Using a gnomon, he measured the sun's angle of elevation at noon on the solstice in Alexandria, and found it to be 1 / 50th of a circle ( 7?2') south of the zenith.
32.
Therefore, the tangent of the angle of elevation of the ball, as seen by the player who is properly positioned to catch it, is directly proportional to the time since the ball was hit.
33.
The disadvantages of guns of larger calibre are that guns and turrets must be heavier; and heavier shells, which are fired at lower velocities, require turret designs that allow a larger angle of elevation for the same range.
34.
This makes them especially useful in celestial navigation : they are a dependable indicator of the direction toward the respective geographic pole although not exact; they are virtually fixed, and their angle of elevation can also be used to determine latitude.
35.
The 5.25 in . calibre with separate ammunition is used for dual High Angle and Low Angle Armament, since it gives the reasonable maximum weight of shell which can be loaded by the average gun's crew for sustained periods at all angles of elevation.
36.
It is not very clear but if the grey line across the foreground is the N17 and given the angle of elevation and bearing of the sun it is; the Abbey lay in a rectangular compound, hard by the road on its eastern side.
37.
:: Probably, " flight angle " refers to either the angle of attack ( the angle of elevation of the " wing surface, " relative to horizon, as a rotation along the pitch-axis ); or to the talk ) 17 : 00, 8 March 2011 ( UTC)
38.
:: : : : Oh, " that's " how it's done-- you shine a ceiling projector at the cloud base and measure the bright spot's angle of elevation with an alidade or theodolite, and then take the tangent of that angle to get the cloud base height.
39.
Instead of a coordinate ( x, y ) it is required to hit a target at distance r and angle of elevation \ phi ( polar coordinates ), use the relationships x = r \ cos \ phi and y = r \ sin \ phi and substitute to get:
40.
A stunt car makes horizontal circles of radius 20m along the inside surface ( with an angle of elevation of 30 degrees ) of a vertical cone . the coefficient of static friction between the tires and the road is 0.25 . find the possible range of speeds of the car.
