Remember that a controlled variable is a variable that stays the same thoughout the experiment.
it wouldn't be a. because two different wires were used
the final length of the wax would be your dependent variable, so it wouldn't be c.
the thermal conductivity is the independent variable so it isn't d.
the original length of the wax was the same for both.
So B is your answer.
Answer:
myelinated fibers
Explanation:
The basis for differentiation between gray matter and white matter in the cns is the presence of myelinated fibers in white matter
Answer;
X, Z, Y, W
Explanation;
-Kinetic energy is the energy an object has due to its motion. As long as an object is moving at the same velocity, it will maintain the same kinetic energy.
-The kinetic energy of an object is calculated from the velocity and the mass of the object. K.E =1/2 mv²
-From the formula the velocity is squared which means it can have a significant impact on kinetic energy, thus the higher the velocity the higher the kinetic energy. The kinetic energy is also impacted by the mass of a body, such that the higher the mass the higher the kinetic energy.
