Okay, we got this problem now- thanks anyway, physics board!

A magnetic field B, that is decreasing with time is directed out of the page and passes through a loop of wire in the plane of the page, as in my drawing (ignore that the dots are not evenly spaced, you can only do so much in paint) Which of the following is true of the induced current in the...

oh you can use F=ma to figure out the acceleration thanks :-) also, how would you know where the first charge the 5 coluombs was in relation the the test charge?

A 40 Micro Coluomb test charge is placed in an electric field produced by a 5 Coloumb charge. It expierences a 6 Newton force. What is the strength of the electric field at this point? If the test charge has a mass of 3 x 10 ^ -20 Kg, what acceleration does it expierence? I Think I could...

70= volume of ice(density of water - density of ice) so from there you would just simplify ohhhhh I get it. Thanks you so much you were a huge help

70 = Density of water (volume ice) + density of ice(volume ice) 70= volume of ice(density of water +density of ice) would that be right?

so [ density of ice(volume ice) + 70 ] / density of water= volume of ice how would you divide it with the seventy still there

densityof ice(volume ice) + 70 = Density of water x volume submerged I can't separate the mass into volume and density of the person because I don't know either of those

thank you by the way :-) You're a huge help

so you would end up with mass of ice + mass of person = density of water x (mass of ice/ density of ice) so you would just simplify it from there, but how would you do that [ m(i) + m(p) ] / density of water= m/ density of ice how would you get both onto one side?

so volume submerged = m/density (sorry if I'm a little slow at this I'm not really great at physics) how would you solve that if you only know the density... You still have two unknown variables

so density= m/v so m=density x volunme submerged, but how would that help you if you don't know the volume submerged.

density = mass/volume , but I only know the density. Also the volume submerged would equal the total volume, but I don't know where to go with that...

AP physics B problem- Buoyant Forces? A slab of ice floats on a freshwater lake. What is the minimum volume of the slab such that a 70 kg man can stand on it without getting his feet wet? The density of ice is 0.922 kg/m^3 and the density of freshwater is 1,000 kg/m^3 I have gotten to...
