Answer
given,
flow rate = p = 660 kg/m³
outer radius = 2.8 cm
P₁ - P₂ = 1.20 k Pa
inlet radius = 1.40 cm
using continuity equation
A₁ v₁ = A₂ v₂
π r₁² v₁ = π r₁² v₂
Applying Bernoulli's equation
v₂ = 1.97 m/s
b) fluid flow rate
Q = A₂ V₂
Q = π (0.014)² x 1.97
Q = 1.21 x 10⁻³ m³/s
Answer:
Explanation:
The motion of a projectile consists of two independent motions:
- A uniform motion along the horizontal direction (constant velocity)
- A uniformly accelerated motion along the vertical direction (constant acceleration)
The time of flight of a projectile is given by
where
is the initial vertical velocity
is the acceleration due to gravity
Here the time of flight is
t = 8 s
So, the initial vertical velocity is:
At the same time, the horizontal distance covered by the projectile is given by
where
is the horizontal velocity, which is constant
t is the time of flight
Here we know that the range of the projectile is 0.3 km, so
d = 0.3 km = 300 m
So the horizontal velocity is
Therefore, we can find the angle of projection of the projectile by using:
A pendulum's time period is the amount of time it takes to complete one oscillation. The pendulum with a length of 3.98 m and a length of 99.4 cm will have a time period of 4 and 1.99 seconds, respectively.
<h3>What is the definition of a simple pendulum?</h3>A simple pendulum is a device with a point mass hanging from fixed support and connected to a light inextensible thread.
The vertical line going through the fixed support represents the mean position of a basic pendulum.
h = vertical distance from the point of suspension
L = length of the simple pendulum
The time period of the simple penduum is given by
For l = 3.98 m
T = 4 second
For l = 99.4 cm = 0.994 m
T = 1.99 second
The time period of the pendulum having 3.98 m and 99.4 cm in length will be 4 and 1.99 seconds respectively.
