Homework Statement Figure shows a forearm holding a book. a.) Calculate the force the biceps muscle must exerts to hold the forearm and the book. **all answers should be in three sigdigs. Homework Equations \tau = Frsin\theta F=ma The Attempt at a Solution Well, I assumed that...

Homework Statement 1. What atomic orbital/orbitals are available for bonding for S (Sulfur) and F (Fluorine)? 2. How many electrons are in an orbital formed from the overlapping of two atomic orbitals, which are different? Homework Equations N/A The Attempt at a Solution 1. For this...

I'm not learning Calc until next semester, but I just graphed it and plugged in some values. Thanks guys!

Homework Statement An average of 20 000 people visit the Lakeside Amusement Park each day in the summer. The admission fee is $25.00. Consultants predict that, for each $1.00 increase in the admission fee, the park will lose an average of 750 customers a day. Determine the function that...

Thanks everyone! I'm starting to understand the concepts. :D

Can someone please 'stupify' the definitions of an elastic and inelastic collision? Do objects bouncing off of each other undergo elastic collisions, while objects which stick together undergo completely inelastic collisions? This concept is very confusing to me :S thank you!

hmmm, so, say, if both objects traveled at the same velocities, yet with different masses, before colliding, they would have the same momentums? My physics textbook gave an example of equal momentum between two objects: A high-speed car would have the same momentum as a slow moving truck. And...

The law of conservation states that if two objects have a net force of zero, and if they were to collide with one another, the change in momentum of one object is equal in magnitude, but opposite in direction, to the change of momentum of the other object. Knowing this, what would happen if...

Thanks! :)

oh, I see. So, would the equation be as follows? Work= Applied Force * Displacement = 10N * 2.5m = 25J

Hey guys, I got a test tommorow regarding Work, Efficiency, Conservation of Mass, and all those other things. And I needed help with this question regarding work with friction. Oooh, I wish I was good in physics :( If anyone knows the answer, please post and tell me how to do it properly. Many...

Thanks PhanthomJay! I'll be sure to remember for next time :) and my physics test was killer easy! Let's just hope I pass :)

Hey guys, This is my first time using these forums, so forgive me if I do/post anything wrong! Anyways, I need help on a question...and this might be on a physics test I'm having tommorow. I'm not that great in physics, so I need a bit of help. If anyone can tell me their opinion, please do so...
