Two balloons are separated by a distance of 25.5 cm. One balloon is charged with a charge of + 6.25 nC = + 6.25 x 10-9 C and the other balloon is charges with a charge of - 3.5 nC = - 3.5 x 10-9 C. Calculate the magnitude of Coulombic Force between them. Explain what kind of coulombic force will exist between them (attractive or repulsive)?

Uppose we consider the system of the three capacitors as a single "equivalent" capacitor. given the charges of the three individual capacitors calculated in the previous part, find the total charge qtot for this equivalent capacitor. express your answer in terms of v and c.

Multiply or divide to make this english distance conversion. 174 inches = feet (14.5, 58, 2,088, 23)

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
