Although neptune is the farthest planet from the sun, it travels in a fixed orbit around the sun and never changes its path. what is the reason for this? a) the magnetic pull of the sun holds neptune in its orbit. b) the gravitational pull of the sun holds neptune in its orbit. c) the nuclear force acting between the sun and neptune holds the latter in its orbit. d) the repulsive force of bodies outside the solar system holds neptune in its orbit.

Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. after the loop terminates, it prints out, on a line by itself and separated by spaces, the sum of all the even integers read, the sum of all the odd integers read, a count of the number of even integers read, and a count of the number of odd integers read, all separated by at least one space. declare any variables that are needed. assume the availability of a variable, stdin, that references a scanner object associated with standard input. that is, stdin = new scanner(system.in); is given.

Let r be a robotic arm with a fixed base and seven links. the last joint of r is a prismatic joint, the other ones are revolute joints. give a set of parameters that determines a placement of r. what is the dimension of the configuration space resulting from your choice of parameters?
