It's an aspect of geography that delves into the relationship, including the social, economic and spatial interconnections between people and their environment.
The sun’s light and other forms of electromagnetic energy reach the earth by radiation. The mass of the sun acts on the earth (and other planets) by gravity which steers the earth in an almost circular orbit round the central sun.
Answer:440.03 N
Explanation:
Given
horizontal component of acceleration ![(a_x)=800 m/s^2](https://tex.z-dn.net/?f=%28a_x%29%3D800%20m%2Fs%5E2)
vertical component of acceleration ![(a_y)=880 m/s^2](https://tex.z-dn.net/?f=%28a_y%29%3D880%20m%2Fs%5E2)
mass of ball =0.37 kg
Force in horizontal direction![=m\times a_x=0.37\times 800=296 N](https://tex.z-dn.net/?f=%3Dm%5Ctimes%20a_x%3D0.37%5Ctimes%20800%3D296%20N)
Force in vertical direction ![=m\times a_y=0.37\times 880=325.6 N](https://tex.z-dn.net/?f=%3Dm%5Ctimes%20a_y%3D0.37%5Ctimes%20880%3D325.6%20N)
Therefore net force is
![F=F_x+F_y](https://tex.z-dn.net/?f=F%3DF_x%2BF_y)
![|F|=\sqrt{296^2+325.6^2}](https://tex.z-dn.net/?f=%7CF%7C%3D%5Csqrt%7B296%5E2%2B325.6%5E2%7D)
|F|=440.03 N
Answer:
w = w₀ / 2 the angular velocity is half the initial value.
Explanation:
We can analyze this exercise as if we added another disk to obtain a disk with twice the mass, for which if the system is two disks, the angular tidal wave is conserved
initial instant.
L₀ = I₀ w₀
final moment
L_f = I w
the moment is preserved
L₀ = L_f
I₀ w₀ = I w
the moment of inertia of a disk is
I = ½ m R²
we substitute
½ m R² w₀ = ½ (2m) R² w
w = w₀ / 2
for the case of a disk with twice the mass, the angular velocity is half the initial value.
