It cannot be the exact same kind of distortion, because magnetic field attracts only magnetic objects. Also, there is repulsion. Neither of these is true for gravity. So, how else could a magnet attract ?

You have to write in order but here is more.

3. 71/9 4. 36/9 5. 22/3 6. 62/9 7. 29/9 8. 56/9

And they all are fractions

a) If an object is already moving, is a force necessary to keep it going at constant velocity?
yes
b) what ONE WORD goes in the blank:
An obect in motion keeps going because it has __inertia__

inertia would be best described as... (CHOOSE ALL THAT APPLY)
mass
X resistance to change in velocity
X the tendency to maintain constant velocity
the force of gravity
X resistance to acceleration
a force within the object
a property of matter

Newton's first law states: When the _net force_ on an object is zero, the object will _maintain_ constant _velocity_.

Another way of saying this is that, if the total force on it equals zero, an object's _acceleration_ will also be zero.


a) What is the net force on an object if you exert 10 N to the right, 4 N to the left, and an additional 6 N to the left?
0 N no direction

b) If the object was going 15 m/s when you began to apply the forces, how far will it go in the following 2 sec?

This is going to be an extra credit question on an upcoming exam and I can't seem to find the answer. I know its not a mute swan though because i know first hand that they hiss (devil bird!). I've heard that maybe the secretary bird can't, but I can't seem to find anything searching the web. Anyone with real Ornithological knowledge know the answer?

i'm looking for information regarding their chemical structure, the different types of chlorides, their dangers and the damage they can potentially cause to the environment and humans.

Any information is much appreciated.

P.S. before people start telling me to do my own homework, i am doing my own research, just thought i might as well use this site as an untapped resource, theres people with all sorts of knowledge out there.
