Answer:
1) Superposition results in adding the two waves together. Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves. Destructive interference is when two waves superimpose and cancel each other out, leading to a lower amplitude.
I'm sorry thats all I can help with
Answer:
a) The resistance of the calf between the electrodes is 
b) The average resistivity of this part of the leg is 
Explanation:
Hi
a) Using Ohm's law 
, solving for 
, we obtain 
b) The volume of the calf is like a cylinder, so 
, with 
and 
, therefore 
. Then we can use 
, this is the average resistivity of this part of the leg.
Answer + Explanation:
B
She can measure the volume and mass of the marble, the volume and mass of the water, and the mass of the graduated cylinder.

Answer:
Examples of non-inertial reference frames
One clearcut example of an inertial reference frame is an isolated spaceship, far, far away from the Earth, the Sun, the Milky Way Galaxy, and all other massive objects. Fred places a blue ball into a claw at the left end of the ship, and red ball into a claw at the right end of the ship.
Explanation:
Let us say that you are in a car at a stop light. The car is standing still. The light turns green, and the car accelerates forward. While undergoing this acceleration, the car is a non-inertial frame of reference.
