In any chemical reaction, the mass of the reactants equals the mass if the product. This result forms the basis of the Law of Conservation. which statement correctly explains why this is a law rather than a theory? It has more scientific evidence supporting it.

It has both independent and dependent variables.

It has been tested with the latest laboratory balances, which are very accurate.

It describes a repeatedly observed relationship, but it does not offer an explanation.

What is a good example of instantaneous speed

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
