<u>Tangent and Angular Velocities</u>
In the uniform circular motion, an object describes the same angles in the same times. If is the angle formed by the trajectory of the object in a time t, then its angular velocity is
if is expressed in radians and t in seconds the units of w is rad/s. If the circular motion is uniform, the object forms an angle
in 2t, or
in 3t, etc. Thus the angular velocity is constant.
The magnitude of the tangent or linear velocity is computed as the ratio between the arc length and the time taken to travel that distance:
Replacing the formula for w, we have
Answer:
The correct answer to the following question will be "41.87 m".
Explanation:
The given values are:
The speed of trooper =
The velocity of red car =
Now,
A red car goes as far as possible until the speed or velocity of the troops is the same as that of of the red car at
(∵
)
then,
The distance covered by trooper,
The distance covered by red car,
=
=
Maximum distance =
=
Answer:
Because the wavelengths of macroscopic objects are too short for them to be detectable.
Explanation:
Wavelength of an object is given by de Broglie wavelength as:
Where, 'h' is Planck's constant, 'm' is mass of object and 'v' is its velocity.
So, for macroscopic objects, the mass is very large compared to microscopic objects. As we can observe from the above formula, there is an inverse relationship between the mass and wavelength of the object.
So, for vary larger masses, the wavelength would be too short and one will find it undetectable. Therefore, we don't observe wave properties in macroscopic objects.
