How exactly do you find the intercept based on a simple pendulum graph. we were asked to plot log T against Log L and find the gradient and the acceleration due to gravity (g) the formula for g is 4pi²/antilog c
and were supposed to find c first (from y=mx+c)
and our only hint is that y is in the y axis (log T axis

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
