<span>If two of the masses are at (0, 0) and (L, 0), by symmetry the x-coordinate of the third mass must be L/2, and then by the Pythagorean theorem its y-coordinate must be L(âš3)/2. Thus the position of the third mass is (L/2, L(âš3)/2).
Let each mass be m and C be the position of its center of mass.
Then C = (1/(3m)) (m(0, 0) + m(L, 0) + m(L/2, L(âš3)/2)).
= (1/3) (3L/2, L(âš3)/2).
= (L/2, L(âš3)/6).
That is, X_c = L/2 and Y_c = L(âš3)/6.</span>
Answer:
Avaliar o indivíduo como um todo.
Explanation:
O graduado na capoeira, é uma pessoa que recebe mais respeito pelo grupo. Sendo portanto o objetivo de cada exame interno, ou pelo menos deveria ser em sua vasta maioria avaliar o indivíduo como um todo.
We will use the formula, K.E = mgv
m = mass, g = gravity, v = velocity,
m = 230, g = 10, v = 6
K.E = 230 x 10 x 6 = 13,800 Kg
or 13,800 joules.
I think that we deduce ... so, if a sample of people from, say, china or japan have black hair, I'd deduce or at least make the premise that black hair was very common in china or japan,
Answer:
Triples
Explanation:
Kinetic energy =1/2 mv^2 + 1/2 Iw^2
v= linear velocity
w= angular velocity
I= moment of inertia of object
I = k mr^2 where k is a constant for a particular shaped object
v = rw
w=v/r
Rotational Kinetic energy = 1/2 k m× (v/r)^2 × r^2
Total Kinetic energy = translational Kinetic energy + rotational Kinetic energy
KE = 1/2 (1+k) mv^2
Centripetal acceleration = mv^2/r
When KE is tripled, because 1/2(1+k) is a constant for a particular object, mv^2 part gets tripled. r doesn't appear in the equation of total Kinetic energy. So tripling Kinetic energy doesn't affect r. Therefore centripetal acceleration also gets tripled.
