Which action can humans take to reduce wave erosion?

Physics
1 answer:
mezya [45]2 years ago
3 0

The action that  humans can take to reduce wave erosion is to build breakwaters in the ocean.

<h3>What is erosion?</h3>

The term erosion has to do with the washing away of top soil either by water or by wind. The control of erosion is a very important soil conservation effort.

Hence, the action that  humans can take to reduce wave erosion is to build breakwaters in the ocean.

dimaraw [331]

Answer:

bounce up and down

Explanation:

Buoys are used for two main reasons, one is to let the people on land know of a big incoming wave, while the second reason is to generate electricity. When a big wave is approaching the buoy starts to bounce up and down with the strength of the smalled previous waves and then bounce very strongly up as the bigger wave passes by. This movement is combined with pistons within the buoy in order to conduct electricity.

3) connect two lamps to a power supply in series and current drawn from the power supply is is. connect the same two lamps in pa
notka56 [123]

The current drawn by the series circuit is(R₁ + R₂)/R₁R₂  times the current drawn by the parallel circuit.

Let the resistance of the two lamps are R₁ and R₂.

Then the equivalent resistance in series combination is: R = R₁ + R₂.

And,  the equivalent resistance in parallel combination is:

r = R₁R₂/(R₁ + R₂).

So, if the supply voltage is V,

Then, current drown in series combination; i_s = V/R = V/(R₁ + R₂)

And, current drown in parallel combination; i_p = V/r = V(R₁ + R₂)/R₁R₂

So ,\frac{i_s}{i_p} = [ V/(R₁ + R₂)] /[V(R₁ + R₂)/R₁R₂]

=  (R₁ + R₂)/R₁R₂

Hence, the  ratio of current drawn in series and current drown in parallel is  (R₁ + R₂)/R₁R₂.  So, he current drawn by the series circuit is(R₁ + R₂)/R₁R₂  times the current drawn by the parallel circuit.

State one difference between solar cells and solar heating systems?
seropon [69]
Solar photovoltaic cells, or solar panels, are arrays of silicon cells that can transforms light radiation into electricity. Solar heating system absorbs the heat from the sun and either transform it into electricity through s generator or uses the energy to heat homes and water.
