Answer:

Explanation:

1) Potential energy is energy due to an object's position relative to a reference. The higher the object, the larger its energy.

2) Potential energy is highest at Point A as it is the highest.

3) Kinetic energy is energy due to an object's motion relative to a reference. The fastest the object, the larger its energy.

4) Kinetic energy is highest at Point C as the speed there is the highest.

A solid non-conducting sphere of radius R carries a charge Q distributed uniformly throughout its volume. At a radius r (r <
Svet_ta [14]

Answer:  

Hence the answer is E inside = KQr_{1} /R^{3}.

Explanation:  

E inside = KQr_{1} /R^{3}  

so if r1 will be the same then  

E  \begin{bmatrix}Blank Equation\end{bmatrix} proportional to 1/R3  

so if R become 2R  

E becomes 1/8 of the initial electric field.

Debbie places two shopping carts in a cart corral. She pushes the first cart, which then pushes a second cart. What force is bei
ExtremeBDS [4]
Hey there,

Your question states: <span>Debbie places two shopping carts in a cart corral. She pushes the first cart, which then pushes a second cart. What force is being exerted? 

based by looking at this statement above about Debbie, I understand that she (pushed) Cart (A) first. And then, she exerted (Cart B) next. From the option's that are listed above, I only see two. But from my own words, not from the only (two) options above, I see that (Debbie first exerts the second cart on to the first cart). This reason would be because the first cart is already in the corral. So then she would put the second one in there, this would mean that the second one would push the other one in there. Which means that the velocity would also be in half.

I hope you grabbed my answer in there.

Find the sum of the following vectors A=3i-12j and B=4i+7j<br><br>​
Lady_Fox [76]

Answer:

(I). The sum of the vectors is (7i-5j).

(II). The sum of the vectors is (8i+7j).

Explanation:

Given that,

(I). Vector A A=3i-12j

Vector B B=4i+7j

Suppose, (II). Vector A A=6i+15j

Vector B B=2i-8j

(I). We need to calculate the sum of the vectors

Using formula of sum

\vec{C}=\vec{A}+\vec{B}

Where,

\vec{A}= vector A

\vec{B}= vector B

\vec{C}= sum of the vector A and bPut the value into the formula[tex]\vec{C}=(3i-12j)+(4i+7j)

\vec{C}=7i-5j

(II). We need to calculate the sum of the vectors

Using formula of sum

\vec{C}=\vec{A}+\vec{B}

Put the value into the formula

\vec{C}=(6i+15j)+(2i-8j)

\vec{C}=8i+7j

Hence, The sum of the vectors is (7i-5j).

The sum of the vectors is (8i+7j).
