What conclusions about impulse can the students make?
Students perform an experiment in which they drop
two eggs with equal mass from a balcony. In the first
trial, the egg hits the ground and breaks. In the second
trial, the egg hits a foam cushion and does not break
or bounce.
The impulse was greater in the first experiment
because the egg broke.
The impulse was greater in the second experiment
because the egg did not break
The impulse was the same in both experiments
because the egg came to a stop.
The impulse cannot be determined without the
mass and velocity of the eggs.

Apositive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
