During the diving when a diver jumps off from platform he brings her knees and arms closer to the body
This is because when diver is in air he don't have any torque about his center of mass which shows that angular momentum of his body will remain constant during his motion in air
Now we can say product of his moment of inertia and his angular speed will remain constant always
So here if we decrease the moment of inertia of the body during our motion then angular speed will increase so that product will remain constant
and this is what the diver use during his diving
so correct answer will be
<u><em>It decreases her moment of inertia.</em></u>
Answer:
The power of 10 in the given value is 5.
Explanation:
scientific notation is expressed in the decimal form. That means always written in the power of 10 form. The decimal place is put after 1 digit.
Answer: you've been trolled
Explanation:
Responda:
400 g
Explicação:
Dado o seguinte:
Deixe Mass (m1) = m em t1 = 45 ° C
Massa (m2) = 200g em t2 = 15 ° C
Equilíbrio térmico (T) = 35 ° C
Usando a relação:
m1 * C * ΔT = m2 * C * ΔT
Onde m1 e m2 são as massas; C = capacidade de calor específico da água e ΔT é a mudança de temperatura
m1 * ΔT = m2 * ΔT
m * (45 ° C - 35 ° C) = 200 * (35 ° C - 15 ° C)
10 * m = 200 * 20
10 * m = 4000
m = 4000/10
m = 400g
