Well, what's a well? Basically, to obtain water found in an aquifer, a well is a hole drilled into the earth. To pull water from the soil, a pipe and a pump are used and a screen filters out un Wells are drilled into the rock as deep as 1,000 feet to enter the water. ... Through a well pump, water flows through this casing. Above level, the well structure is closed off. From a pipe connected between the casing and a pressure tank (generally located in the basement of your house), the water then reaches your home.
C. Oxygen has a different attraction for electrons in H2O than in CO2
the covalent bond between Hydrogen-Oxygen and Carbon-Oxygen is different because the difference of electronegativity (the tendency of an atom to attract a shared pair of electrons towards itself) between Hydrogen and Oxygen is a lot higher than the difference of electronegativity between Carbon and Oxygen. This difference in electronegativity results in separation of partial electric charge creating polar bonds and giving the molecule a polarity.
Answer:
It sticks to the wall due to electrostatics.
Explanation:
When pam rubs a balloon against his hair, and holds it up against the wall, he is basically adding a surplus of electrons which are negative charges to the surface of the balloon.
This motion would make the wall the more positively charged than the balloon. Therefore, when the two charges come in contact with each other, the balloon will stick to the wall because of the rule in electrostatics that opposite charges attract each other.
Voltage (V)= Current (I) * Resistance (R)
I=V/R=140/2=70A
Hope this helps!
