2. A small car has a mass of 890 kg. What is its weight? (Hint: remember the definition of weight).

8722N

Explanation:

the formula of converting mass to weight is as follows: mass (in kg) × acceleration (in m/s) due to gravity = weight (in newtons)

on earth, the acceleration due to gravity is 9.8 m/s².

therefore, 890kg × 9.8 m/s² = 8722N

i hope this helps! :D

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
