An estimated value for gravity at a distance r from the middle of the Earth can be gotten by supposing that the Earth's density is spherically symmetric. The gravity hinge on only on the mass inside the sphere of radius r. All the assistances from outside cancel out as a fall out of the inverse-square law of gravitation. Another result is that the gravity is the same as if all the mass were concentrated at the midpoint. Therefore, the gravitational acceleration at this radius is
g(r) = GM(r) / r²
M(r) = mass enclosed by radius r.
If the Earth had a continual density ρ, the mass would be M(r) = (4/3)πρr³ and the dependence of gravity on distance would be
g(r) = (4/3)πGρr
G = 6.674e-11 m³/kgs²
Answer:
x- component = Fx= 4N
y - component= Fy= 3N
Explanation:
Fx=Fcos∅= 5cos 37= 3.99≅4N
Fy=F sin∅= 5 Sin37= 3.009≅3.01N
the dog pulls the pillow at an angle 37 degrees to the horizontal means it pulls it at an angle 37 degrees with the x- axis.if the line of the force represents the vector F then its horizonatal and vertical components wil be along x-axis and y-axis ie Fx and Fy.
as sin∅= Perpendicular/ Hypotenuse
but we have force F and Fy
so sin∅= Fy/F
or Fy= Fsin∅---------eqA
similarly cos∅= base /hpotenuse
cos∅= Fx/F
Fx= Fcos∅----------eq B
eq A and eq B can be used to determine the values of the rectangular components of the force making an angle with the horizontal
Answer:
an educated guess about the solution to the problem.
Explanation:
the hypothesis is is a specific, testable PREDICTION about what you expect to happen in your study.
Something that is not magnetic
