Compare the patterns of field lines in each gravitational field model. What can you conclude about the strength of the field models? Choose all that apply. A) The strength of the gravitational field is the same at the surface of the Sun, Earth, and the moon.
B) The strength of the sun's gravitational field decreases as the distance from the sun increases.
C) The gravitational field at Earth's surface is greater than the gravitational field at the moon's surface. ​

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)

You are given two vectors a⃗ =−3.00ι^ 5.00j^ and b⃗ =5.00ι^ 2.00j^. let the counterclockwise angles be positive.
