The entire lunar surface is covered by a thin layer of dust that is about 2 inches (5.08 cm) deep. The dust has accumulated over time from debris breaking up and falling to the surface. Like other bodies, the moon rotates on its axis. Its slow rate of rotation means that it takes 27...
It will be shown that the rotation of the Earth in the Earth-Moon system can\nbe detected by comparing the deflection of a Foucault pendulum at noon on the\none hand and at midnight on the other hand. More precisely, on 21 June the\nmidnight experiment would give a deflection about 4%...
Modern timekeepingdefines a day as the sum of 24 hours—but that is not entirely correct. The Earth's rotation is not constant, so in terms ofsolar time, most days are a little longer or shorter than that. The Moon is—very gradually—slowing the Earth's rotation because of friction pro...
Humans are creatures of habit, and it’s all too easy for us to fall into monotonous eating patterns. Eating the same things all the time, however, is a recipe for intolerance, allergies, and poor health. With the rotation diet, you’ll get a full range of micronutrients for better over...
Solar sails offer potential for long-duration space exploration missions, enabling spacecraft to reach distant destinations. Hundreds of space missions have been launched since the last lunar mission, including several deep space probes that have been sent to the edges of our solar system. However,...
Polar satellites hover over the poles and monitor the Earth as it rotates beneath them so they can eventually scrutinize the entire Earth. Geosynchronous or Geostationary satellites are attached to a specific location, and their rotation is synchronized with the Earth’s rotation. These are used to...
The height of the sun from point A is larger than from point B by 4.92 degree. If the distance between A and B is 500 km, then how long is the circumference of the earth? (Assume that earth is a perfe At your telescope, you measure the parallax of the ...
The issue with photographing stars is that they seem to move because of earth's rotation – this is why we want to photograph their trails in the first place. With that in mind, there is a delicate balance to find with your exposure that’s more than just how long your shutter is open...
On a spacecraft or on a Moon or Mars colony, astronauts and accompanying microorganisms are expected to remain in indoor-closed and controlled habitats for a long period of time, depending on their life-support systems. However, there is still a gap in knowledge concerning the health consequence...
Year 3 medical students were selected for this study because this is the first point during medical studies in which students have regular clinical interactions with patients. Research has also noted the decline of empathy in medical students during this year [7]. Procedure Students were randomly ...
