Answer 1

Thanks for question!!

we know that the dimensions of Length is L.

Option D is correct ✔✔✔

Explanation :-

Dimensions of

${at}^{2}$

Dimensions of acceleration

$a = l {t}^{ - 2}$

Now dimensions of time

$a = l {t}^{ - 2 + 2}$

$a = l$

hence LHS = RHS

option D is correct ans in term of acceleration and time.

Answer 2

Answer:

the dimensions of Length is L.

Option D is correct

Explanation :-

Dimensions of

{at}^{2}at

2

Dimensions of acceleration

a = l {t}^{ - 2}a=lt

−2

Now dimensions of time

a = l {t}^{ - 2 + 2}a=lt

−2+2

a = la=l

hence LHS = RHS

option D is correct ans in term of acceleration and time
