Question: Has anyone ever heard about Jesus’s half brother Haute Karl?

Haute Karl was a reserved man. He stayed home and studied science while his brother would go out and do magic tricks to entertain others and make a celebrity out of himself. Haute Karl was not religious, and believed his brother to be extremely mentally unstable. Not much else is known about this guy, but here is a little verse that mentions him:

Billy “Zeus” Bob 4:69: And that there Haute Karl down over there sateth down and readeth his books, while Jesus tried to walk on water, nearly drowningeth. Karl saved Jesus then looketh him in the face and said “Jesus, you son of a bitches”.

Well, there you go. Now you know about the half brother of Jesus. Feel free to spread the word, and mention him at church the next time you go.

Answer: And his one and a half brother, Cleveland Steamer, the biologist who worked as the man with 6 legs as the Human Spider in the circus.

No one talks about him because Jesus was arachnophobic.

Question: Electric field Experiment help. Equipment used is conductive paper and voltage probe?

Mapping an Electric Field Lab ,
Equipment used , Electric power source , mounting board , galvanometer , two probes , conductive paper and template paper.

1.) why dose the galvanometer register 0 when its two leads are placed on same spot of the conductive paper!!!!??

also , why as you move along the equipotetinal line , the E field vary in strength? why isn’t it all the same?

Thank you , please explain the answer so i understand the theory behind it

Answer: If the two leads are toughing the same spot, then there can be no potential difference between them. No pd , no current. No current, no reading.

The field strength can be deduced from the closeness of the equipotentials. If the equipotentials are bunched up, then the field strength will be high ( and perpendicular to the potential lines ). As you move along any potential line, you will come to regions where the lines fan out. With bigger gaps between the equipotentials you are in a region of weaker field strength.

It seems reasonable – on the short, direct line between the terminals on the paper, there is the greatest field strength and along an arching route between the terminals the field strength is bound to be less ( because of lower Volts per metre . )

Question: Science hw help please!?

on my science homework sheet there is a question i wasn’t taught anything about. Here it is :

Sodium hydrogen carbonate (bicarbonate of soda) is soluble in water. Describe an experiment you could do in a lab, which could find out how much of it could be dissolved in 20cm3 of water.

Thanks
another question is ‘ why is it useful to know how soluble a fertilizer is’??

Answer: Ah, I never listen in Chemistry but here goes;
Bicarbonate of soda is soluble so therefore water can go into it and it will soon dissolve. I would say you need a beaker of water containing a volume of 20cm3. Then add a spoonful of carbonate in, stir and leave for 10 seconds and record results and then repeat the steps until no more carbonate will dissolve.
