∙ 17y agoWe have to make a few assumptions first. We assume the angle provided (12.9 degrees) is the plane's attitude, that is, the angle with respect to the horizontal. We also assume the plane's nose is angled toward the ground because you asked for rate of descent (not dissent). We also assume that all of the plane's airspeed is in the same direction as its attitude (which is often not the case in actual flight, where an aircraft's velocity vector may have a different angle than the angle the plane makes with the ground). So, we have an airplane that's traveling at 278 km per hour at an angle that is -12.9 degrees to the horizontal. (The minus sign indicates a downward direction.) That describes a vector having vertical and horizontal components. We are interested in the vertical component, which is given by the formula Vy = Vsin(theta) = 278sin(-12.9) = -62.1. The rate of descent, therefore, is 62.1 km/hr. It is not necessary to use the minus sign if you say "rate of descent," because the minus sign is implied. If you are asked what the vertical velocity is, then you must use the minus sign to indicate whether it's positive (ascending) or negative (descending).

∙ 17y agoTo find the rate of descent, we need to calculate the vertical component of the velocity. We can do this by multiplying the speed of the plane by the sine of the angle of descent. So, 278 km/h * sin(12.9 degrees) ≈ 278 km/h * 0.224 ≈ 62.37 km/h. Therefore, the rate of descent of the plane is about 62.37 km per hour.
Yes.
It is false that a plane flying against a jet stream will travel faster than a plane traveling with a jet stream.
No, the Earth's axis of rotation is at a twenty three and a half degree angle to the plane of its orbit, which is closer to being perpendicular than it is to being parallel. This 23.5 degree "axial tilt" are responsible for, among other things, our seasons.
The plane of elevation of the shoulder girdle is the scapular plane, which is at approximately a 30-degree angle from the frontal plane of the body. This plane is important for proper movement of the shoulder joint and can help reduce impingement and stress on the shoulder muscles and tendons. It is often used as a reference point for exercises and movements involving the shoulder.
The angle between the orbital plane and equatorial plane of the earth (i.e., the angle of axial tilt) is about 23.4 degrees. This gives rise to the earth's seasons.
1.249 radians from the horizontal.
The answer depends on knowing what the plane mirror hhas a 20-degree angle relative to!
A line which rotates through an angle of 10 degree with the positive side of the x-axis of the Cartesian plane is called a 10 degree angle.
A polygon with any number of sides can have a 156 degree angle, as can most non-polygonal plane shapes.
The light ray arrives perpendicular to the plane of the mirror.
Yes.
When two plane mirrors are tilted at an angle of 60 degrees, there are 5 images will be formed.
5 images will be formed and how when two plane mirror are tilted at an angle of 60 degree

A plane mirror can be positioned at a 45-degree angle to reflect light around a corner. When light hits the mirror at the correct angle, it will be reflected off the mirror and change direction to continue traveling around the corner. This method is commonly used in periscopes to see objects that are not in a direct line of sight.
This is not a trapezoid. For all trapezoids (in plane Geometry), the two sets of side angles must be supplementary, or add to 180. No two angles given are supplementary.
