Answer:
v = 7121.3 m/s
Explanation:
As we know that the centripetal force for the space shuttle is due to gravitational force of earth due to which it will rotate in circular path with constant speed
so here we will have
here we know that
r = orbital radius = 6370 km + 1482 km
also we know that
now we will have
Answer:
20600N
Explanation:
Given parameters:
Mass of the roller coaster = 515kg
radius = 10m
Speed = 20m/s
Unknown:
Force of the track pushing up on the vehicle = ?
Solution:
The force pulling the roller coaster along the track is the centripetal force.
To find the centripetal force, use the expression below;
F =
where;
m is the mass
v is the speed
r is the radius
Now insert the parameters and solve;
F = = 20600N
Hello!
The answer is Gravity. Lets take a look at the options:
A. Nope, this would be if the shuttle was going horizontal.
B. Again, this would be if the shuttle was going horizontal.
C. Yes! This is the only force that is being overcome by using the rocket thrusts to move up.
D. No, the shuttle is using its thrust rocks to push against gravity.
I hope this helps! :)
Explanation:
Fgravity = G*(mass1*mass2)/D²
G is the gravitational constant, which has the same value throughout our universe.
D is the distance between both objects.
so, now some numbers change
Fgravitynew = G*((1/3)*mass1*2*mass2)/(2D)² =
= G*((2/3)*mass1*mass2)/(4D²) =
= (2/3)* (G*(mass1*mass2)/D²) / 4 =
= ((2/3)/4) * G*(mass1*mass2)/D² =
= (2/12) * Fgravity = Fgravity/6
the new gravitational force will be 16/6 = 8/3 units.
Answer:
food, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight
