Answer:

Rays

Explanation:

The moon was formed about 4.5 billion years ago according to most accepted Giant-impact theory. The Lunar surface has shows the following surface features:

Mares-The dark areas of the moon are filled with lava. These smooth and large areas can be seen from the Earth as well. These are about 3 billion years old.

Crater- These are formed when meteoroid impacts the surface. A depression is formed. Thousands of depressions are present of moon's surface. Lundar surface is continuously bombarded by the small meteors. The largest crater is the Tycho crater.

Mountains and ranges- are the bumps on the surface of the moon. These were formed about 4 billion years ago.

Rills- the cracks present on the lunar surface due to motion of its surface.

Rays- these features were last to form. These are bright rays - streaks of debris which radiate out from large impact craters.

If a flea can jump straight up to a height of 0.410 m , what is its initial speed as it leaves the ground?

aivan3 [116]

Initial velocity = $v_0$

acceleration in the downward direction = -9.8 $\frac {m}{s^2}$

Final velocity at the highest point = 0

Maximum height reached = 0.410 m

Now, Using third equation of motion:

$\(v^2 = {v_0}^{2} + 2aH$

$\(0^2 = {v_0}^{2} - 2 \times 9.8 \times 0.410$

${v_0}^{2} = 2 \times 9.8 \times 0.410$

$v_0 = 2.834 \frac {m}{s}$

Speed with which the flea jumps = $2.834 \frac {m}{s}$

If the wavelength of an s-wave is 23,000 m, and its speed 4500 m/s, what is its frequency?

wolverine [178]

Answer:

5 metre.

Explanation:

Wavelength = Velocity / Frequency

= 23,000/ 4,500

= 5 metre.

A laser beam is incident at an angle of 33.0° to the vertical onto a solution of cornsyrup in water.(a) If the beam is refracted

Answer:

488.08706 nm

$6.14644\times 10^{14}\ Hz$

231715700.28346 m/s

Explanation:

n denotes refractive index

1 denotes air

2 denotes solution

$\lambda_0$ = 632.8 nm

From Snell's law we have the relation

$n_1sin\theta_1=n_2sin\theta_2\\\Rightarrow n_2=\dfrac{n_1sin\theta_1}{sin\theta_2}\\\Rightarrow n_2=\dfrac{1\times sin33}{sin24.84}\\\Rightarrow n_2=1.29649$
