Answer:

50 [m/s].

Explanation:

1) formula is: V-V₀=g*t, where V₀ - final velocity (it is 0), V - required initial velocity, g≈10 [m/s²] and t - elapsed time.

2) according to the formula above:

V=g*t; ⇒ V=5*10=50 [m/s].

Using the rules for significant figures, what do you get when you add 24.545 and 307.3?

lions [1.4K]

When you add 24.545+307.3= 331.845

You will go with the number with the smallest number, which is 307.3.

So answer will be 331.8

Viktor [21]

A long string carries the wave; a segment of the string measuring 6.00 meters in length and weighing 180 grams contains four full wavelengths. The string vibrates sinusoidally at a 50.0 Hz frequency with a 15.0 cm peak-to-valley displacement. The vertical distance between the farthest positive and negative positions is known as the "peak-to-valley" distance. The function that describes this wave traveling in the positive x direction is $y=(7.50 \mathrm{~cm}) \sin \left(\frac{4 \pi}{3} \times-314 t+\phi\right)$ .

$\begin{aligned}& f=500 \mathrm{~Hz} \\&\mu=\frac{180 \times 10^{-3}}{6}=3 \times 10^{-2} K g / m \\&2 A=15 \times 10^{-2} m \\&A=7.5 \times 10^{-2} m \\&4 \lambda=6, \lambda=3 / 2 m \text {. and } v=f \lambda=75 m / \mathrm{sec} \\&\omega=2 \pi f=100 \pi \text { also } K=\frac{\omega}{v}=\frac{4 \pi}{3}\end{aligned}$

If phase constant is $\phi$ then

$\therefore$ equation is $y=7.5 \times 10^{-2} \sin \left[100 \pi t-\frac{4 \pi}{3} x+\phi\right]$

∴ equation is $y=(7.50 \mathrm{~cm}) \sin \left(\frac{4 \pi}{3} \times-314 t+\phi\right)$

A wave is a disturbance that moves from one location to another, carrying energy but not always matter.
The square of the equation provides a probability density map of the locations where an electron has a specific statistical likelihood to be at any given moment in time. Wave functions have no direct physical meaning.

Minute after minute, hour after hour, day after day, ocean waves continue to splash onto the shore. Explain why the beach is not

MAVERICK [17]

Answer: C. Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position.

Explanation:

The reason why the beach is not completely submerged and the reason why the middle of the ocean has not been depleted of its water supply is due to the fact that water isn't transported by ocean waves.

It should be noted that even a single drop of water cannot be brought by the ocean wave to the shore from the middle of the ocean.

The only thing that the ocean waves can bring to the shore is energy. Hemce, the water particles oscillate in their fixed position which is vital in making sure that the beach isn't piled up with water.
