Conduction. Any material that easily allows heat to move through it. Vacuum. A region of space that contains no matter. Solid.
Don't need the mass (23), but only the atomic number (11). The ion has 1 electron stripped, 10 remaining.
the height of the building is H=36 m.
<h3>What is The Law of Gravity?</h3>
According to Newton's law of gravity, every particle of matter in the universe is attracted to every other particle with a force that varies directly as the product of their masses and inversely as their distance from one another.
Properties of Gravity -
- It is a universal attractive force. It is directly proportional to the product of the masses of the two bodies.
- It obey inverse square law.
- It is the weakest force known in nature.
Examples of Gravity -
- The force that holds the gases in the sun.
- The force that causes a ball you throw in the air to come down again.
- The force that causes a car to coast downhill even when you aren't stepping on the gas.
v₀=0 m/s
H₀=0 m
g=10 m/s²
t=7,2 s
H - ?
H = 0 +0 × 7.2 + 10(7.2)²/2
H = 36m

Energy is destroyed because animals are higher levels do not need as much energy. That is option B.
<h3>Energy movement in a food chain</h3>
Food chain is defined as the sequence that shows the feeding relationship between different organisms and how energy flows from the producers to decomposers.
The producers which are the plants traps in energy from the sunlight with the help of their green pigment called the chlorophyll.
The energy continuously flows from the producers to consumers and then to the decomposers.
From the law of conservation of energy, it is neither created nor destroyed.
Therefore energy is destroyed because animals at higher levels do not need as much energy, is not a valid statement.

When we dissolve NaCl in water, the ions are held in a rigid cage of water molecules. It takes less energy to activate these molecules, so the specific heat of the water decreases. The greater concentration of NaCl, the lower the specific heat capacity of the solution.
