Explanation:
Motion is when an object changes position over time. The object in motion is usually in front of a reference point-an object that appears to stay in one place. The rate at which an object moves is called speed. Speed depends on both time and distance. The velocity of an object is how fast it is going in one direction
How do you know if an object has changed position?
changes position requires a point of reference. An object changes position if it moves relative to a reference point. To visualize this, picture yourself competing in a 100-m dash. You begin just behind the start line
Answer:
The ratio is 
Explanation:
Generally the Moment of inertia of a spherical object (shell) is mathematically represented as

Where m is the mass of the spherical object
and r is the radius
Now the the rotational kinetic energy can be mathematically represented as

Where
is the angular velocity which is mathematically represented as

=> ![w^2 = [\frac{v}{r}] ^2](https://tex.z-dn.net/?f=w%5E2%20%20%3D%20%20%20%5B%5Cfrac%7Bv%7D%7Br%7D%5D%20%5E2)
So
![RE = \frac{1}{2}* [\frac{2}{3} *mr^2] * [\frac{v}{r} ]^2](https://tex.z-dn.net/?f=RE%20%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%20%20%5B%5Cfrac%7B2%7D%7B3%7D%20%2Amr%5E2%5D%20%2A%20%20%20%5B%5Cfrac%7Bv%7D%7Br%7D%20%5D%5E2)

Generally the transnational kinetic energy of this motion is mathematically represented as

So


As per kinematics equation we are given that

now we are given that
a = 2.55 m/s^2


now we need to find x
from above equation we have



so it will cover a distance of 93.2 m
I think it's C, longer wave length.
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
