Answer:
during a solar eclipse the earth and the sun are lined up so that the moon blocks the sun from our veiw.
the reason the east coast doesn't see it at the same time as the west coast is because of the rotation of the earth and the movement of the moon
hope this helps. :)
Answer:
Beneficial ways communities can be politically active:
to create community organizations that engage in public planning processes and also organise peaceful meaningful protests
Not a beneficial way for communities to be politically active: refuses to cooperate with local government
Answer:
There is the conservation of energy in a harmonic oscillator. As a result, the system amplitude will remain constant. The dissipative forces (i.e. friction) lead to loss of energy in different forms and the system amplitude is reduced due to the reduction in both kinetic and potential energies at the end of each oscillation.
The external forces acting on a driving mechanism must be accounted for at all times. In this case, there is a loss of energy because dissipative forces can be returned back to the system in the presence of the driving to account for the loss in energy.

Explanation:
From the question we are told that
The Young modulus is
The length is
The area is
Generally the force acting on the tibia is mathematically represented as
derived from young modulus equation
Now this force can also be mathematically represented as
So
substituting values
Since the tibia support half the weight then the force experienced by the tibia is
From the above equation the extension (compression) is mathematically represented as
substituting values
From the above equation the maximum force is
