2) The 'plum pudding' model of the atom was used by scientists in the early part of the 20th century to explain atomic structure.
Electrons
"Pudding'
(a) Those scientists knew that atoms contained electrons and that the electrons had a
negative charge. They also knew that an atom was electrically neutral overall.
What did this allow the scientists to deduce about the 'pudding' part of the atom?

Describe the function of the endomembrane system? what organelles are involved?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

What is a carrier wave and how does it affect what you hear on the radio
