Abasketball player can jump to a height of 1.1 moff the ground, so he can easily dunk a basketball.
for such a leap, what is his "hang time" - the time spent in the air after leaving the ground and before touching down again?
express your answer to two significant figures and include the appropriate units.

i think its

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.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
