Answer:
All materials are superconducting at temperatures near absolute zero kelvin.
Explanation:
All materials are superconducting at temperatures near absolute zero kelvin is false concerning superconductors.
Answer:
average velocity include total displacement whereas average speed include total distance
Answer:
Explanation:
a) KE = (1/2) * m * (
) = F * d = 14m * 200N = 2800 m/N or 2.8 * 
m/N
b) 0J and 0m/s (if Marcella stopped after going 14 meters)
c) Known from part (a) that KE = 2800 J = F1 * d1,
2800J = F1 * (14m - 1m) => F1 = 2800J/13m = 215.384 N
These are connective tissues,which plays in structural support and the one that holds bones together.ligaments are one crucial of it,it is made of densely packed collagen fibers that connect bone to bones
Answer:
In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction. This makes the atoms in these substances strongly magnetic—but they are not yet magnets. To become magnetized, another strongly magnetic substance must enter the magnetic field of an existing magnet.
