What is the power and velocity developed by the motor of an elevator in a hotel in the city of Mérida, if it has a weight of 4500 N and rises to the highest floor that is 98.5 feet from the ground? This is important, please, if you do not know, do not answer, please.
If you know of any errors in this problem (like missing fact or something like that) please say it.

Observations show that interstellar clouds can have almost any shape and

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

You can estimate the degree to which a bond between two atoms is ionic or covalent by calculating the
