The second one is correct. Alleles on homologous chromosomes determine traits
they look correct I think I am right :)
Answer : Gaseous water molecules condense when they cooled. Liquid water molecules evaporate when they heated.
Explanation :
Condensation : It is a process in which a phase changes from gaseous state to liquid state. This process occurs when the water molecules in the air cool down and they join together to form liquid water.
Evaporation : It is a process in which a phase changes from liquid state to gaseous state. This process occurs when the water is heated, the molecules in the water move and vibrate quickly that they escape into the atmosphere as water vapor.
You need the heat of fusion of ice to solve this problem. <span>the heat of fusion of water = 334 J/g </span><span>
the formula to solve for heat is </span>q = m·ΔH<span>f</span>
just plug the values
q= (50.0 g) (334 j/g)= 16700 joules or 16.7 Kj
Answer:
The correct answer is:
An electron will be emitted in the second experiment, but it cannot be determined whether it will reach the second plate.
Explanation:
In fact, violet has higher frequency than green light. This means that photons on violet carry more energy than photons of green light (remember that the energy of a photon is proportional to it's frequency:
, so when they hit the surface of the metal, more energy is transferred to the electrons. The electron was already emitted with green light, so it must be emitted with also violet light, given the more energy transferred.
