Question

Physics Headache™ 1 : 20 points , 5 mins . Question 6

Answer 1

P = (a-t²)/bx

Pressure = Force/Area
P = m×a/area
P = M×(L/T²) × (1/L²)
P = M¹ L¯¹ T ¯²

M¹ L¯¹ T¯² = (a- T²)/bL¹
a - T² = b M¹ Lº T¯²

a/b = M¹ Lº T¯²

========================

Answer 2

HELLO FRIENDS ,

We know that 
Pressure = Force/area 
(For dimension of pressure put value of dimensions of force and area)
Pressure = m. a / a      (force = m.a)
               = [M][L]-1[T]-2

NOW PUT it in main equation 

M¹ L-¹ T-² = (a- T²)/bL¹
a - T² = b M¹ T-²
a/b =M¹ T-²
     OR
a/b = M¹ Lº T-²

so option B) is correct
