A 2,500-kg car hits a fence with a force of 400 N, and the collision takes one second. What is the impulse?

I think the answer is 6.25 kg-m/s but am not sure. Can anyone clarify this for me?

We all know that a quick and easy way to make cold ice is to put water in the freezer. But take it out and after a while it will warm up and turn back into water. Just as expected.

My exact question is: If you could compress an amount of water into ice - then put that newly compressed ice in a perfect fitting container that would not let the ice expand back into water; Would the ice inside the container stay permently cold? or would the ice in the container warm up to it's surroundings but stay in its solid state?

Does God manage more than one property? Explain why or why not. Over the centuries in many cultures there have often been sightings, drawings and abductions. What do you think? Is there a connection?

i allready know that it is the product of the compression efficiency and mechanical efficiency, but do not understand the difference between the 'overall compressor efficiency' and the 'overall efficiency' of a reciprocating air compressor. please help

of their ship from the shore and come up with values E1 and E2. In the past they are known to have estimated distances with standard deviations of S1 and S2. What should the captain of the ship do to combine these two values to estimate the distance from shore.

Any detailed explanation and/or links would be helpful.

Thanks.

I have come across an interesting statement on the net. It is said in
one article that according to etology (the science studying the behavoral patterns of animals, around 90% of wild animals have never had sexual intercourse. It sounds stunning but perhaps someone could either support or oppose to this statement.

okay, my professor is having me and another guy make some posters for our lab for extra credit. He wants us to come up with some ideas for them, then we are going to make them in Powerpoint.

We may be doing one with some techniques on them on how to do titrations, and some other things.

The other guy thought of a Do's and Dont's poster, but im not entirely sure what all we would put on that.

I will probably go through all the labs we had done earlier in the year again and try to find some things, and we may make one that shows some safety things like the fume hood, shower, eye wash exc.

Anyone have any more ideas of something that would be good for a chem lab? Its basic college chem 1 and 2.
