Dejamos caer un objeto desde lo alto de una torre y medimos el tiempo que tarda en llegar al suelo que resulta ser de 0,02 minutos. calcula : a) la altura de la torre, b) la velocidad al impactar al suelo.

a) 11.76 m/s  b) 7.056 m

Explanation:

The described situation is as follows:

An object is dropped from the top of a tower and when measuring the time it takes to reach the ground that turns out to be 0.02 minutes.

This situation is related to free fall, this also means we have constant acceleration, hence the equations we will use are:

(1)  

(2)  

Where:  

Is the final velocity of the object

Is the initial velocity of the object (it was dropped)

is the acceleration due gravity

is the height of the tower

is the time it takes to the object to reach the ground

b) Begining with (1):

(3)  

(4)  

(5)  This is the final velocity of the object

a) Substituting (5) in (2):

(6)  

Clearing :

(7)  

(8)  This is the height of the tower

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

because if the tool that you are using is not balanced it there would be false mass.
