Carbon is denoted by the symbol C‚ is part of group 14 on the periodic table‚ and is the fourth most abundant element in the universe (by mass). Carbon has an electron configuration of 1s2‚ 2s2‚ 2p2. With 4 valance shell electrons it is expected to form 4 bonds‚ this means carbon is tetravalent. However the s orbitals do not form the same type of bond (with other atoms) as the p orbitals‚ this is because their shapes are different. For example CH4 would have the following bonds: C(s)-H(s)‚ C(s)-H(s)

Ramp and Hangar Safety Introduction: Aviation can be dangerous business‚ but a look at hangar and ramp accidents shows the costs can be high‚ even deadly. Training‚ attitude and reasonable expectations can reduce the number of incidents. Discussion/Analysis: For all glamour‚ aviation is a dangerous business. Pilots and mechanics are well aware of this risks and they are highly trained to manage them. But the same can not be said for many of the ground support workers in aviation ramps and hangars

Cars & Measuring Acceleration Introduction: The Speed of Toy Cars & Measuring Acceleration was investigated by using a ticker timer and changing the angle of the ramp. Changing the angle of the ramp affects the speed and acceleration of the trolley. The speed and acceleration of the trolley was determined by using the ticker timer. Aim: The aim of the practical is to investigate the motion and acceleration of a trolley by using a ticker timer and rolling the trolley down a ramp. Variables: Independent

This is the teaser to an amazing book I read “Acceleration” By: Graham McNamee. Duncan the main leading character of the story discovers a journal belonging to what he thinks is a serial killer and he uses his knowledge of profiling as well as the clues from the journal to try to decipher who the serial

To find the initial velocity of a marble leaving a ramp using time‚ range‚ and background information learned in class. Equipment: The equipment used in this experiment was a toy track and ramp‚ a small marble‚ multiple Physics textbooks‚ meter sticks‚ bright-colored cardstock‚ masking tape‚ sidewalk chalk‚ plastic bag and a cloth. Procedure: Our experimental values include the height that the marble would travel‚ y= 88.1 cm‚ and our ramp angle‚ θ= 44.0°. These independent variables were best

relative to you‚ the car you pass has an acceleration a to the west. However‚ the driver of the other car is maintaining a constant speed and direction relative to the road. Is the reference frame of your car an inertial one? If not‚ in which direction (east or west) is your car accelerating relative to the other car? Determine the Concept No. You are in a non-inertial frame that is accelerating to the east‚ opposite the other car’s apparent acceleration. 3 • [SSM] You are riding in a limousine that

What is the direction of the acceleration vector for each of these situations? Remember that if an object speeds up‚ then the velocity and acceleration vectors are in the same direction. If an object slows down‚ then they are in opposite directions. Any object that is traveling in a vertical direction also experiences acceleration due to gravity. Left: Object travels to left and speeds up. Down: Object is tossed upward. A ball is tossed up into the air with a velocity of 50 m/s. The figure
