Answer:
W = 30.38 N
Explanation:
Given that,
Mass of a rock, m = 3.1 kg
We need to find the weight of the rock on the surface of Earth. Weight of an object is given by :
W = mg
g is the acceleration due to gravity, g = 9.8 m/s²
W = 3.1 kg × 9.8 m/s²
= 30.38 N
So, the weight of the rock on the Earth is 30.38 N.
Answer: The correct answer is A.
Explanation: In a solution, the substance which is in larger proportion is called as a solvent and the substance which is in smaller proportion is called as a solute.
When we mix a powdered Gatorade in the water, the Gatorade is present smaller proportion and hence will be considered as a solute in a solution and water is present in larger proportion and will be considered as solvent in a solution.
Hence, the correct option is A.
