Answer:
the time it takes for one complete back and forth swing
Explanation:
the Mark's is showing you the time it swings back and forth
Answer:
not really
Explanation:
pangea took million of years to separate. Years by Years the continents move. for example The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year. And there movent is due to the activity beneath the earths crust. The plates are moved by currents in the magma at the very surface of the earths mantle , which then in turn cause things like earthquakes and volcanic eruptions.
In scientific notation", that number would be written as
6.81 x 10⁻⁴ .
Answer:
Homeostasis: When bacteria or viruses that can make you ill get into your body, your lymphatic system kicks in to help maintain homeostasis.
Metabolism: The processes of making and breaking down glucose molecules are example of metabolism.(respiration and photosynthesis)
Growth:The liver continues to form new cells to replace senescent and dying ones.
Hope these examples help you.
I attached a Diagram for this problem.
We star considering the system is in equlibrium, so
Fm makes
with vertical
Fm makes 70 with vertical
Applying summatory in X we have,
![\sum F_x = 0](https://tex.z-dn.net/?f=%5Csum%20F_x%20%3D%200)
![W+1.4-Fm cos(70)](https://tex.z-dn.net/?f=W%2B1.4-Fm%20cos%2870%29)
We know that W is equal to
![W= 0.06*100N = 6N](https://tex.z-dn.net/?f=W%3D%200.06%2A100N%20%3D%206N)
Substituting,
![Fm cos (70) = W+1.4N](https://tex.z-dn.net/?f=Fm%20cos%20%2870%29%20%3D%20W%2B1.4N)
![Fm cos (70) = 6N + 1.4N](https://tex.z-dn.net/?f=Fm%20cos%20%2870%29%20%3D%206N%20%2B%201.4N)
![Fm = \frac{7.4}{cos(70)}](https://tex.z-dn.net/?f=Fm%20%3D%20%5Cfrac%7B7.4%7D%7Bcos%2870%29%7D)
![Fm = 21.636N](https://tex.z-dn.net/?f=Fm%20%3D%2021.636N)
<em>For the second part we know that the reaction force Fj on deltoid Muscle is equal to Fm, We can assume also that</em> ![\beta = \theta](https://tex.z-dn.net/?f=%5Cbeta%20%20%3D%20%5Ctheta)
