Answer 1

मुझे मुझे माफ कर दो इसका आंसर मुझे नहीं पता है

Answer 2

we are given that E=b-x2/at

due to principal of homogeneity b=E i.e [M L2 T-2]

similarly x2/at= E i.e [M L2 T-2]

so at= x2/[M L2 T-2]

at=[L2]/[M L2 T-2]

at=[M-1L0T2]

a=[M-1 T2]/[T]

a= [M-1 T1]

so a*b =[M-1T1]*[M L2 T-2]

a*b= [L2 T-1]
