The dimensions of magnetic flux are?

The dimension formula of torque is 

A physical quantity $$P$$ is given by the relation, $$P={P}_{0}{e}^{(-\alpha {t}^{2})}$$. If $$t$$ denotes the time, the dimensions of constant $$\alpha$$ are

if $$L=2.331 cm$$, $$B = 2.1 cm$$, then L+B=

A balloon of mass $$1$$ g has $$100$$ g of water in it. If it is completely immersed in water, its mass will be

If mass (M), velocity (V) and time (T) are taken as fundamental units, then the dimensions of force (F) are 

While measuring $$g$$ using simple pendulum method $$\%$$ error in measurement of $$\ell$$ is $$\pm\ 2\%$$ and in measurement time is $$\pm\ 1\%$$ then relative error in $$g$$ is: 

Find the dimension of $$\dfrac {G}{4\pi \epsilon_{0}}$$, where $$G$$ is universal gravitation constant and $$\epsilon_{0}$$ is permittivity

The period of osciflation of a simple pendulum in the recorded as $$2.63 \,sec, 2.42 \,sec, 2.42 \,sec, 2.71 \,sec$$ and $$2.80 \,sec$$ respectively. The average absolute error is

$$X = 3YZ^{2}$$ find dimension of $$Y$$ in $$(MKSA)$$ system, if $$X$$ and $$Z$$ are the dimension of capacity and magnetic field respectively.
