Answer:
is that high school work??? cause I don't know it and I'm about to go to high school
true
Explanation:
this is because melting point and boiling point decreases down the group because they are held together by attractions between positive nuclei and delocalised electrons
6 meters is left because you subtract 12 meters from 6
Answer:
Moment of inertia of the system is 289.088 kg.m^2
Explanation:
Given:
Mass of the platform which is a uniform disk = 129 kg
Radius of the disk rotating about vertical axis = 1.61 m
Mass of the person standing on platform = 65.7 kg
Distance from the center of platform = 1.07 m
Mass of the dog on the platform = 27.3 kg
Distance from center of platform = 1.31 m
We have to calculate the moment of inertia.
Formula:
MOI of disk = ![\frac{MR^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7BMR%5E2%7D%7B2%7D)
Moment of inertia of the person and the dog will be mr^2.
Where m and r are different for both the bodies.
So,
Moment of inertia
of the system with respect to the axis yy.
⇒ ![I_y_y=I_d_i_s_k + I_m_a_n+I_d_o_g](https://tex.z-dn.net/?f=I_y_y%3DI_d_i_s_k%20%2B%20I_m_a_n%2BI_d_o_g)
⇒ ![I_y_y=\frac{M_d_i_s_k(R_d_i_s_k)^2}{2} +M_m(r_c)^2+M_d_o_g(R_c)^2](https://tex.z-dn.net/?f=I_y_y%3D%5Cfrac%7BM_d_i_s_k%28R_d_i_s_k%29%5E2%7D%7B2%7D%20%2BM_m%28r_c%29%5E2%2BM_d_o_g%28R_c%29%5E2)
⇒ ![I_y_y=\frac{129(1.61)^2}{2} +65.7(1.07)^2+27.2(1.31)^2](https://tex.z-dn.net/?f=I_y_y%3D%5Cfrac%7B129%281.61%29%5E2%7D%7B2%7D%20%2B65.7%281.07%29%5E2%2B27.2%281.31%29%5E2)
⇒
The moment of inertia of the system is 289.088 kg.m^2
