In designing a backyard water fountain, a gardener wants to stream of water to exit from the bottom of one tub and land in a second one. the top of the second tub is 0.5 m below the hole in the first tub, which has water in it to a depth of 0.15 m. how far to the right of the first tub must the second one be placed to catch the stream of water?

To solve this problem it is necessary to apply the concepts related to the kinematic equations of movement description.

From the definition we know that the speed of a body can be described as a function of gravity and height

Then applying the kinematic equation of displacement, the height can be written as

Re-arrange to find t,

Thus the calculation of the displacement would be subject to

Therefore the required distance must be 0.547m

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.
