Answer 2

Answer: 6

Step-by-step explanation:

The ability to constantly increase or develop; a force that makes something move faster and faster.

We know that momentum is given by "p'

The formula of p is p=m*v

where m is mass and v is velocity

The dimensional formula of mass is $[M]$

and dimensional formula of velocity is$[LT^{-1}$

Therefore the dimensional formula of momentum will be $[MLT^{-1}]$.....(1)

Now compare with the given dimensional formula in question i.e.

$[M^aL^bT^c]$.....(2)

Put (1)=(2)

$[M^aL^bT^c]=[MLT^{-1}]$
Therefore, a=1, b=1 and c=-1....(3)

Now to find the value of (a+b-4c)...(4)

put the value of a,b, and c from (3) in (4)

therefore, $(a+b-4c)=(1+1-4*(-1))$

Hence,  (a+b-4c)=6
