If the mass of a
mixer [17]

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 :

F=ma

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.

a=\dfrac{F}{m}

Let a' is the final acceleration,

a'=\dfrac{F}{m'}

m' = 3m

a'=\dfrac{F}{3m}

a'=\dfrac{1}{3}\times \dfrac{F}{m}

a'=\dfrac{1}{3}\times a

So, the final acceleration becomes (1/3) of the initial acceleration. Hence, this is the required solution.

If the cross-sectional area of a wire is decreased while all other factors remain the same, how will the resistance change?
Nataly [62]

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.
