Answer: The action from a force can cause an object to move or can speed up accelerate, to slow down (decelerate), to stop, or to change direction. Since any change in velocity is considered acceleration, it could be said that a force on an object results in the acceleration of a object.
Explanation:
One way a farmer could increase the amount of available nitrogen in his fields without adding synthetic fertilizer would be to grow a legume crop to support the development of root nodules.
The right option is a. contour interval
The difference in elevation between the highest and lowest contour lines on a topographical map is called contour interval.
A contour interval is the vertical distance between the two contour lines (highest and lowest) in a topographical map. The contour interval is usually stated explicitly on the right-hand lower part in every map. 20 feet for a 1:24,000 map scale is the frequently used contour interval and different contour intervals is available for different maps.
metalic
Explanation:
Atoms having a valence of electron of 1 or 2 are metals. They belong to the first and second group on the periodic table.
In metallic bonds, atoms of metals and alloys joins together.
- The formation of this type of bond is favored by the low ionization energy and a large number of electrons in the valence shells.
- The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
- Most physical properties of metals can be accounted for by this type of bonding.
