What is the most useful meteorological measurement for forecasting freezing precipitation?
scoray [572]

The most useful meteorological measurement for forecasting freezing precipitation is b. radiosonde soundings

<h3>Radiosonde </h3>

At high altitudes, radiosondes are battery-powered telemetry sensor bundles that detect altitude, pressure, temperature, relative humidity, wind (both speed and direction), and cosmic ray measurements. They are commonly taken into the atmosphere by weather balloons.

Rawindsonde is an acronym for radar wind sonde, a type of radiosonde that tracks its position as it rises through the sky to provide wind speed and direction. Another type of radiosonde is one that falls to the ground after being released from an aircraft, as opposed to being carried by weather balloons. The term "dropsondes" is used to describe this group of radiosondes. The majority of operational atmospheric data assimilation methods depend heavily on radiosondes.

Suppose all the people of the Earth go to the North Pole and, on a signal, all jump straight up. Estimate the recoil speed of th
Makovka662 [10]

Explanation:

It is known that relation between velocity and height is as follows.

              v = \sqrt{2gh}

where,     g = acceleration due to gravity = 9.8 m/s^{2}

                h = height = 0.2 m

Therefore, velocity is calculated as follows.

            v = \sqrt{2gh}

               = \sqrt{2 \times 9.8 \times 0.2}

               = 3.92 m/s

Also,

      m_{people}v_{people} = m_{earth}v_{earth}

    v_{earth} = \frac{m_{people}v_{people}}{m_{earth}}

Putting the given values into the above formula as follows.

     v_{earth} = \frac{m_{people}v_{people}}{m_{earth}}

                = \frac{6 \times 10^{9} \times 74 kg/person}{6 \times 10^{24} kg}

                = \frac{444 \times 10^{9}}{6 \times 10^{24}}

                = 74 \times 10^{-15} m/s

or,             = 7.4 \times 10^{-14} m/s

Thus, we can conclude that recoil speed of the Earth is 7.4 \times 10^{-14} m/s.

I need answers for this help me​
kipiarov [429]

Answer:

Explanation:

Initial momentum

4.0(9) + 2.0(-9) = 18 kg•m/s

final momentum

4.0(-3) + 2.0(15) = 18 kg•m/s

Initial kinetic energy

½4.0(9²) + ½2.0(-9²) = 243 J

final kinetic energy

½4.0(-3²) + ½2.0(15²) = 243 J
