SHOW WORK A 3 kg object attached to a spring oscillates with an amplitude of 15 cm and a period of 2s. At a time t=0.5s, the object's position is x=9.1 cm.

Determine...

a) the spring constant of the spring.

b) the total energy of the system (in joules).

c) the maximum speed of the object.

d) the position of the object as a function of time. Use a cosine function.

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.

What type of force holds atoms together in a crystal?
