A man travels to a foreign country and smuggles a pair of exotic snakes (one male and one female) back into his country of origin. Fearing that he will be arrested by the police, he releases the snakes into the wild. How will this action most likely affect his local ecosystem? A. There will be a reduction in the native snake population as they compete for resources with the exotic snakes. B. The addition of the exotic snakes will have no effect on the local ecosystem. C. The exotic snakes will become sterile and not be able to reproduce since they are not in their native environment. D. There will be an increase in the number of mice in the local ecosystem in order to provide more food for the snake populations.

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off

Awave travels at a speed of 5.2 m/s. if the distance between crests is 0.40 m, what is the frequency of the wave? use f=v/wavelength a. 13 hz b. 2.1 hz c. 0.077 hz d. 5.6 hz

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
