass of carbondioxide = 400 g
Mass of carbon = ?
Solution:
Molar mass of carbon = 12 g/mol
Molar mass of CO₂ = 44 g/mol
Mass of carbon in 400g of CO₂:
Mass of carbon = 12 g/mol/44 g/mol × 400 g
Mass of carbon = 109.1 g
