Answer:
The average speed is 
The average speed is different from the average velocity in this question
Explanation:
From the question we are told that
The equatorial radius of Jupiter is 
The period of oscillation of Jupiter is 
Generally the average speed is mathematically represented as

=> 
=> 
Generally in average speed the direction is not considered while in average velocity the direction is considered for the case of this question the movement equitorial point has no direction in that it start from one point and after its periodic motion it still remains at that point
Options: A. Tech A. B. Tech B. C. Tech And B. C. None of the above.
Answer:Tech A and B
Explanation:A shift lever is the lever installed on the steering column or floor of a vehicle which allows the driver to shift gears or change gears, the manual valve position is controlled by shift lever as the shift lever moves the manual valve position changes. The
Ball Plungers are self-contained ball-and-spring devices,used in rolling and detent applications, they are used to position the manual valve in a vehicle.

Answer:
Explanation:
Given that,
Surface area A= 17m²
The speed at the top v" = 66m/s
Speed beneath is v' =40 m/s
The density of air p =1.29kg/m³
Weight of plane?
Assuming that,
the height difference between the top and bottom of the wind is negligible and we can ignore any change in gravitational potential energy of the fluid.
Using Bernoulli equation
P'+ ½pv'²+ pgh' = P'' + ½pv''² + pgh''
Where
P' is pressure at the bottom in N/m²
P" is pressure at the top in N/m²
v' is velocity at the bottom in m/s
v" is velocity at the top in m/s
Then, Bernoulli equation becomes
P'+ ½pv'² = P'' + ½pv''²
Rearranging
P' — P'' = ½pv"² —½pv'²
P'—P" = ½p ( v"² —v'²)
P'—P" = ½ × 1.29 × (66²-40²)
P'—P" = 1777.62 N/m²
Lift force can be found from
Pressure = force/Area
Force = ∆P ×A
Force = (P' —P")×A
Since we already have (P'—P")
Then, F=W = (P' —P")×A
W = 1777.62 × 17
W = 30,219.54 N
The weight of the plane is 30.22 KN
