Because gravity has been known to define as a force of attraction between things that have mass.
Answer:
The correct option is;
a- sea surface temperature anomaly, in degrees Celsius
Explanation:
From the diagram related to the question we have two graphs super imposed of Sea surface temperature anomaly, in degrees Celsius and cholera incidence anomaly (%) both plotted against time in years.
On the left the y-axis represents the sea surface temperature anomaly while on the right, the y-axis represents the cholera incidence anomaly (%).
The display of the graph shows the sea surface temperature anomaly in blue.
Helium has only 2 electrons in it's valence shell
So, option D is your answer.
Hope this helps!
8 electron are needed for bonding
Answer:
The coefficient of kinetic friction 
Explanation:
From Newton's second law
If the velocity is constant, that means the summation of all forces must be equal to zero. Draw the free-body diagram to obtain the sums of forces in x and y. It must include the Friction Force, in the opposite direction of the displacement, the weight (
), the Normal Force, which is the is the consequence of Newton's third law and the forces from the two workers.
The sum in y is:
Solving for the 
:
The sum in x is:
Solving for the 
:
The formula of the magnitude of the Friction force is
That means the coefficient of friction is:
