What else can I help you with?
What type of dune forms at right angles to the wind when there is abundant sand a lack of vegatation and a constant wind direction?
Transverse dunes form at right angles to the wind when there is abundant sand, lack of vegetation, and a constant wind direction. They have a symmetrical shape with a gently sloping windward side and a steeper leeward side.
Why electromagnetic deflection is used in tv-crt rather than electrostatic as in cro?
Electromagnetic deflection is used because it can create greater deflection angles of the electron beam compared to electrostatic deflection.
How could you find the deflection in a fight of stairs using hand calculations?
You can find the deflection in a flight of stairs using hand calculations by first measuring all angles and lengths. These can then be entered into a formula which calculates deflection based on these variables.
How do you compare magnetic moments of two magnets using deflection magnetometer?
To compare the magnetic moments of two magnets using a deflection magnetometer, you would place one magnet at a known distance from the magnetometer and measure the angle of deflection caused by its magnetic field. Then, you would repeat the process with the second magnet at the same distance and compare the angles of deflection. The magnetic moment of the magnets can be compared by the ratio of the sine of the angles to the distance and the Earth's magnetic field strength.
What Long sand ridges oriented at right angles to the wind are called dunes?
Sand dunes that are at right angles to the wind are called Transverse Dunes. They form with weak winds and an abundant supply of sand.
What is the difference between ordinary prism or constant deviation prism?
An ordinary prism disperses light based on varying angles of refraction, resulting in different colors being separated at different angles. A constant deviation prism disperses light in such a way that all colors are dispersed at a constant angle, maintaining a consistent level of separation irrespective of wavelength.
What characterizes constant velocity motion on a position time graph?
A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
What is the function of universal joint in vehicle?
To enable constant velocity. It keeps a shaft turning through a range of angles.
What angle do lines of longitude cross with lines of latitude?
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
Why circles has no angles and edges?
A circle has no angles because its circumference is a path tyraced put by a point moving at a constant distance from the centre, and an angle is defined as the junction of two straight lines. A circle has one edge - its circumference.
What are the alpha scattering equipment?
Alpha scattering equipment refers to devices used to study the deflection and scattering of alpha particles when they collide with a target material. This equipment typically includes a particle accelerator to generate alpha particles, a target material to interact with the particles, and detectors to measure the deflection angles and energies of the scattered particles. Examples of alpha scattering equipment include alpha spectrometers and Rutherford scattering apparatus.
Which physical quantities does not have any units?
Pure numbers, including ratios and angles, do not have units. For example, the fine structure constant, the mathematical constant pi, and the coefficients in a balanced chemical equation are all unitless quantities.
