Answer:
B. An experiment that you don't change any variables.
17. The SI unit for force is N.
18. When an Unbalanced force acts upon and object, the object will change speed and/or direction of motion.
19. Average speed is the speed averaged over a span of time. Instantaneous speed would be the speed at any given instance during that span of time.
20. Acceleration= (final velocity - initial velocity) / time
Final velocity= 0 m/s
Initial velocity= 25 m/s
Time = 40 sec.
So, acceleration (0 - 25) m/s / 40 sec.
Acceleration = -0.625 m/s^2
Answer is: <span>c. they both connect the two hemispheres.
</span>Corpus callosum<span> is a wide </span>commissure<span> beneath the </span>cerebral cortex<span> in the </span>brains<span> of </span>placental mammals. Corpus callosum <span>connects the left and right </span>cerebral hemispheres <span>and enables communication between the hemispheres.
</span>Interior commissure<span> </span>is a bundle of nerve fibers<span>, connecting the two temporal lobes of the cerebral hemispheres across the midline.</span>
