Answer:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
Explanation:
From Physics we remember the definition of work (
), measured in joules, by the following integral equation:
(1)
Where 
is the power, measured in watts.
If the power is stable in time, then the work can be calculated by the following algebraic equation:
(2)
If we know that 
and 
, then the work done by the 35-light bulb is:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
Answer:
Total body water (TBW) will be unchanged because the woman replaced all volume lost in sweat by drinking water. Hematocrit will be increased because of the shift of water from ECF to ICF and the shift of water into the red blood cells (RBCs), which causes their volume to increase.
Explanation:
Aluminum hydroxide is used as an antacid to counteract hyper acidity associated with the gastritis and peptic ulcer disease which includes duodenal ulcer and gastric ulcer and hiatal hernia.
<u>
Oral dosage (oral suspension)
</u>
Adults
Recommended OTC dose of aluminum hydroxide is 10 mL PO 5—6 times per day, after having meals and at bedtime.
Children
Recommended OTC dose of aluminum hydroxide is 5—15 mL PO every 3—6 hours, or 1 and 3 hours after having meals and at bedtime.
Infants
Recommended OTC dose of aluminum hydroxide is 1—2 mL/kg PO per dose and should be given 1—3 hours after having meals and at bedtime.
Answer:
The correct answer is <em>b. Negative</em>
Explanation:
An electrolytic cell is based on a reduction- oxidation reaction which is non spontaneous. That means that the standard cell potencial (Eº) is negative. For this reason, an electrical potential must be applied in order to force the reaction. Conversely, a galvanic cell is based on a spontaneous redox reaction, so the galvanic cell produces electrical energy.
Each mole of a substance contains 6.02 x 10²³ particles
Atoms of Fe = 4.5 x 6.02 x 10²³
= 2.709 x 10²⁹ atoms
