What forces exist when I calculate the acceleration force from the speed?
Q. I calculated the acceleration of a vehicle based on the speed, using (Vf-Vi)/t. If I calculate the Acceleration Force of the vehicle as m*a what forces are included in this result? Are friction, gravity and air resistance forces included in the result?
Asked by Eleazar - Mon Apr 26 19:27:47 2010 - Physics - 1 Answers - Comments
A. There is no such thing as "acceleration force". What you really mean is net force. Net means total, it has nothing to do with cargo nets. The net force is the vector sum of ALL outside forces acting on the body of interest. And you really don't know which forces compose this net force unless you know more specifics of the situation.

What happens to forces inside an atom when a proton is added? What if a neutron is added?
Q. The questions in details: What happens to the forces (electromagnetic, nuclear, and repulsive) inside the atom when a proton is added to the nucleaus? What happens to the forces inside the atom when a neutron is added to the nucleus?
Asked by Kaneya - Thu Oct 18 18:31:36 2007 - Chemistry - 2 Answers - Comments
A. In both cases, the proton is smashed into the nucleus, against the repulsive force; or the neutron "rolls" into the nucleus. In both cases, either the neutron enters the nucleus, creating a new isotope that is unstable relative to beta emission; or the proton enters with so much energy that other nucleon(s) are expelled (or not!). In any case, there is usually a change in the nuclear energy state owing to the nucleon binding force. This leads to the production of a daughter nucleus, which is born in a nuclear excited state. The daughter nucleus decays to ground by emission of characteristic gamma rays.

What were the main driving forces behind the development of ergonomic?
Q. As you may know that ergonomic is a really essential part in designing in order to improve the interaction between the product and users. but can u tell what is the driving forces and why?
Asked by snow_lion1994 - Thu Oct 28 07:22:58 2010 - Homework Help - 1 Answers - Comments
A. In industry, ergonomics was employed by Taylor, Gilbreths, et al to improve the efficiency of operations. More recently it has been used to reduced repetitive motion and strain injuries. With consumer products, the best ergonomic "fit" between person and device usually makes for a product that is more commercially successful. Easier and more comfortable to use means better sales of the product.

What air force security forces units are deployed the most?
Q. I am going into security forces and just would like to know what security forces squadrons are deployed the most. I know the 820th is big with deployments. What are some of the others?
Asked by Matt - Sat May 14 19:23:46 2011 - Military - 4 Answers - Comments
A. Any squadron attached to a base that does not have a nuclear mission or a missile mission. At our previous base our SFS had 6 months on, 6 months off rotation. So,1/2 would deploy, then the next year the other 1/2 would deploy. Current base has a nuc mission, so our SFS does not deploy, nor do they get tasked to augment.

What is the connection between potential energy and non-conservative forces?
Q. Is there even one? Potential energy is usually calculated in reference to a conservative force acting upon an object, not a non-conservative force. But that's what our homework question says: "What is the connection between potential energy and non-conservative forces?" He also goes on and asks us to show how to calculate the potential energy due to sliding friction - I've never heard of this before. Just establish a datum, and the potential energy in this case will always be negative, no? Thanks Cyan, I can't seem to reply below so had to do it up here.
Asked by JasonM - Sat Mar 26 23:07:00 2011 - Physics - 1 Answers - Comments
A. Think about potential energy and kinetic energy. If an object is at the top of a ramp, it has a certain potential energy. When it slides down the ramp (a ramp that is NOT frictionless), it loses some of its energy due to friction. Therefore, not all of the potential energy is converted to kinetic energy. Some of it is lost to friction in the form of heat. If seeing and equation helps you: mgh = 1/2*mv^2 + (frictional component) mgh is potential energy 1/2*mv^2 is kinetic energy

What are the forces acting on two like-charged hanging balloons?
Q. If two balloons are hanging from the ceiling with like charges (positive and positive or negative and negative), they will repel, or spread apart from one another. What are the forces acting on the balloons? I know an electromagnetic force and gravity are acting on them but are there any other forces? Also, say you took gravity out of this situation, would the balloons repel even more?
Asked by Sarah F - Sat Dec 12 13:29:53 2009 - Physics - 1 Answers - Comments
A. 1. Friction. The balloons are touching the ceiling, and that would cause some resistance in the balloons' movement as they repel each other. 2. Air resistance. Although insignificant, as the balloons move away from each other, they need to push the air in their paths out of the way. If the balloons were put in a gravity free room, such as on the Space Shuttle or formerly the Space Station, the balloons would surely repel each other with greater force due to the absence of #1 above.

The normal force is going to counteract what force is opposite to it. which is one of the components of mg. Which would turn out to be (cos18)(m)(g) = normal force. therefore normal force = (cos18)(5.7)(9.8) normally it would be -cos18mg becaue it is opposite but i just considered g to be positive instead since it would cancel out.

Its intermolecular forces are just dispersion forces as it has no oxygen or nitrogen bonded to carbon or hydrogen to introduce dipole attractions.

What is the minimum number of unequal forces whose vector sum can equal zero?
Q. What is the minimum number of unequal forces whose vector sum can equal zero? My answer: I'd say two because the vector sum depends on the angle, not the magnitude of the force, so if we have two vectors with an 180 degree angle between them, their vector sum is zero. Is that right? I'm preparing for an exam, so I appreciate any idea. Thanks! Sorry, I meant 0 degrees angle, not 180.

A. Wrong: every example of what you describe is a counterexample. Say vector 1 = 1 m [north] and vector 2 = 2 m [north] The angle between them 0 and they are not equal. 1 m [north] + 2 m [north] = 3 m [north], which does not equal 0 In general, given two vectors of unequal length, adding them will result in a non-zero vector because in order to have a zero vector sum, the first and second vectors must "cancel out." For example, if you travel left 1 metre, you must travel 1 metre right to return to your initial position. The minimum is three: Three vectors of unequal form a triangle.

What are the forces that drive growth in international trade?
Q. Help. Im not quite sure what is meant by 'forces'. Are they social, political or economic forces?. How about the government deregulating its economy to encourage trade. What are other examples of these forces that drive growth in international trade and is it good for the countries involved?Im pretty sure smaller countries suffer in this process.

A. Globalisation has seen industralisation and increased capitalism. To compete globally requires competitive practices which has resulted in free trade and the lifting of all trade protection, hence deregulation. I would say this is about the forces of globalisation because this is currently what is influencing all economic policital and and social forces.

How do constructive and destructive forces affect Earth's surface?
Q. How do constructive and destructive forces affect Earth's surface? And Compare and contrast what occurs when two oceanic plates collide, when two continental plates collide, and when an oceanic and a continental plate collide.

A. When 2 oceanic plates collide, they form a sort of underwater mountain range. the same thing happens when 2 continental plates collide. When both collide, the continental plate is pushed under the oceanic plate, down to into the earth, where it is recycled by volcanoes. Hope that helps. :)
