In my view, correct answer should look like this: Although wave power does not produce pollution, some people may not want to invest in it because it is <span>prone to storm damage and limited to particular areas of the ocean.</span>
The answer is Rh = 135 cm^3 and B = 0.05185 wh/m^2
Explanation:
Resitivity of silicon = 0.1
thickness = 100um
so, I = ma
Required to find out concentration of electron , we know that
Rh = up
By putting in the values,
Rh = 1350 x 0.1
Rh = 135 cm^3
Now consider,
Rh = 1 / Rh.q
= 1 / Rh . q
= 1 / 135 x1.609 x10^-19
= 4.6037 x 10^16 / cm^3
Vh = BIRh / w
B = Vh w/ IRh
B = -70 x10^-6 x 100 x10^-6 / 1x 10^-3 x 135 x 10^-6
B = 0.05185 wh / m^2

Answer:
Decomposers are organisms that break down dead or decaying organisms, they carry out decomposition, a process possible by only certain kingdoms, such as fungi. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. While the terms decomposer and detritivore are often interchangeably used, detritivores ingest and digest dead matter internally, while decomposers directly absorb nutrients through external chemical and biological processes. Thus, invertebrates such as earthworms, woodlice, and sea cucumbers are technically detritivores, not decomposers, since they must ingest nutrients - they are unable to absorb them externally.

Answer:
a
The time it would take the beef to reach a temperature of 0⁰C is t= 662 sec = 11.93 min
b)
The time it would take to heat the beef to uniform temperature of 80⁰C is
t = 365 sec =5.93 min
c
Efficient absorption of Microwave power is in regions of liquid water . Hence if the food or the microwave irradiation is not uniform, the power will be absorbed non-uniformly, resulting in a non-uniform temperature rise. Defrost region will absorb more energy per unit volume than frozen region.if food is of low thermal conductivity, there will be insufficient time for heat conduction to make the temperature more uniform.Use of low power allows more time for conduction to occur.
