Linda has a cup of coffee sitting in the cup holder in her car. She has to suddenly slam on her brakes and stop. The cup remaine
wolverine [178]
<h3>Answer:</h3><h2>The Newton's first law of motion will be applied in this situation.</h2>
<h3>Explanation:</h3>

As mention in the question, the car was moving then every object inside the car was also in the motion state with the same velocity as the car had. when the brake applied on the car, the brake only stopped the motion of the car than the objects inside it. According to the first law of motion, due to inertia, the body keeps its state intact until an external force applies to change its state. Because of inertia, the coffee inside the cup was in moving state with the car. When brake applied the coffee spilled out of the car to maintain its state and spread all around. If the cup would keep out of the cup holder, It will move also forward on the applied brake.

In general it is best to conceptualize vectors as arrows in space, and then to make calculations with them using their component
JulijaS [17]

Answer:

The calculated vectors are:

\vec{A}-\vec{B}=(3,-5,-4)

\vec{B}-\vec{C}=(-5,4,0)

-\vec{A}+\vec{B}-\vec{C}=(-6,4,3)

3\vec{A}-2\vec{C}=(-3,-2,-11)

Explanation:

To operate with vectors, you sum or rest component to component. To multiply scalars with vectors, you distribute the scalar with each component of the vector. These are the following rules you must apply in these cases:

\vec{V}+\vec{W}=(V_1,V_2,V_3)+(W_1,W_2,W_3)=(V_1+W_1,V_2+W_2,V_3+W_3) (1)

\vec{V}-\vec{W}=(V_1,V_2,V_3)-(W_1,W_2,W_3)=(V_1-W_1,V_2-W_2,V_3-W_3) (2)

\alpha\cdot\vec{V}=\alpha\cdot(V_1,V_2,V_3)=(\alpha\cdot V_1,\alpha\cdot V_2,\alpha\cdot V_3) (3)

The operations in these cases are:

\vec{A}-\vec{B}=(1,0, -3)-(-2,5,1)=(3,-5,-4)

\vec{B}-\vec{C}=(-2,5,1)-(3,1,1)=(-5,4,0)

-\vec{A}+\vec{B}-\vec{C}=-(1,0, -3)+(-2,5,1)-(3,1,1)=(-6,4,3)

3\vec{A}-2\vec{C}=3(1,0, -3)-2(3,1,1)=(3,0, -9)-(6,2,2)=(-3,-2,-11)

Why are the parts of an atom that electrons occupy called electron clouds?
Anna [14]

Because it's literally impossible to tell exactly where something that size is
located at any particular time.

And that's NOT because it's so small that we can't see it.  It's because any
material object behaves as if it's made of waves, and the smaller the object is,
the more the size of its waves get to be like the same size as the object. 
When you get down to things the size of subatomic particles, it doesn't make
sense any more to try and talk about where the particle actually "is", and we only
talk about the waves that define it, and how the waves all combine to become a
cloud of <em><u>probability</u></em> of where the particle is.

I know it sounds weird.  But that's the way it is.  Sorry.
