imagine you are a teacher of a science class. a student brings in a newspaper article that claims the world will run out of ener

gy by the year 2050 because all the oil will be pumped out of the planet. the student is confused because she has learned in your class that energy can never be created or destroyed.how would you explain to her what "running out of energy" means in the article?

А geostationary satellite moves in an orbit of radius 6300km. Calculate the speed with which it moves in the orbit [π=22÷7]​
azamat

Answer:

15.3 m/s

Explanation:

Radius of orbit= 6400+6300 = 12700 km

Circumference of orbit= 2*(22/7)*12700 =79796.45*10^3 m

Now,

       Speed= Distance / Time

                  = 79796.45*10^3/(24*60*3600)

                  = 15.3 m/s

Since this object is traveling at terminal velocity, what must be the value of Fd? (HINT: how to the lengths of both arrows comp
Juli2301 [7.4K]

The magnitude of the air drag when the object is traveling at terminal velocity is C. 850 Newtons

Explanation:

There are only two forces acting on the object here:

- The force of gravity, of magnitude F_g = 850 N, acting downward

- The air drag, F_d, acting upward

Therefore, the equation of motion for the object is

F_g - F_d = ma

where m is the mass of the object and a its acceleration.

The object in this problem is traveling at terminal velocity: this means that the acceleration is zero, so

a = 0

Therefore the equation becomes

F_d = F_g

which means that the magnitude of the air resistance is equal to the magnitude of the force of gravity:

F_d = 850 N
