When the bells are charged up, the left bell acquires a positive charge, the right bell a negative charge. When this occurs, the

nut that is suspended between the two bells experiences a torque (it lines itself up with a line between the two bells) but it doesn't experience a net force. What does this tell us about the charge on the nut

Answer:

Thus simply tells us that The nut has no net charge and so therefore, There will be a negative charge on the left side, and an equal positive charge on the right side

What temperature is required to transfer waste heat to the environment for a heat engine to be 100 percent efficient?
OLEGan [10]
This can be seen as a trick question because heat engines can typically never be 100 percent efficient. This is due to the presence of inefficiencies such as friction and heat loss to the environment. Even the best heat engines can only go up to around 50% efficiency.

What is the difference between electric force and electricity
FromTheMoon [43]

Answer:

Electrostatic force is force between two charges separated by distance in space while gravitational force is the force between two masses separated by a distance. Electrostatic force is either repulsive or attractive while gravitational force is always attractive

Discuss the pros and cons of fission and fusion reactions.
Jet001 [13]

<u>Fission</u>: -

<u>Pros</u>:

- "It does not contribute to the air pollutants in the environment."

- "It does not need costly energy fuels."

- "It is capable of providing energy for 2 to 3 years."

- "It does not make global warming worse."

- "It produces a nuclear reaction that is important."

- "It helps with the field of astronomy."

<u>Cons</u>:

- "It can harm the environment in a way that it disposes waste."

- "It poses a risk to public health."

- "It can cause deadly and costly accidents."

- "It has the potential to open the door for terrorists to create powerful weapons."

<u>Fusion Reactions</u>: -

<u>Pros</u>:

- "Clean energy ."

- "Virtually limitless fuel available ."

- "No chain reaction. Easier to control or stop than fission ."

- "Nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei) ."

- "Little or no nuclear waste. Core remains radioactive for only 100 years. Possibly radioactive structural elements ."

- "Very low fuel cost."

<u>Cons</u>:

- "Unproven (it will take another years of research to explore it on commercial scale) ."

- "Commercial power plants will be very expensive to build ."

- "Requires extremely high temperatures .

If cold fusion could be achieved, it would be much easier to implement."

A frame hanging on a wall is held by two cables. The tension in each cable is 30 N, and the cables make an angle of 45° with the
Vesna [10]

Answer:

(D) 42.4N

Explanation:

Since the frame is at rest, the net force acting on it must be 0. There are three forces acting on it: the gravity and the opposing forces of the two cables.

Since the gravity is a vertical force, we are only interested in the vertical components of the remaining forces. The net force equation is

F_net = 0 = F_g -2 * F_y

The vertical force of one cable (using the information in the drawing) is:

F_y = 30N * sin 45 deg = 21.21N

Now the weight can be determined:

0 = F_g - 2 * F_y

F_g= 2 * F_y = 2 * 21.21N = 42.4N

The weight of the frame is about 42.4N.
