Answer
Correct Answer is B,D, F and G
Explanation:
If a kid has any type of delays in his physical or mental growth then he need intervention service.
For example if a kid is not able to walk after 18 month, if a kid is not able to speak properly after 3 years, if a kid of 5 years age has lack of response to typical efforts to engage him in an interaction then these kids need intervention service.
Explanation:
velocity of disc 
lets call (h) 1 m to make it simple.
= 3.614 m/s
m/s pointing towards this:
velocity of hoop=
lets call (h) 1m to make it simple again.
m/s
![\sqrt(gh) = sqrt(hg)so [tex]4×V_d= \sqrt(4/3hg)V_h=\sqrt(hg)](https://tex.z-dn.net/?f=%5Csqrt%28gh%29%20%3D%20sqrt%28hg%29%3C%2Fp%3E%3Cp%3Eso%20%5Btex%5D4%C3%97V_d%3D%20%5Csqrt%284%2F3hg%29V_h%3D%5Csqrt%28hg%29)
The disc is the fastest.
While i'm on this subject i'll show you this:
Solid ball 
solid disc 
hoop 
The above is simplified from linear KE + rotational KE, the radius or mass makes no difference to the above formula.
The solid ball will be the faster of the 3, like above i'll show you.
solid ball: velocity 
let (h) be 1m again to compare.
m/s
solid disk speed
uniform hoop speed 
solid sphere speed
Frame of reference, in simplest terms, describes the state of motion of the observer. The frame of reference may also be described by using a set of coordinates, time and motion. We formulate all our equations and solve them using the frame of reference.
Answer: 0.04139m
Explanation:
First, we need to calculate the weight of the man which will be:
Weight = mass × acceleration due to gravity
Weight = mg
Weight = 92.5 × 9.8
Weight = 906.5N
Then, we calculate the force which will be:
F = kx
mg = kx
x = mg/k
x = 906.5/21900
x = 0.04139m.
The spring stretched for 0.04139m.
