Question

can anyone pls give the solution for this question with crct explanation? ​

Answer 1

Answer:

4.2a ¹3-²y² new unit.

Explanation:

We know that the dimensional formula of heat energy is

[M¹ L² T-2]

It is given that,

1cal = 4.2 J

In SI system, M₁ = 1 kg, L₁ = 1 m, T₁=1 s

In new system of units,

M₂ = akg, L₂ = 3m, T₂ = ys

We know,

M₁ a LI b T₁ C 112 = 1լ

n₂ = 4.2 1 kg akg -2 m 3m

-1 = 4.2a ¹8-²²

1cal = 4.2a ¹8-²² new unit.
