Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence...

What causes the seasons? correct answers The tilt of the Earth's rotation axis to its orbit around the Sun causes parts of the Earth to experience more direct illumination from the Sun and longer days during the summer than the winter. What part of the Earth spins the fastest? correct answers the equator If you were standing at Earth's North Pole, where would you see the north celestial pole relative to your zenith? correct answers at the zenith If the star Polaris has an altitude of ...

This exam is entirely multiple choice or true/false. A=T, B=F TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 1) The photosphere is about 100 times the diameter of the Earth, and large sunspots are larger than our whole planet. 1) 2) Granulation is the most obvious proof of solar convective energy transport. 2) 3) The solar corona is much cooler than the Sun's surface, hence we must wait for a total solar eclipse to glimpse it with the naked eye. 3)...

According to Newton's Second Law of motion, if the net force acting on the object increases while the mass of the object remains constant, what happens to the acceleration? Hint: Remember F = m * a - correct answer Acceleration Increases If the earth were moved to half its current distance from the sun, how would the force of gravity by the sun on the earth change? Hint: Recall the form of the equation that you derived, earlier in the game: "gravitational acceleration (g) is proport...
