An electric clothes dryer that draws 20 amps of current from a 240-volt wall outlet will use 4800 watts of power.
The equation is P(W) = I(A) × V<span>(V)</span>
<span>P(W)= amp x voltage</span>
<span>20 amps x 240 volts = 4800 watts.</span>
Answer:
Yes. Cells have 'cell receptors' that are used to receive messengers like hormones to communicate. Cell receptors have specific shapes that fit the shape of the messenger that they want to receive. Organs like the pancreas send our these messengers to the cells to order them to do different functions.
Answer:
The correct option is C. Building a well between the two wells that goes deeper into the earth would not stop the water from being polluted .
Explanation:
Even if a well was constructed between the wells B and C, it wouldn't have stopped the contamination of the water. As the oil would still be leaking and it would contaminate the wells.
All of the other options can be used to stop the contamination.
Option A suggests building an impermeable membrane that would stop the oil flow. Hence, the water in the wells will not be contaminated.
Option B suggests not using the water from the wells and using an alternate water supply. The alternate water supply wouldn't be contaminated with oil.
Option D suggests chemically purifying the contaminated water. This can be an effective technique to clean the contaminated water.
