I think (1) redox reaction is the correct answer.
Answer:
F' = 3 N
Explanation:
Given that,
Two objects of equal mass have a force of gravity of 6 N between them.
If the mass of one is cut in half and the other stays the same such that,
m₁' = m₁ and m₂' = (m₂/2)
We need to find the new force. The gravitational force between two objects is given by :
We have, F = 6 N
New force,
So, the new force becomes 3 N.
Heat travels from hot to cold in order to balance out the temperature. Thus, the heat transfer goes from the hot water to the finger.
If the water was hot enough, it would transfer too much heat, and the finger would get burned.
The controlled variable is the variable that remains the same throughout the whole experiment. Here, the warm water and the same dishes are the same throughout the whole experiment- so they are the controls
Radioactivity refers to the natural transmutation, whereas transmutation refers to the change of one chemical element into another
