AYUDA 4. Determine el peso de la siguiente masa: 7kg

A) 9.6N
B) 6.9N

5. ¿Cuál es la masa sobre la tierra de un objeto que pesa 71N?

A) 9.81kg
B) 7.2kg​

which language is it can you tell me

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
