Which of these best describes the relationship between the incident ray, the reflected ray, and the normal for a curved mirror?(

1 point)
The angle that the incident ray makes with the normal is different than the angle that the reflected ray makes with the normal. All points on a curved mirror have the same normal.
The angle that the incident ray makes with the normal is different than the angle that the reflected ray makes with the normal. All points on a curved mirror have the same normal.

The angle that the incident ray makes with the normal is the same as the angle that the reflected ray makes with the normal. Different points on a curved mirror have a different normal.

For a curved mirror, all points have the same normal and the angle of incidence is also equal to the angle of reflection.

According to the laws of reflection, the incident ray, reflected ray and normal all lie on the same plane. For a curved mirror, the normal remains the same at all points along the curved mirror.

Again, the angle made between the incident ray and the normal is the same as the angle made between the reflected ray and the normal. Therefore, the angle of reflection is equal to the angle of incidence.

Answer:

Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

In creating his definition of horsepower, James Watt, the inventor of the steam engine, calculated the power output of a horse o
Studentka2010 [4]

Answer:

Part a)

F = 182.3 Lb

Part b)

P = 0.55 HP

Explanation:

Diameter of the circle = 24 ft

Diameter = 731.52 cm = 7.3152 m

now the horse complete 144 trips in one hour

so time to complete one trip is given as

t = \frac{3600}{144} s

t = 25 s

now the speed of the horse is given as

v = \frac{2\pi r}{t}

v = \frac{\pi(7.3152)}{25}

v = 0.92 m/s

Part a)

Now we know that the power is defined as rate of work done

it is given as

P = F v

746 = F(0.92)

F = 810.9 N

F = 182.3 Lb

Part b)

Work done to climb up to 3 m height is given by

W = mgh

now we have

Power = \frac{Work}{time}

P = \frac{mgh}{t}

P = \frac{(70kg)(9.81)(3)}{5.0s}

P = 412.02 Watt

now we know that 1 HP = 746 Watt

so we have

P = \frac{412}{746} = 0.55 HP
