Any process that exerts a stress on a rock that eventually causes it to break into smaller fragments is a type of mechanical weathering.
Answer:
It causes the object to slow down or stop.
Explanation:
Friction is a unknown force pressing against another force slightly, making the moving object slow down.
Hope I help :)
The carbon cycles recycles caronatoms(carbon dioxide) and the nitrogen cycle recycles nitrogen.and the carbon cycle makes carbon dioxide and the carbon dioxide goes to the trees ,and the trees get the nitrogen and starts the cycle again.
Answer:
The correct answer is option 'D':During ventricular systole, the left ventricle generates more than 120 mmHg
.
Explanation:
A blood pressure of 120 mm Hg means that during the ventricular systole the blood leaves the ventricles to the rest parts of the body the pressure that it exerts on the walls of the arteries equals pressure exerted by a column of 120 mm of mercury. At the peak flow the pressure should be just exceed 120mm Hg in order to initiate circulation. The excess pressure is needed as we need to overcome the resistance of the blood in the arteries that is at a pressure of 120 mmHg
Answer:
pressure gradient
Explanation:
The correct answer would be pressure gradient.
<em>A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.</em>
In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.
