I think the answer is B but not too sure.
Well since I don't have access to a high vacuum pump or good glassblowing equipment I would say wiring would be cotton thread and the coating would be carbon, ideally with a high vaccum pump and glassblowing equipment I'd say platinum wire with a resistive coating to prevent the platinum from getting to hot but would keep it incandescent for a very long time.
Answer:
A quasar is an extremely bright, distant object visible to radio telescopes.
Answer:
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

Explanation:
The new volume of water = 25 ml
The old volume of water = 15 ml
The difference = 25 - 15 but what are the units?
Since the question asks for force, the units must start out as 10 mL
In water 1 mL has a mass of 1 gram, so the answer is 10 grams.
Grams are units of mass, not weight. You should convert this into newtons.
10 grams = 1/1000 = 0.01 kg
1 kg has a weight of 9.81 Newtons
0.01 kg has a weight 0.081 Newtons
If you have never seen a Newton before, then the answer is 10 grams
