Alarge container contains a large amount of water. a hole is drilled on the wall of the container, at a vertical distance h = 0.54 m below the surface of the water. the water surface drops very slowly and its speed is approximately zero. keep 2 decimal places in all answers. (a) find the speed v (in m/s) at which water squirts out of the hole.

Speed can be found through the application of concepts related to potential energy and kinetic energy, for which you have

Where,

m = mass

v = Velocity

g = Gravitational acceleration

h = Height

Re-arrange to find the velocity we have,

Therefore the speed at which water squirts out of the hole is .3253m/s

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
