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
v
v
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.

Rashid [163]

Answer:

0.43 s

Explanation:

We have the following parameters:

Initial velocity, u = 7.4 m/s

Acceleration of gravity, g = 9.8 m/s^2

Distance, s = 43 in + 10 ft = 1.092 m + 3.048 m = 4.14 m

Time, t = ?

Using the equation of motion s=ut +\frac{1}{2}gt^2, we have

4.14 = 7.4t + 0.5\times9.8t^2

4.9t^2 + 7.4t - 4.14 =0

Using the quadratic formula \dfrac{-b\pm\sqrt{b^2-4ac}}{2a} where a = 4.9, b = 7.4 and c = - 4.14, and solving for the positive value of t only, we have

t = 0.43 s

I have a voltage source of 12V but a light that only burns at 5V. The lamp works on 18 mA. Calculate the resistance that you EXT
ratelena [41]

Answer:

The resistance that will provide this potential drop is 388.89 ohms.

Explanation:

Given;

Voltage source, E = 12 V

Voltage rating of the lamp, V = 5 V

Current through the lamp, I = 18 mA

Extra voltage or potential drop, IR =  E- V  

                                                    IR = 12 V - 5 V = 7 V

The resistance that will provide this potential drop (7 V) is calculated as follows:

IR = V

R = \frac{V}{I} = \frac{7 \ V}{18 \times 10^{-3} A} \ = 388.89 \ ohms

Therefore, the resistance that will provide this potential drop is 388.89 ohms.
