Using two billiard balls, in 3-4 sentences, design an experiment to demonstrate the law of conservation of momentum.
1 answer:
Answer:
In the explanation
Explanation:
<u>Experiment</u>:
Consider two billiard balls of masses ‘m₁’ and ‘m₂’, moving with velocities ‘u₁’ and ‘u₂’, respectively, such that u₁ is greater than u₂. After some time, these balls collide with each other and their velocities become ‘v₁’ and ‘v₂’, respectively.
<u>Observation</u>:
The masses of balls should be measured and their initial and final velocities should be measured.
<u>Result</u>:
In order to prove law of conservation of moment following equation must be satisfied by observed values:

Answer:
pressure of the water = 3.3 × pa
Explanation:
given data
velocity v1 = 1.5 m/s
pressure P = 400,000 Pa
inside radius r1 = 1.00 cm
pipe radius r2 = 0.5 cm
h1 = 0 (datum at inlet)
h2 = 5.0 m (datum at inlet)
density of water ρ = 1000 kg/m³
to find out
pressure of the water
solution
we consider here flow speed in bathroom that is = v2 and Pressure in bathroom is = P2
here we will use both continuity and Bernoulli equations
because here we have more than one unknown so that
v1 × A1 = v2 × A2 × P1 + ρ g h1 + (0.5)ρ v1² = P2 + ρ g h2 + (0.5) ρ v2²
now we use here first continuity equation for get v2
v2 =
v2 =
v2 = 6 m/s
and now we use here bernoulli eqution for find here p2 that is
P2 = P1 - 0.5× ρ ×(v2² - v1²) - ρ g (h2- h1 )
P2 = 400000 - 0.5× 1000 ×(6² - 1.5²) - 1000 × 9.81 × (5-0 )
P2 = 3.3 × pa
Explanation:
Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.
So by using the equation of diffraction,
dsinA = nL
SinA is a geometric component it can be written as,
∵ x is the distance from screen.
∵ y is the half of the width of central maximum.
now by putting the values in mm,
d = 2.15× mm
