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:
The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. The ice cream floats because the buoyant force is greater than the weight of the ice cream.
Explanation:
Answer:
H. pylori uses the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2), where NH3 can act as a buffer to the acidic solution in the stomach.
Explanation:
<em>H. pylori</em> is a bacteria that has the enzyme urease to breakdown urea into ammonia (NH3) & carbon dioxide (CO2). The compound of interest here would be ammonia, or NH3. NH3 is a base, although relatively weak to other stronger bases, which means it has a pH above 7. In the stomach, the pH is acidic, or below 7. By synthesizing ammonia, <em>H. pylori </em>is able to buffer the stomach solution in a manner so that it isn't entirely acidic, but more toward the basic side, thereby allowing for its survival.
Answer:
Increase in eosinophils.
Explanation:
The leukocytes are the white blood cell that plays an important role in the immune system. The white blood cell include eosinophil, basophil, neutrophil and monocytes.
The allergic reactions that are caused by hay fever or asthma is marked by the excess increase in the number of eosinophils in the body. The eosinophils are the first to reach at the site of parasitic infections and protect the body during the allergic reactions.
Thus, the answer is eosinophils.
