It is given that by using track and cart we can record the time and the distance travelled and also the speed of the cart can be recorded. With all this data we can solve questions on the laws of motion.
Like using the first law of motion we can determine the force of gravity acting on the cart that has moved a certain distance and the velocity or the speed of card has already been registered and since time is known putting the values in formula would help us calculate the gravitational pull acting on cart.
The sentence can be completed as follows:
"Electricity is the movement of charges from one atom to another along a conductor."
The movement of the the charges is due to the presence of a potential difference across the conductor, which pushes the charges. More specifically, in normal conductors, the carriers of electricity are the electrons. Therefore we can rewrite the sentence as
"Electricity is the movement of electrons from one atom to another along a conductor."

Answer:
Explanation:
Given:
- volume of liquid content in the can,
- mass of filled can,
- weight of empty can,
<u>So, mass of the empty can:</u>
<u>Hence the mass of liquid(soda):</u>
<u>Therefore the density of liquid soda:</u>
(as density is given as mass per unit volume of the substance)
<u>Specific weight of the liquid soda:</u>
Specific gravity is the density of the substance to the density of water:
where:
density of water
