Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Explanation:
(A "release" of a chemical means that it is emitted to the air or water, or placed in some type of land disposal.)
Answer:
2400 cm
Explanation:
The milky way has diameter of 100000 light years.
The local group is the collection of galaxies which includes the milky way.
10 million light years is the diameter of the local group.
Hence, the diameter of the scale model of the local group would be 2400 cm
Answer:
Explanation:
Sum all the forces that are acting on the object and what ever the sum is, is what the net force is.
For example if there is a piece of wood sitting on a table the net force would be the sum of the forces that are acting on it, so the force of gravity (which is negative) + the normal force which would equal zero because they are the same value.
