Answer ) Sound level equation
The intensity of a sound wave is related to its amplitude squared by the following relationship: I=(Δp)22ρvw I = ( Δ p ) 2 2 ρ v w . Here Δp is the pressure variation or pressure amplitude (half the difference between the maximum and minimum pressure in the sound wave) in units of pascals (Pa) or N/m2.
Yosemite falls has a total height of 73,900 cm it means it heights 739 meters
Answer:
cytoplasm and channel gates
Explanation:
The movement originates from the cytoplasm. This is the fluid medium through which ions are shuttle from one place to another. However, though simple as it might appear to be, the movement requires carrier proteins. The are proteins that facilitate in the movement of the ions. These proteins have specially controlled gates called channel proteins. These are regulated proteins that open and close based on hydrogen ion concentration. These proteins are able to facilitate the movement of ATP molecules.
The matter is a collection or composition of extremely small particles called "Atoms".
<u>Explanation</u>:
- The matter is anything that has mass and which utilizes space by having volume.
- Modern scientists describe the makeup of matter as a collection of tiny substances called atoms.
- Matter can either be in solid, liquid, or gaseous state and even appear in plasma form.
- Matter can neither be created nor be destroyed but only transferred from one form to the other.
- Atoms are composed protons, neutrons and electrons. The protons and neutrons are contained in the nucleus, while the electrons orbit around the nucleus of the atom.
- Protons are positively charged, neutrons are neutral and electrons are negative.
Answer:
13.1 m/s
Explanation:
If we assume that there is not air resistance then the horizontal component of velocity remains constant. That is 1.23 m/s
The vertical component of final velocity can be calculated the following way:
So the final velocity will be the square root of the sum of the squares of the component
v² = 1.23² + 13.0²
v = 13.1 m/s
