Answer:
the answer is A: voluntary reflexes
Explanation:
because Alcohol poisoning can effect the brain which voluntary is something in the brain
Answer:
, charges are both positive or both negative
Explanation:
The electrostatic force between the two spheres is given by
where
k is the Coulomb's constant
q1 and q2 are the charges on the two spheres
r is the distance between the centres of the two spheres
In this problem, we have
is the force
is the distance between the spheres
because the two spheres have identical charge
Solving the formula for q, we find
And the two charges have the same sign (so, both positive or both negative), since the sign of the force is positive (+0.30 N), so it is a repulsive force.
Given:
I₁ = 0.70 kg-m², the moment of inertia with arms and legs in
I₂ = 3.5 kg-m², the moment of inertia with arms and a leg out.
ω₁ = 4.8 rev/s, the angular speed with arms and legs in.
That is,
ω₁ = (4.8 rev/s)*(2π rad/rev) = 30.159 rad/s
Let ω₂ = the angular speed with arms and a leg out.
Because momentum is conserved, therefore
I₂ω₂ = I₁ω₁
ω₂ = (I₁/I₂)ω₁
= (0.7/3.5)*(30.159)
= 6.032 rad/s
ω₂ = (6.032 rad/s)*(1/(2π) rev/rad) = 0.96 rev/s
Answer: 0.96 rev/s
Ответ:
Пояснение:
Используя уравнение движения S = ut + 1 / 2at², где;
U - начальная скорость = 15 м / с
а - ускорение
s - пройденное расстояние = 20м
t - время = 15 секунд
подставляем в формулу заданные параметры
20 = 15 (15) + 1 / 2a (15) ²
20 = 225 + 225a / 2
20 = 225 + 112,5a
20-225 = 112,5a
-205 = 112,5a
а = -205 / 112,5
а = -1,82
Отсюда ускорение -1,82
The answer is, "an unbalance force has acted on the vehicle". The vehicle will not change its states, unless otherwise there is a force acted upon on the object, that compel it to move in its original position, or to cause to change its direction of motion. This unbalance force cause the vehicle to move in the direction of the applied force.
