Answer:
Explanation:
velocity of ship with respect to water = 6.5 m/s due north
velocity of water with respect to earth = 1.5 m/s at 40° north of east
velocity of ship with respect to water = velocity of ship with respect to earth - velocity of water with respect to earth
The magnitude of the velocity of ship relative to earth is = 5.66 m/s
Answer:
Pumping a well lowers the water level around the well to form a cone of depression in the water table. If the cone of depression extends to other nearby wells, the water level in those wells will be lowered. The cone develops in both shallow water-table and deeper confined-aquifer systems.
Explanation:
Answer is B: field lines loop around the magnet starting at the North Pole and ending at the south
Answer:
<em>Nonpolar molecules</em>
Explanation:
Nonpolar molecules are those molecules that are produced by the union between atoms that have equal electronegativity, so the forces with which the atoms that make up the molecule attract the electrons of the bond are equal, thus causing the cancellation of these forces. An example of an nonpolar molecule is the Oxygen (O2) molecule. In this molecule each oxygen atom attracts the electrons shared towards itself with the same intensity but in opposite directions, therefore the forces of attraction are annulled and the molecule does not become a dipole.
