When two air masses with different characteristics meet what happens

Physics

lyudmila [28]3 years ago
3 0

If the boundary between the cold and warm air masses doesn't move, it is called a stationary front. The boundary where a cold air mass meets a cool air mass under a warm air mass is called an occluded front. At a front, the weather is usually unsettled and stormy, and precipitation is common.

A pitched ball is hit by a batter at a 47◦ angle. It just clears the outfield fence, 98 m away. The acceleration of gravity is 9
musickatia [10]

Answer:u=31.02 m/s

Explanation:

Given

launch angle of ball \theta =47^{\circ}

Range of ball R=98 m

considering ball to be a Projectile

Range of Projectile is given by

R=\frac{u^2\sin 2\theta }{g}

Where u=initial\ Velocity

\theta =launch\ angle

g=acceleration\ due\ to\ gravity

98=\frac{u^2\sin 2(47)}{9.8}

98\times 9.8=u^2\sin (94)

u^2=\frac{960.4}{sin (94)}

u^2=962.74

u=31.02 m/s

xenn [34]

Answer:

C. reflects one or more visible light frequencies.

Explanation:

The color that we see is the color that is deflected from the RGBHSB.etc. This means that the light has all the colors within, and the object it hits absorbs all but one color, in which it deflects for our eyes to see.

What is the frequency of radiation whose wavelength is 11.5 a0 ?
irakobra [83]

Answer:

The frequency of radiation is 2.61 \times 10^{17} s^{-1}

Explanation:

Given:

Wavelength \lambda = 11.5 \times 10^{-10} m

Speed of light c = 3 \times 10^{8} \frac{m}{s}

For finding the frequency of radiation,

  c = f \lambda

  f = \frac{c}{\lambda}

  f = \frac{3 \times 10^{8} }{11.5 \times 10^{-10} }

  f = 2.61 \times 10^{17} s^{-1}

Therefore, the frequency of radiation is 2.61 \times 10^{17} s^{-1}
