Answer:In non-uniform circular motion, an object's motion is along a circle, but the object's speed is not constant. In particular, the following will be true. The object's velocity vector is always tangent to the circle. The speed and angular speed of the object are not constant

Explanation:In non-uniform circular motion an object is moving in a circular path with a ... Since the speed is changing, there is tangential acceleration in ... Here is an example with an object traveling in a straight path

1: Радиус окружности постоянен (как при движении по круговой железной дороге или по автомобильной дороге). Изменение в

изменит величину радиального ускорения. Это означает, что центростремительное ускорение не является постоянным, как в случае с равномерным круговым движением. Чем больше скорость, тем больше радиальное ускорение. Частице, движущейся с более высокой скоростью, потребуется большая радиальная сила, чтобы изменить направление, и наоборот, когда радиус круговой траектории постоянен.

2: Радиальная (центростремительная) сила постоянна (как спутник, вращающийся вокруг Земли под действием постоянной силы тяжести). Круговое движение регулирует радиус в зависимости от изменения скорости. Это означает, что радиус круговой траектории является переменным, в отличие от случая равномерного кругового движения. В любом случае уравнение центростремительного ускорения в терминах «скорости» и «радиуса» должно выполняться. Здесь важно отметить, что, хотя изменение скорости частицы влияет на радиальное ускорение, на изменение скорости не влияет ни радиальная, ни центростремительная сила. Нам нужна тангенциальная сила, чтобы повлиять на изменение величины тангенциальной скорости. Соответствующее ускорение называется тангенциальным ускорением.

a 15 kg tv sots on a shelf at a height of 0.3 m. how much gravitational potential energy is added to the television when it is l
nata0808 [166]
Gravitational potential energy can be described as m*g*h (mass times gravity times height).

Originally,
15kg * 9.8m/s^2 *0.3 m = 44.1 kg*m^2/s^2 = 44.1 Joules.

After it is moved to a 1m shelf:
15kg * 9.8m/s * 1 = 147 kg*m^2/s^2= 147 Joules.

To find how much energy was added, we subtract final energy from initial energy:

147 J - 44.1 J = 102.9 Joules.

People in the future may well live inside a rotating space structure that is more than 2 km in diameter. Inside the structure, p
Sergeeva-Olga [200]

Answer:

option B

Explanation:

given,

diameter of the rotating space = 2 Km

Force exerted at the edge of the space = 1 g

force experienced at the half way = ?

As the object is rotating in the circular part

Force is equal to centripetal acceleration.

at the edge

g = ω² r

ω is the angular velocity of the particle

r is the radius.

now, acceleration at the half way

g' = ω² r'

g' = \omega^2 (\dfrac{r}{2})

g' =\dfrac{1}{2}(\omega^2 r)

g'=\dfrac{g}{2}

People at the halfway experience g/2

hence, the correct answer is option B

I don’t understand how to do this
anzhelika [568]

Explanation:

A) Use Hooke's law to find the spring constant.

F = kx

40 N = k (0.4 m)

k = 100 N/m

B) Period of a spring-mass system is:

T = 2π √(m / k)

T = 2π √(2.6 kg / 100 N/m)

T = 1 s

Frequency is the inverse of period.

f = 1 / T

f = 1 Hz
