8 0

Answer:

pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

Calculating pressure

To calculate pressure, you need to know two things:

Pressure is calculated using this equation:

pressure = force ÷ area.

I NEED HELP The measure of how resistant a solid is to shape change when a force is applied.
enyata [817]

<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>

28. Which statement best explains why cellular respiration in plants and
bazaltina [42]

Answer: Photosynthesis provides the materials that fuel cellular respiration.

Explanation:

Photosynthesis, the process through which green plants convert light to chemical energy. The energy that is gotten from sunlight by green plants, some protistans, and bacteria is used to produce sugar which is then converted to ATP by cellular respiration which is regarded to as the fuel that living things use.

Therefore, the statement that best explains why cellular respiration in plants and other organisms is dependent on photosynthesis is that photosynthesis provides the materials that fuel cellular respiration.
