2. A marble of mass 10 g is placed on the track at the starting point. The height attained by the marble on the opposite side is measured. This is repeated five times. Which of the following experimental results would support the explanation of conservation of energy given in Paragraph 2?​

What is magnetic flux? explain faraday's law of induction.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
