Answer:
Hey
Your answer is the one on the bottom
Newton's first law states that objects in motion will remain in motion (unless acted on by an external force) and that objects at rest will remain at rest.
On earth, if you throw a ball it will hit the ground and the friction between the grass and ball will slow it down. If the ground was frictionless then it would keep going forever.

Answer:
south
cross sectional area of the beam
Explanation:
v = Velocity of ions =
Number of ions per =
Charge density would be the product of number of ions per and the charge of electrons multiplied by 2 as they are doubly charged.
Current density is given by
The current density is
The direction of the current density is opposite to the movement of the charged particle. The particles are moving north so the direction of current density will be to the south.
Current is given by
where A is the cross sectional area of the beam .
So the cross sectional area of the beam is required to determine the total current in this ion beam.
Step 1 : Get your supply list together
Step 2 : Pick what model you want to do
Step 3 : Ask for a partner
Step 4 : Complete the model and take your time.
Step 5 : Read the directions carefully
Answer:
3.19 s
Explanation:
We know,
s = ut + ( 1/2 * a * t^2 )
13.2 = 0*t + ( 1/2 * 2.6 * t^2 )
t^2 = 13.2/1.3 = 10.1538
t = 3.19
