Explanation:
Large electrical shifting magnets have concentrated retaining strength to lift dense, ferric objects and a deep-reaching magnetization. An immensely useful materials management technique is these electromagnetic rises.
-- An object with mass 'm' moving at speed 'v' has momentum = (m v) .
-- If a force 'F' acts on the object for a time 't', the object's momentum
changes by the amount (F t) .
Answer:
The force of mutual attraction between the asteroid and the gravity tractor is 0.465 lbf
Explanation:
- <em>In earth, a body that has a weight of 22000 lbf, would have a mass of 22000 lbm.</em>
- The asteroid, if is an sphere, would have a volume of
- The iron has a density of , then the mass of the asteroid would be
- If the distance between the surface of the asteroid and the gravity tractor is 150 ft, and the diameter of the asteroid is 1030 ft, then the distance between the tractor and the center of the asteroid would be =
- The force of attraction between two bodies is described by the Newton's law of universal gravitation: , where is the force of attraction, and are the masses of each body, is the distance between both bodies, and is called the gravitational constant.
- Then if it is supposed that the mass is concenter in the center of each body. The force of attraction would be:
Ya I'm in band so this should be easy person d has a b-flat person c has higher than a b-flat and person b has lower than a b-flat hope this helps I'm in band so I've been learning about notes like this
