The energy goes from electric energy and gets converted into thermal energy.
Answer:
4.988kW
Explanation:
According to the question, energy E extracted from the ocean breaker is directly proportional to the intensity I. It can be expressed mathematically as E ∝ I
E = kI where k is the constant of proportionality.
From the formula; k = E/I
This shows that increase in energy extracted will lead to increase in its intensity and vice versa.
If the device produces 10.0 kW of power on a day when the breakers are 1.20 m high
E = 10kW and I = 1.20m
k = 10/1.20
k = 8.33kW/m
To know how much energy E that will be produced when they are 0.600 m high, we will use the same formula
k = E/I where;
k = 8.33kW/m
I = 0.600m
E = kI
E = 8.33 × 0.6
E = 4.998kW
The device will produce energy of 4.998kW when they are 0.600m high.
B. dam construction
Explanation:
Dam construction is one man made feature that would likely lead to sand loss on a regardless of active or passive margin setting of the coast line.
We must understand that sand loss is the periodic remove of sand from the beach.
Naturally, crashing waves have the capability at high tides to erode sand away. At other times, the sands are returned.
Dam construction is one artificial way sand can be lost on a beach.
- Dam construction is a civil work
- It is an earth moving process because dams must be built on a stable and structurally secured setting.
- In that regard, if a dam is to be cited close to a beach, more of the sand in a beach will have to go.
- If the sands are left, they can easily be blown into the constructed dam. This is huge problem most civil engineers will not want to address.
