The international space station is traveling in a circular path around earth. which of the following is constantly changing? a.) mass b.) weight c.) velocity d.) speed

Answer : correct option is (c) velocity.

Explanation :

When an object is moving with a constant speed in a circular path, it is said to be moving in circular motion.

Speed is defined as distance travelled per unit time. In circular motion object moves with constant speed but it keep on changing its direction i.e. its velocity is constantly changing.

Also in circular motion, the object moves tangentially.

Hence, the velocity of object is constantly changing.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
