What happens to speed when wavelength decreases

1 answer:

6 0

Speed = wavelength × frequency

giving that frequency is 0, wavelength and speed are directionally proportional. wavelength decrease = speed decrease

What is the rotational inertia of an object that rolls without slipping down a 2.00-m-high incline starting from rest, and has a

krek1111 [17]

We will apply the concepts of energy conservation to solve the problem. We know that gravitational potential energy is equivalent to the sum of translational kinetic energy and rotational kinetic energy. Additionally, the relation of the angular velocity with the tangential velocity will be determined to eliminate the angular term and obtain the expression of the Inertia in terms of the data given, therefore, we know that

$PE_{g} = KE_{trans} +KE_{rot}$

$mgh = \frac{1}{2} mv^2+\frac{1}{2}I\omega^2$

The angular velocity in terms of tangential velocity and radius is defined as,

$\omega = \frac{v}{R}$

Replacing,

$mgh = \frac{1}{2} mv^2+\frac{1}{2} I(\frac{v}{R})^2$

Multiplying by R^2,

$gh(mR^2) = \frac{v^2}{2} (mR^2)+\frac{v^2}{2}I$

$\frac{v^2}{2}I = (gh-\frac{v^2}{2})mR^2$

$I = (\frac{2gh}{v^2}-1)mR^2$

Replacing with our values we have,

$I = (\frac{2(9.8)(2)}{6^2}-1)mR^2$

$I = 0.089mR^2$

Which three workers uses technologies that apply the Doppler effect

ladessa [460]

Answer:

The technology was also widely employed in fighter aircraft during the 1960s. It is also used in air traffic control systems to pick out aircraft from clutter. Pulse-Doppler RADAR is also the basis of synthetic aperture RADAR that is commonly used in RADAR astronomy, remote sensing, and mapping.
