Gan astronaut stands on the surface of the moon and drops a dictionary (with a mass of 8 kg ) and a cell phone (with a mass of 200 g ) at the same time from the same height. which will hit the ground first? ignore the effects of atmospheric friction. there is not enough information to say which will hit first. the dictionary will hit the ground first. the cell phone will hit the ground first. they will hit the ground at the same time.

they will arrive to the groundat same time

Explanation:

To find which statement is correct, let's consider solving this problem, let's use Newton's second law to find the acceleration of each body

Dictionary

       W₁ = M a₁

       M g = M a₁

       a₁ = g

Mobile

      W₂ = m a₂

      m g = m a ₂

      a₂ = g

      a₁ = a₂

We can that the two bodies have the same acceleration, as they leave the same height and from rest, we must conclude that they will arrive to the groundat same time

the answer for apex is the lowest

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
