Answer:
The final acceleration becomes (1/3) of the initial acceleration.
Explanation:
The second law of motion gives the relationship between the net force, mass and the acceleration of an object. It is given by :

m = mass
a = acceleration
According to given condition, if the mass of a sliding block is tripled while a constant net force is applied. We need to find how much does the acceleration decrease.

Let a' is the final acceleration,

m' = 3m



So, the final acceleration becomes (1/3) of the initial acceleration. Hence, this is the required solution.
Answer:
I think it is false. Johann balmer analyzed the spectral lines of hydrogen
The forces cancel out each other because they are equal and opposite. Therefore the net force is 0 and there will be no acceleration
Answer:
A. It will increase
Explanation:
Area of a wire is:
R = ρL/A
where ρ is the resistivity of the wire,
L is the length of the wire,
and A is the cross-sectional area.
If A decreases, while ρ and L stay the same, then R will increase.
