The mass of this much chain is 0.22 grams for 7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car.
<h3>What are weight and mass?</h3>
Mass is the amount of the substance and object and the weight is the gravitational force required to act upon the particular mass of the substance.
To calculate the mass of car divide the wight to the gravity value 9.8 meter per second.
mass = weight / gravity
substituting the value,
mass = 2.16 / 9.8
mass = 0.22 grams
Therefore,7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car the mass will be 0.22 grams.

Answer:
The volume will be 2600 L.
Explanation:
Initial temperature (
) = 25°C = (25 + 273) K = 298K
Final temperature (
) = 54°C = (54 + 273) K = 327 K
By using the combined gas law equation,
= 
or,
= 
or, 3060 × 327 = 380 × 
or,
≈ 2600 L
Hence the volume of the balloon will be about 2600 L.
It is the 3rd option. Theories must be substantiated by a large amount of evidence and previous research
Gravitational potential energy = mass x g x height
(The g is measured in N/kg and is usually 9.8 or 10)
