Answer:
The given blank can be filled with direct.
Explanation:
A battery refers to a chemical apparatus that is used to store electrical energy. A battery generates a direct current that is a current, which flows in only one direction. DC means direct current and it should exhibit fixed terminals, that is, negative and positive terminals, which cannot be altered.
As the batteries have fixed content, they possess fixed terminals, thus, they can store only direct current. Thus, the batteries produce direct current and produce a voltage in only one direction, and they exhibit a polarity of negative and positive.
Answer:
It is called the superior sagittal sinus.
Explanation:
The superior sagittal sinus which is often called the superior longitudinal sinus) is situated in the human head. It is an unpaired region in the human head around the attached margin of the falx cerebri. It main function is to ensure that blood is removed from the lateral parts of the anterior cerebral hemispheres and transferred to the confluence of sinuses. It also has a triangular cross sectional area and with a left/right lateral angles at its junctions. Therefore, The right answer is the the superior sagittal sinus.
Answer:
22 kph
Explanation:
You simply divide the distance and the time. 66/3 = 22.
The gram formula mass of Na2SO4 is 23*2+32+16*4=142. And the mass for sodium is 23*2=46. So the percent by mass is 46/142*100%=32.4%.
Molarity is defined as the number of moles of solute in 1 L of solution
number of NaOH moles present - 0.20 mol
volume of solution - 150 mL
since molarity is taken as number moles of solute in 1000 mL
if 150 mL contains - 0.20 mol
then 1000 mL should contain - 0.20 / 150 x 1000 = 1.33 mol
therefore molarity is 1.33 M
