A change of state is a physical change in a matter. They are reversible changes and do not involve any changes in the chemical makeup of the matter. Common changes of the state include melting, freezing, sublimation, deposition, condensation, and vaporization.
Sure hope this helps you
When the object is moving in the elliptical orbit, it means that the direction of its acceleration should be towards the two foci (plural of focus) of the ellipse to keep the elliptical motion. As force according to the Newton's second law: F = ma, the net force must be in the direction of the acceleration. As far as the magnitude of net force is concerned, you can use Newton's gravitational law to find its magnitude.
Now we know that he is getting a raise by 9%.
So that means we have to find out what is 9% of $58,000.
we can do this by multiplying them.
But first we turn 9% into a decimal.
9% = 0.09
Lets multiply
0.09 x $58,700 = $5,283
So since this is a raise we have to add that 9% to our first value.
$58,700 + $5,283 = $63983
So Frank now earns in his new salary $63,983
Fossil and hydro energy have a nice day
Given: Mass m = 0.50 Kg; Force = Weight = mg F = (0.50 Kg)(9.8 m/s²)
F = 4.9 N
Displacement x = 3.0 cm convert to meter x = 0.03 m
Required: Spring constant k = "
Formula: F = kx
k = F/x
k = 4.9 N/0.03 m
k = 163.33 N/m
