A=pi r^2
A=( 3.14159.......)(12.77)^2
A= 512.30m^2
You mean like a box sitting on a table.
One force is the force of gravity, pulling downward on the box.
Now, you know that the forces acting on the box must be balanced, because
if they're not, then the box would be accelerating. But it's just sitting there, so
there must be some other force, just exactly the right strength and direction to
exactly cancel the force of gravity on the box, so that the net force on it is zero.
The other force is the force of the table pushing upward on the box. It's called
the "normal force".
The JWST is postioned about 1.5 million kilometers from the earth on the side facing away from the sun
Overweight:25 to 30, obese: over 30
The kinetic energy bc the energy is independent of the gravitational acceleration, and it depends only on the speed and mass. So the last answer
