Answer:

The measurement of the reflected ray will be 110 degrees.

Explanation:

It is given that, a light ray strikes the shiny surface at 70 degrees.

From the given figure, the angle between the incident ray and the surface is 70°. So, the angle between the incident ray and the normal will be 90° - 70° = 20°.

From the laws of reflection, the angle of incidence is equal to the angle of reflection.

So, the angle between the normal and the reflected ray will be 20°. Hence, the measurement of the reflected ray will be 110°.

Hence, the correct option is (B) " 110 degrees ".

A rocket, initially at rest on the ground, accelerates straight upward from rest with constant acceleration 58.8m/s2 . The accel
Zanzabum
Split the operation in two parts. Part A) constant acceleration 58.8m/s^2, Part B) free fall.

Part A)
Height reached, y = a*[t^2] / 2 = 58.8 m/s^2 * [7.00 s]^2 / 2 = 1440.6 m

Now you need the final speed to use it as initial speed of the next part.

Vf = Vo + at = 0 + 58.8m/s^2 * 7.00 s = 411.6 m/s

Part B) Free fall

Maximum height, y max ==> Vf = 0

Vf = Vo - gt ==> t = [Vo - Vf]/g = 411.6 m/s / 9.8 m/s^2 = 42 s

ymax = yo + Vo*t - g[t^2] / 2

ymax = 1440.6 m + 411.6m/s * 42 s - 9.8m/s^2 * [42s]^2 /2
ymax = 1440.6 m + 17287.2m - 8643.6m = 10084.2 m

Answer: ymax = 10084.2m

What is the relationship between distance and sound wave return time?
nekit [7.7K]
The time for the echo to return is directly proportional to the distance. vw = fλ. In a given medium under fixed conditions, vw is constant, so that there is a relationship between f and λ; the higher the frequency, the smaller the wavelength.
