Answer:
precipitation is the answer..
Explanation:
precipitation is any product of the condensation of atmospheric water vapor that falls under gravitational pull from clouds. The main forms of precipitation include drizzling, rain, sleet, snow, ice pellets, graupel and hail.
Answer: observed frequency (f') = 511.97Hz
Explanation: when there is a relative motion between an observer and a sound source, the frequency of sound wave perceived by the observer is different from the frequency of originally sent out by the sound source.
This is called Doppler effect and given mathematically below as
f' = (v + v') /(v- vs) * f
f' = observed frequency
v = speed of sound in air = 340m/s
v' = velocity of observer= 45m/s
vs = velocity of source relative to observer = - 36m/s ( the negative sign came as a result of the fact that the velocity of the source is in opposite direction to the velocity of the observer)
f = original frequency of sound source = 500Hz
f' = (340 + 45)/{340 -(-36)} * 500
f' = 385/ (340 + 36) * 500
f' = 385/ 376 * 500
f' = 1.0239 * 500
f' = 511.97Hz
The centripetal acceleration is the ratio of the tangential speed and the
radius of the shell.
The tangential speed of the part of the shell is approximately <u>0.12961 m/s</u>
Reasons;
The widest diameter of the egg, d = 12 cm = 0.12 m
The given centripetal acceleration, 
= 0.28 m/s²
Required:
The tangential speed of the bird.
Solution;
Where;
v = The tangential speed
Which gives;
v² = 0.28 m/s² × 0.06 m = 0.0168 m²/s²
v = √(0.0168 m²/s²) ≈ 0.12961 m/s
The tangential speed, v = <u>0.12961 m/s</u>

Answer:
ANS : .Energy spent on spraying =
Explanation:
<em>Given:</em>
- <em>Radius of mercury = 1cm initially ;</em>
- <em>split into
drops ;</em>
Thus, volume is conserved.
i.e ,
- Energy of a droplet =
Δ
Where ,
- <em>T is the surface tension </em>
- <em>ΔA is the change in area</em>
Initial energy 
Final energy 
∴ .Energy spent on spraying = 
ANS : .Energy spent on spraying =
Given:
Object in circular motion 25 m/s
1 second to go quarter circle
Required:
Centripetal acceleration:
Solution:
Acceleration = v2/r
Where v is the velocity and r is
the radian
Substituting the values into the
equation,
Acceleration = v2/r = (25
m/s)2/(4*pi/180) = 8952.47 m2/s2
