The difference in height between the ground floor and the third floor is
<h3>What is gauge pressure?</h3>
The pressure measured by the pressure gauge is called the gauge pressure.
Given is the the pressure in a water pipe in the ground floor of a building is 4×10⁵ Pa and three floors up is 2×10⁵ Pa. Density of water ρ = 1×10³ kg/m³
From the Bernoulli's theorem,
ΔPg = ρgΔh
( 4×10⁵ - 2×10⁵) = 1000 x 9.81 x Δh
Δh = 20.4 m
Thus, the difference in height is 20.4 m

Answer:
8.136×10⁻⁵ J
Explanation:
Applying,
Q = Cv................ Equation 1
Where Q = Charge on the capacitor, v = voltage of the battery, C = capacitance of the capacitor.
From the question,
Given: C = 6.78μF = 6.78×10⁻⁶ F, v = 12 V
Substitute these values into equation 1
Q = (6.78×10⁻⁶ )(12)
Q = 8.136×10⁻⁵ J
Hence the charge on the capacitor is 8.136×10⁻⁵ J
choose the first option ...........
Objects dropped straight or thrown horizontally from the same height
change their vertical velocity at the same rate, and fall through equal
vertical distances in equal time intervals.
The statement is false.
