Two blocks, one with a mass of 6 kg and one with a mass of 9 kg, are connected by a rope and are sitting on a frictionless surface. you attach a second rope to the 6 kg block and start pulling with a force of 30 n. what is the tension in the rope between the blocks? ?

Explanation:

Net tension force applied on 6 kg block is given as

here we will have

now we will have

Now the tension between two blocks will pull the other end mass i.e. 9 kg

so we will have

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
