Yeah!! It is better to decrease the speed of the vehicle so the ejection of gases would happen in slow manner.... then you can save your gasoline
Answer:
Explanation:
a )
Depth of hole from surface of water d = .50 m - .03 m = .47 m
velocity of efflux v = √ 2gd
v = √ (2 x 9.8 x .47 )
v = 3.03 m /s
b )
Volume flow rate = π R² v where R is radius of hole at the bottom .
= 3.14 x ( .005 ) ² x 3.03 m/s
= 2.378 x 10⁻⁴ m³ /s
c )
Volume of water collected in 60 s
= 2.378 x 10⁻⁴ x 60
= 1.4268 x 10⁻² m³
If height attained in collecting container be h
π R² h = 1.4268 x 10⁻² m³ where R is radius of container
3.14 x ( .1 )² x h = 1.4268 x 10⁻²
h = .4544 m .
Pressure at the bottom of container = hρ g
where h is height of water , ρ is density of water
Pressure = .4544 x 1000 x 9.8 N /m²
= 4453.12 N /m²
Answer:
The value speed is
Explanation:
From the question we are told that
The mass of the ping pong ball is
The radius is
The depth of the ping pong inside the water is
Gnerally the force with which the ball will emerge will from the water is mathematically represented as
Here B is the Buoyant force on the ball which is mathematically represented as
Here is the volume of the ball which is mathematically represented as
=>
=>
is the density of water with value
So
=>
So
=>
=>
Generally force is mathematically represented as
So
=>
Generally from kinematic equation
Here u is the velocity of the ping pong at depth of 0.3 m and the value is zero given that at that point there was no motion
So
=>
The sediment size that would allow water to flow through at the fastest rate are pebbles. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is consequently transported by the action of wind, or ice, and or by the force of gravity acting on the particles. Pebble is a clast of rock with a particle size of 2 to 64 millimeters based on the scale of sedimentology.
