Any fire extinguisher should put out a fire, that is unless the extinguisher is old and faulty.
Because it has a smaller atomic number. Elements are not lined up according to the higher average atomic mass, but rather according to the higher atomic number.
Answer:
Explanation:
The<em> energy of a photon</em>, E, can be calculated with the Planck-Einstein equation:
Where:
- h is Planck's constant 6.626×10⁻³⁴ J.s, and
- f is the frequency of the photon or electromagnetic radiation.
Substituting with your data:
Now multiply by Avogadro's number to obtain the energy of one mole of photons:
Answer:
testosterone, a steroid hormone
molecular oxygen (O₂)
Explanation:
Phospholipid Bi layer is permeable to some molecules and it will allow them to pass through it freely. Molecules which are soluble in water (polar molecules or hydrophillic molecules) are less permeable through phospholipid Bi layer . In given options Molecular Oxygen and Testosterone( steroid Hormone) are permeable through the layer because of its lipid solubility and size of the molecule .
