Answer:
Photons.
Explanation:
Einstein explained the photoelectric effect by proposing that light is transmitted, not in the form of continuous waves, but in the form of many tiny, discrete packets of energy called photons. Photons are massless and chargeless particle. The energy of a photon is given by :
f is the frequency of photon.
The answer would be dissolved salt. Its the presence of saltwater in marine and the absence of it in freshwater that makes the big difference.
Answer:
a. True
Explanation:
This statement is true, and incredibly important. Every material used in construction has a breaking point and a deformation point. A breaking point is the amount of stress or weight material can handle before it completely gives out and breaks while the deformation point is the point in which it begins to bend or change its shape. Therefore, it is incredibly important to know both this information and the amount of force that will be exerted onto the materials. Mainly because if the amount of force exceeds these points it will cause the material to deform/break which can cause the entire structure to collapse and either injure or kill many people.
