Answer:
14 N to the right
Explanation:
The net force is equal to the resultant of the forces acting on the wagon. In this case, we are considering two forces acting on the wagon:
- The force applied by Marybeth, to the left, of magnitude 34 N
- The force applied by Grant, to the right, of magnitude 48 N
Since the two forces are in opposite directions, in order to find the net force, we must choose a positive direction. Let's take "right" as positive direction, so the net force is:
And the positive sign means the net force is to the right. Due to this net force different from zero, the wagon will have an acceleration to the right, so if the wagon was at rest, it will start moving to the right.
Answer:
The electrons are on the outer shell, there are 10 of them.
Explanation:
There are two in the inner shell and eight in the outer shell, giving us a total of 10 electrons
The type of pure substances that can create elaborate structures is :
( D ) Atoms that are not attracted to each other because they will stay still and end up laying on top of each other.
<h3>What is an Elaborate structure ?</h3>
An elaborate structure is a complex structure formed by the combination of different unrelated parts. Atoms that are un attracted to each other are made of different parts therefore when they come together they will lay on each other, forming an elaborate structure which is complex in nature.
Hence we can conclude that the type of pure substance that can create elaborate structures is Atoms that are not attracted to each other because they will stay still and end up laying on top of each other.

Answer:
mass m = 17.2 kg.
Explanation:
Use potential energy =m*g*h,
so,
m=potential energy/(g*h)
m=96000 J/(9.8*568) = 17.2 kg
Answer:
8 kgm/s
Explanation:
Since the formula for kinetic energy is:
where m is the mass and v is the velocity. If energy is conserved, mass is conserved, it would mean the speed is the same as well. And since the momentum is defined as the product of mass and velocity. The only change in velocity, and also momentum is the direction.
So the ball momentum would change from 4kgm/s to -4kgm/s. A change of 8 kgm/s
