What measurements will be made to determine the magnitude of the test-mass centripetal acceleration? (1) the mass of the test-mass. (2) the velocity of the test-mass. (3) the radius of the circular path. (4) the mass of the hanging mass. (5) the spring constant. (6) the period of the orbital motion.

1) dynamometer, 2)  balance, 3) measuring tape, 4) balance , 5)  measuring tape and 6) stopwatch

Explanation:

The quantities that should be measured experimentally for the determination of the quantity are:

1) Centripetal acceleration. The force should be measured, for this a dynamometer is placed in the center of turning radius

2) The masses. To measure this magnitude a balance will be used

3) Circular path radius. A measuring tape that measures from the center

4) Hanging mass. In this case the dynamometer is also used and the value is divided by the acceleration of gravity or if you can remove the mass use a balance

5) The constant of a spring. A measuring tape is used to measure the distance for hanging masses

6) The orbital order. For this magnitude, use a stopwatch for time measurement

a.) travels faster in solids because the particles are closer together.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
