What type of wave is produced when the frequency of a visible light wave is increased
SIZIF [17.4K]

-- If the frequency of a wave is too high for our eyes to detect it ... but not <u>too too</u> high ... we call it an <em>ultraviolet </em>wave.

-- If the wave's frequency is even higher than that, we call it an <em>X-ray</em> wave.

-- If the wave's frequency is even higher than that, we call it a <em>Gamma Ray </em>wave.

An airplane is traveling at 250 m/s in level flight. If the airplane is to make a change in direction, it must travel is a horiz
Nonamiya [84]

Answer:

The radius of curvature of the curved path of the airplane is 23784.356 meters (23.784 kilometers).

Explanation:

We assume that airplane can be represented as a particle. The free body diagram of the vehicle is presented below as attachment, whose variables are:

W - Weight of the airplane, measured in newtons.

F - Lift, measured in newtons.

\theta - Banking angle, measured in sexagesimal degrees.

The equations of equilibrium associated with the airplane are, respectively:

\Sigma F_{r} = F\cdot \sin \theta = m\cdot \frac{v^{2}}{R} (Eq. 1)

\Sigma F_{z} = F\cdot \cos \theta - W = 0 (Eq. 2)

From (Eq. 2):

F = \frac{W}{\cos \theta}

In (Eq. 1):

W\cdot \tan \theta = m\cdot \frac{v^{2}}{R}

By using the definition of weight, we eliminate the mass of the airplane:

g\cdot \tan \theta = \frac{v^{2}}{R}

Where:

g - Gravitational acceleration, measured in meters per square second.

v - Speed, measured in meters per second.

R - Radius of curvature, measured in meters.

Lastly, we clear the radius of curvature with the expression:

R = \frac{v^{2}}{g\cdot \tan \theta}

If we know that v = 250\,\frac{m}{s}, g = 9.807\,\frac{m}{s^{2}} and \theta = 15^{\circ}, the radius of curvature is:

R = \frac{\left(250\,\frac{m}{s} \right)^{2}}{\left(9.807\,\frac{m}{s^{2}} \right)\cdot \tan 15^{\circ}}

R = 23784.356\,m

The radius of curvature of the curved path of the airplane is 23784.356 meters (23.784 kilometers).

Galileo challenged the idea that objects in the heavens were perfect by ________.
DENIUS [597]

Answer:

d. observing sunspots on the Sun and mountains on the Moon

Explanation:

Galileo was an Italian Physicist and Astronomer and is regarded as the father of modern Physics.

It was previously believed that the objects in the heavens such as the sun, moon and stars were perfect and rough till he observed sunspots on the sun and mountains on the moon which indicates the surface of the moon is rough with mountains and craters.
