How many moles are in 5.0 x 10 *23 atoms of iron?

1 answer:

7 0

1 mole ------------ 6.02 x 10²³ atoms
? moles ----------- 5.0 x 10²³ atoms

moles = 5.0 x 10²³ / 6.02 x 10²³

= 0.830 moles

hope this helps!

A book is pushed off the edge of a table. At what point during the fall will the potential and kinetic energy be equal?

vfiekz [6]

Answer:

KE = PE at half the table Height:

Explanation

AT ANY POINT IN THE BOOK'S FALL,

TOTAL E = PE +KE

THE TOTAL E IS CONSTANT

Before the book is pushed off, the total energy is potential

TOT E=PE =MGH

BEFORE THE BOOK HITS THE GROUND, THE TOTAL E IS KINETIC

TOT=KE = MVXV/2

WHEN KE = PE

KE+PE = MGH (STARTING ENERGY SINCE E IS CONSERVED)

OR PE+ PE = MGH

OR MGH' + MGH' =MGH

OR 2H' =H

H' (NEW HEIGHT) =H/2

What happens to the Sun’s position in the sky as the Earth moves in its orbit from winter to spring? need this ASAP

a_sh-v [17]

Answer: As Earth orbits our Sun, the position of its axis relative to the Sun changes. This results in a change in the observed height of our Sun above the horizon. For any given location on Earth, our Sun is observed to trace a higher path above the horizon in the summer, and a lower path in the winter.
