A clay plate has a volume of 30.0cubic centimeters and a mass of 59.1grams. Calculate its density.
Nataly_w [17]

The density of the clay plate is  1970 kg m⁻³

the problem we are dealing with is related to density, which is the mass of a unit volume of a material substance. The formula for calculating density is d = M/V, where d is density, M is mass, and V is volume. Since we are provided with the volume of the clay plate which is 30.0cubic centimeters and the mass of the plate which is 59.1grams

so,V= 30 cm⁻³=3x 10-5 m and  M=  59.1grams= 0.0591 kg

Therefore, the density of the plate is:  M/V

=>d = 1970 kg m⁻³

Where do electrons get their energy in photosystem I?
tino4ka555 [31]
That would be B. From energy in photons.

Photons(from sunlight) give energy to electrons and “excite” them(sending them to a higher energy level). Electrons can then release this energy and excite other electrons in other chlorophyll molecules.
