Answer:
The column number tells us the amount of valence electron the element has
Static friction is the friction between an object at rest and the surface on which it is resting on.
Kinetic friction is the friction between a moving object and the surface on which it moves.
Hopefully you understood and this helps :)
Answer:
Emotions. The amygdala is part of the limbic system of the brain, which is involved with emotions and other reactions to stimuli. The amygdala is a processing center that is hooked up to receive incoming messages from our senses and our internal organs. It is highly involved with different emotional responses
Explanation:
Apply the Pythagorean theorem to get the resultant velocity:
V = 
Given values:
Vx = 57.8m/s
Vy = 5.6m/s
Plug in and solve for V:
V = 58.1m/s
EDIT: Let's get the direction of the resultant velocity as well.
This equation will give the angle of the velocity as measured off of the ground:
θ = tan⁻¹(Vy/Vx)
Again, the given values are:
Vx = 57.8m/s
Vy = 5.6m/s
Plug in the values and solve for the angle θ:
θ = tan⁻¹(5.6/57.8)
θ = 5.5°
The resultant velocity is oriented 5.5° off the ground.
