1.1 A book lies on a table. This book is not moving because: A there are no forces acting on this book.
B the forces acting on the book are in equilibrium.
C the force that the table exerts on the book is greater than the force
that the Earth exerts on the book.
D the force that the book exerts on the Earth has the same magnitude
as the force that the Earth exerts on the book and therefore they
cancel.​

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

What part of the ear is names after tools, such as the hammer and the anvil?

Area around a charged object where the objects can exert a force on another charged objects is an electric
