!ND he falls down or whatta is this a riddle or a question we can't help you if you are not clear gosh people ...
Answer:
distance - meters
speed - meters/seconds
time - seconds
velocity - meters/seconds
acceleration - meters/seconds²
Answer:
18.62 m/s
Explanation:
Given that:
A liquid with a density of 900 kg/m 3 is stored in a pressurized, closed storage tank.
Diameter of the tank = 10 m
The absolute pressure in the tank above the liquid is 200 kPa = 200, 000 Pa
At pressure of 200 kPa ; the final velocity = 0
Atmospheric pressure at 5cm = 101325 Pa
We are to calculate the initial velocity of a fluid jet when a 5cm diameter orifice is opened at point A?
By using Bernoulli's theorem between the shaded portion in the diagram;
we have:




where;
Pa = atmospheric pressure = 101325 Pa
= density of liquid = 900 kg/m³
= initial velocity = ???
g = 9.8 m/s²
= height of the hole from the buttom
= height of the liquid surface from the button


Thus, the initial velocity of the fluid jet = 18.62 m/s
Answer:
The Height of a pyramid is 4r.

Answer:
The value is
Explanation:
Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as

substituting 1.05 m/s for
and 2.75 m/s for 
So

=>
Generally the distance by which the person is ahead of you is mathematically represented as

substituting 18.5 s for

=>
