Explanation:
Answer:
B. The 55 N cat has less mass than the 110 N dog.
Explanation:
Given;
weight of the cat, W₁ = 55 N
Weight of the dog, W₂ = 110 N
distance between the cat and the dog, d = 2 m
The acceleration due to gravity (g) acting on both animals is the same irrespective of their different positions.
g = 9.8 m/s²
Force of gravity, F = W = mg
where;
m is the mass of the animals
The mass of the cat = m₁ = W₁/g
m₁ = 55/9.8 = 5.6 kg
The mass of the dog = m₂ = W₂/g
m₂ = 110/9.8 = 11.22 kg
Therefore, it can be seen that the mass of the cat is less than the mass of the dog.
The Kyoto Protocol required only developed countries to reduce emissions, while the Paris Agreement recognized that climate change is a shared problem and called on all countries to set emissions targets. So the answer is 4. Combating climate change and holding each other accountable for greenhouse gas emissions.
