80 POINTS AND BRAINILEST REALLY NEEDED 1. Compare and contrast the volcanic activity at a mid-ocean ridge and at a subduction zone
2.compare and contrast the volcanic activity at a mid-ocean ridge and at a subduction zone
3.how is plate tectonics involved in making mountains and making continents larger? What kind of plate boundary is involved in these processes?
4.is Texas near a subduction zones? jusify your answer using the terms plate boundary and plate tectonics

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?
