1. The box like figure in the given image is the [BATTERY SOURCE] from where the current drawn into the circuit.
2. A string connecting positive terminal of battery to the bulb is an [ELECTRIC WIRE] through which current flows in the circuit.
3. A bubble like object in the circuit is a [BULB] which lights up when current moves through the circuit.
4. A component connected to the negative terminal of batter source is a [SWITCH].
The answer are uppercase.

Answer:- The right choice is A.
.
Solution:- Latent heat of fusion means the heat required to melt the solid at constant temperature means there is no change in temperature only the solid changes to liquid. So, it is a solid to liquid phase change.

where q is the heat required to convert solid to liquid, m is the mass and
is the latent heat of fusion.
From given info, 550 kJ that is 550000 J of heat is required to melt 14 kg of solid at 262K temperature. Let's rearrange the equation for latent heat of fusion and plug in the values in it.


= 
If we round this value to two sig figs and write in scientific notations then it becomes
.
So, the right choice is A.

Answer:
The answer is 5 mol
Explanation:
Number Of Moles = Mass Of Substance ÷ Mass Of One Mole
Mass of NaOH = Molar Mass of Sodium + Oxygen + Hydrogen
23 + 16 + 1
40 g/mol
Number of Mole = 200/40 = 5 mol
Thus, The number of Moles in 200 grams of Sodium hydroxide is 5 mol
