Potential energy is an object’s stored energy when it is not moving. Kinetic energy is an object’s energy in motion. You can’t be both moving and not moving at the same time, so PE and KE cannot be equal.

Two particles, each with charge Q, and a third charge q, are placed at the vertices of an equilateral triangle as shown. The tot

Gelneren [198K]

Answer:

D. The total force on the particle with charge q is perpendicular to the bottom of the triangle.

Explanation:

The image is shown below.

The force on the particle with charge q due to each charge Q = $\frac{kQq}{r^{2} }$

we designate this force as N

Since the charges form an equilateral triangle, then, the forces due to each particle with charge Q on the particle with charge q act at an angle of 60° below the horizontal x-axis.

Resolving the forces on the particle, we have

for the x-component

$N_{x}$ = N cosine 60° + (-N cosine 60°) = 0

for the y-component

$N_{y}$ = -f sine 60° + (-f sine 60) = -2N sine 60° = -2N(0.866) = -1.732N

The above indicates that there is no resultant force in the x-axis, since it is equal to zero ( $N_{x}$ = 0).

The total force is seen to act only in the y-axis, since it only has a y-component equivalent to 1.732 times the force due to each of the Q particles on q.

The total force on the particle with charge q is therefore perpendicular to the bottom of the triangle.

You are wearing earbuds or headphones to listen to your music but your family members can hear it as well. They tell you that it

If it’s loud enough for your family to hear it, it’s best you turn it down. It could cause permanent damage to your ear drums if it’s loud enough and you could start to lose your hearing. So if your family were to tell you to turn it down, you should probably just turn it down!

Hello and Good Morning/Afternoon:

Original Question: C₂H₅OH + __O₂ → __CO₂ + __ H₂O

To balance this equation:

⇒ must ensure that there is an equal number of elements on both sides of the equation at all times

Let's start balancing:

On the left side of the equation, there are 2 carbon molecule

⇒ but only so far one on the right side

C₂H₅OH + __O₂ → 2CO₂ + __ H₂O

On the left side of the equation, there are 6 hydrogen molecules

⇒ but only so far two on the right side

C₂H₅OH + __O₂ → 2CO₂ + 3H₂O

On the right side of the equation, there are 7 oxygen molecules

⇒ but only so far three on the left side

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

Let's check and make sure we got the answer:

C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O

2 Carbon ⇔ 2 Carbon

6 Hydrogen ⇔ 6 Hydrogen

7 Oxygen ⇔ 7 oxygen

Thefore the coefficients in order are:

⇒ 1, 3, 2, 3

Answer: 1,3,2,3

Hope that helps!
