Final answer:
The weight of 1 kg of water is 9.8 N.
Step-by-step explanation:
The weight of an object can be calculated by multiplying the mass of the object by the acceleration due to gravity. The weight of 1 kg of water can be calculated as:
The weight of an object is calculated by multiplying its mass by the acceleration due to gravity, which is approximately 9.8 m/s2. Therefore, the weight W of 1 kg of water would be:
Weight = mass x acceleration due to gravity
The standard acceleration due to gravity is approximately 9.8 m/s^2. Therefore, the weight of 1 kg of water would be:
Weight = 1 kg x 9.8 m/s^2 = 9.8 N
So the correct answer is a) 9.8 N.
