A conductor is something which allows electricity to pass through it
an example is a coin
An insulator is something which cannot allow electricity to pass through it
an example is plastic (or plastic cotton reel, plastic container ect.)
Static electricity is when you rub two things together to create static
I'm not sure if i helped on the last question but i am definitely sure of the first ones
Answer:
The amount of energy that would be released is equal to 4182 Joules.
Explanation:
Total amount of coke = 2 kg = 2000 g
1 calorie per gram is equal to 4.184 Joules of energy
4.184 J/gC*2000g = 8368 J
1 food calorie is roughly equal to 4186 J
8368 - 4186
Therefore, the amount of energy that would be released is equal to 4182 Joules.
Answer:
12500(kg*m/s)
Explanation:
F=ma=mv/t=p/t
p=F*t=500N*25 s=12500(kg*m/s)

Answer:
area = 5733.33 cm²
length = 5.47 ×
cm
Explanation:
Given data
density = 19.32 g/cm³
mass = 33.16 g
thickness = 3.000 µm = 3 ×
cm
radius r = 1.000 µm = 1 × cm
to find out
area of the leaf and length of the fiber
solution
we know volume formula that is
volume = mass / density
volume = 33.16 / 19.32
volume = 1.72 cm³
we know that volume = thickness × area
so area
area = volume / thickness
area = 1.72 / 3 ×
area = 5733.33 cm²
and
we know volume = πr²L
so L = volume / πr²
length = 1.72 / π(1×)²
length = 5.47 × cm
