A civilian space traveler lands on an alien planet. A pendulum (L = 0.250 m) is used to find the gravity of the planet. The following graph is provided. Answer the questions based on this information. 1. What is the period and frequency of the pendulum’s motion? Explain or show your work.
2. What is the acceleration due to gravity on the surface of the planet in?

What happens to atoms and chemical bonds during a reaction?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

The plum pudding model of the atom states that ?
