Answer:
200 N/m
20 rad/s
0.31415 seconds
3.18309 Hz
Explanation:
m = Mass of glider = 0.5 kg
x = Displacement of spring
F = Force on spring = 6 N
From Hooke's law we have relation
The spring constant is 200 N/m
Angular frequency is given by
The angular frequency is 20 rad/s
Frequency is given by
The frequency is 3.18309 Hz
Time period is given by
The time period is 0.31415 seconds
Scientists study fossils of plants, animals, and other organisms in order to better understand what life was like on Earth many years ago and how it has changed over time. Fossils are important evidence for the theory of evolution.

Answer:
4°
Explanation:
Given,
chord in the airstream, c = 2 m
speed, v = 50 m/s
lift per unit span = 1353 N/m
density of air, ρ = 1.225 kg/m³
Lift,
From the plot of c_L and angle of attack
Angle of attack is equal to 4°
