The drawing shows three particles far away from any other objects and located on a straight line. the masses of these particles are ma = 363 kg, mb = 517 kg, and mc = 154 kg. find the magnitude and direction of the net gravitational force acting on each of the three particles (let the direction to the right be positive).
particle a is 0.5m from b and b is .25m from all in a astraight line

Amodel rocket with a mass of 0.212 kg is launched into the air with an initial speed of 84 m/s. how much kinetic energy will the rocket have at a height of 214 m? assume there is no wind resistance. 634 j 303 j

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
