What is the relationship between air pressure and wind velocity
iVinArrow [24]
Air pressure is proportional to the square of the wind velocity.

Wind speed is how fast wind goes and atmospheric pressure is the pressure that the atmosphere pushes on us. The greater the difference in barometric pressure from a high pressure zone to a low pressure zone, the greater the wind velocity will be.

Hope this helped!

A 900 kg car runs into a 70 kg deer at 28 m/s. If the car transfers all of its momentum to the deer, how fast does the deer go f
Alex

Answer:

Mc = 900 Kg

Uc = 28 ms^-1

Md = 70 Kg

Ud = 0

We want Vd

Vc = Vd

This situation is elastic momentum

m _{c}u _{c}+ m _{d}u _{d} = m _{c}v _{c} + m _ dv _{d} \\  (900 \times 28) + (70 \times 0) = (900 \times v _{d} ) + (70 \times v _{d}) \\ 25200 = (900 + 70)v _{d}  \\ 25200 = 970v _{d} \\ v _{d} =  \frac{25200}{970}  \\ v _{d} = 26 \: m {s}^{ - 1}

Distinguish between directly proportional and inversely proportional with an example of each
RideAnS [48]

Consider two variables said to be "inversely proportional" to each other. If all other variables are held constant, the magnitude or absolute value of one inversely proportional variable decreases if the other variable increases, while their product (the constant of proportionality k) is always the same.
