A block has acceleration a when pulled by a string. If two identical blocks are glued together and pulled with twice the original force, their acceleration will be... ... As a result, if you double both the mass and the force, the acceleration will remain the same.
(C) a

Answer:
Acceleration of two blocks with twice the force will be the same a
Explanation:
Acceleration of a block on Horizontal Surface: When frame is shifting below software of pressure P, then kinetic friction opposes its motion. Let, a is the internet acceleration of the frame, from the determine ma = P – Fk ⇒ a=P−Fkm. Acceleration (a) is the alternate in speed (Δv) over the alternate in time (Δt), represented with the aid of using the equation a = Δv/Δt. This lets in you to degree how rapid speed modifications in meters consistent with 2d squared (m/s^2).
From the Second Law of Newton for an item of mass m , if the pressure F is applied, the acceleration can be
a=F/m
If same blocks are glued together, their mass can be 2m. With the pressure identical to F the acceleration can be
2F/2m =F/m = a
