As the satellite panels extend, the angular velocity decreases due to drag force, and hence it will cause a decrease in the angular momentum of the satellite.
<h3>
What is angular momentum?</h3>
Angular momentum is defined as the quantity of rotation of a body, which is the product of mass, velocity and radius.
L = mvr
L = mωr²
where;
- m is mass of the object
- v is velocity
- r is radius
- ω is angular velocity
As the satellite panels extend, the angular velocity decreases due to drag force, and hence it will cause a decrease in the angular momentum of the satellite.

Answer:
52433.1
Explanation: you just multiply the numbers
Answer:
27.66 s
Explanation:
Space station creates artificial gravity by rotational movement about its axis .
The object inside also move in circular motion creating centrifugal force which creates acceleration in them .
centrifugal acceleration = ω² R where ω is angular velocity and R is radius of the cylindrical space station .
R = 380 /2 = 190 m
Given
ω² R = g = 9.8
ω² = 9.8 / R
= 9.8 / 190
= 5.15x 10⁻²
ω = 2.27 x 10⁻¹
= .227 rad / s
2π / T = .227 ( T is time period of rotation )
T = 2π / .227
= 27.66 s .
outside of the space station they will experience zero acceleration , because they are rotating around the earth.
Answer:
12s
Explanation:
Given parameters:
Velocity = 7.5m/s
Distance = 90m
Unknown:
Time taken = ?
Solution:
Speed is the rate of distance traveled with time. It is mathematically expressed as;
Speed =
Since the unknown is time;
Time =
Insert the parameters and solve;
Time = = 12s
