The poles are situated within the magnet near its ends. Q. Do both poles of a magnet have the same strength? Ans. Yes, both the poles of a magnet have the same strength. Q. Can you have an isolated pole? Ans. No, magnetic poles occur in paitlic . Q. What is the actual cause of magnelism? Ans. It is due to the motion of electric charges within the substance. the experiment? Ahs. When the needle is brought in the magnetic meridian, the earth's field will exo no influence on it. It will be influenced only by the magnet and the location of the pove will be more accurate. Q. Is the rotat...

What will be the distance covered and the displacement at the end of 2 minutes 20 s? Solution. Given, diameter of the track (d) = 200m Therefore, circumference of the track (π*d) = 200π meters. Distance covered in 40 seconds = 200π meters Distance covered in 1 second = Distance covered in 2minutes and 20 seconds (140 seconds) = meters = meters = 2200 meters Number of laps completed by the athlete in 140 seconds = = 3.5 Therefore, the final position of the athlete (with respect to the initial position) is at the opposite end of the circular track. Therefore, the net displacement will be equal to the diameter of the track, which is 200m. Therefore, the net distance covered by the athlete is 2200 meters and the total displacement of the athlete is 200m. 2. Joseph jogs fro...
An artificial satellite is moving in a circular orbit of radius 42250 kilometres Calculate speed if it takes 24 hours to revolve around the earth?
An artificial satellite is moving in a circular orbit of radius 42050 km. calculate its speed if it takes 24 hours to revolve around the sun? Here we will use the following formula velocity of the satellite v = 2πr/T here r is the radius of the circular path travelled by the satellite = 42250 km and T is the time period = 24 hrs. here, the distance travelled by the satellite in 24 hrs would be the circumference of the circular path of radius 42050 . so, v = (2 X 3.14 X 42050) / 24 = 264074 / 24 :) Draw a diagram showing the motion of a satellite around Earth is the satellite accelerating? WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth. What is a depression on a terrestrial planet or satellite called? A Crater Craters are the most common surface features on many solid planets and moons—Mercury and our Moon are covered with craters. Craters are roughly circular, excavated holes made by impact events. The circular shape is due to material flying out in all directions as a result of the explosion upon impact, not a result of the impactor having a circular shape (almost no impactors are spherical) What is the spinning of an object called? Generally, rotation is t...
