It is an open series circuit and this is why:
its obvious its a series circuit because all the symbols are in a straight rectangle.
its an open circuit because an open circuit has something that doesn't allow the electrons to flow all the way. and the thing blocking the electrons it the switch which is open, (off).
Hope this helped!! sorry its late!!
Answer: 625 grams
Explanation:
14 goes into 56, 4 times.
10,000÷2=5,000 - first half life
5,000÷2=2,500 - second half life
2,500÷2=1,250 - 3rd half life
1,250÷2= 625 - 4th half life
Note: don't type "grams" after 625, just type "625".
The question is incomplete, complete question is:
A fluid occupying 
of volume has a mass of 4 Mg. Calculate its density and specific volume in SI, EE, and BG units.
Explanation:
1) Mass of liquid = m = 4 Mg = 4 × 1,000 kg = 4,000 kg
(1 Mg = 1000 kg)
Volume of the fluid = V =
Density of the fluid = D
Specific volume is the reciprocal of the density :
Specific volume of the fluid = 
2)
Density of the fluid in English Engineering units = D 
1 kg = 2.20462 lb
1 m = 3.280 ft
Specific volume of the fluid :
3)
Density of the fluid in British Gravitational System units = D 
1 kg = 0.06852 slug
1 m = 3.280 ft
Specific volume of the fluid :
The answer is (1) 24. There are 26 protons in nucleus of Fe atom. There is 26 electrons in Fe atom. Fe atom loses 2 electrons and change to Fe2+ ion. So there is 24 electrons in Fe2+ ion.
