Fluorine is the sample which is shiny but does not conduct heat and electricity through it. The flow of electricity requires the flow of electrons or charged particles. Thus, the correct option is A.
What are conductors?
A conductor is a substance, chemical element, or a material which allows electricity and heat to flow through it. In a conductor, the electrical charge carriers which are usually electrons or positive and negative ions, move easily from one atom to another atom when a particular amount of voltage is applied.
Fluorine is a shiny element however it does not conduct heat and electricity through it. It is the most electronegative atom and is very reactive in nature. It only gains electrons and does not lose them. And because of this property of fluorine, it restricts the movement of electrons through it and fails to conduct electricity.
Therefore, the correct option is A.

2. s/g
Explanation:
1. Determination of the mass of gasoline
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Mathematically, the density of a substance can be expressed as:
Density = mass / volume
With the above formula, we can obtain the mass of the gasoline as follow:
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
Density = mass / volume
0.7 = Mass of gasoline / 15
Cross multiply
Mass of gasoline = 0.7 × 15
Mass of gasoline = 10.5 Kg
2. Density has various units some are listed below:
I. Kilogram per litre (Kg/L)
II. Kilogram per cubic metre (Kg/m³)
III. Milligram per millilitre (mg/mL)
IV. Gram per millilitre (g/mL)
V. Gram per cubic centimetre (g/cm³)
Considering the options given in the question above, it is evident that second per gram (s/g) is not a unit of density because density is mass per unit volume.

Calculate the running costs of a filament lamp with a 60 W bulb and a CFL lamp with a 15 W bulb for 15 hours.
1 kWh costs 10p.
cost = power (kW) × time (hours) × price (per kWh)
Answer:
the cost of running the bulbs is 11.25p
Explanation:
Given;
cost of running 1 kwh = 10 p
power of filament bulb, P = 60 W
power of the CFL bulb, P = 15 W
time of power consumption, t = 15 hours
Total Energy consumed;
E = (60W + 15W) x 15 hours
E = (75)(15)
E = 1125 Wh
E = 1.125 kWh
Cost of 1.125 kWh = 1.125 x 10p
= 11.25p
Therefore, the cost of running the bulbs is 11.25p

A train moves at 300 km/h. How far will it go in 5 hours?
Answer:
1,500 km
Explanation:
300 km/h
300 kilometers PER HOUR
So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.
300 * 5 = 1,500
The train moves at 1,500 km in 5 hours.

A bicyclist steadily speeds up from rest to 11.0m/s during a 5.50s time interval. Determine all unknowns and answer the following questions. What is the magnitude of the bicyclist's acceleration? How far did the bicyclist travel during this time?
Explanation:
acceleration is 2 m/s^2
v-u/t
distance travelled is 30.25 meter
(v^2-u^2)/2a
11*11/2*2
121/4
30.25 m
The acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.
We have a bicyclist.
We have to calculate the acceleration and the total distance travelled by the bicyclist.
State the three equations of motion.The three equations of motion are -
v = u + at
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
v² - u² = 2aS
According to the question -
u = 0 m/s
v = 11 m/s
t = 5.5 s
Therefore -
For acceleration -
v = u + at
On solving -
11 = 0 + 5.5 a
5.5a = 11
a = 11 / 5.5 = 2 m/s²
For total distance covered -
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
On solving -
S = 0 + 0.5 x 2 x 5.5 x 5.5 = 30.25 meters.
Hence, the acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.
