Where is UTC the local time?

Dmitrij [34]

UTC is generally adopted as the local time at Prime Meridian (PM).

UTC is an abbreviation for Coordinated Universal Time and it can be defined as a local time standard by which all clocks, time and time zones are regulated around the world.

This ultimately implies that, Coordinated Universal Time (UTC) is generally adopted as the local time at Prime Meridian (PM) because it nominally reflects mean solar time.

A baseball is thrown at an angle of 20° relative to the ground at a speed of 25 m/s if the ball was caught 50 m from the thrower

scoray [572]

Answer:

2.1 s

Explanation:

The motion of the ball is a projectile motion. We know that the horizontal range of the ball is

$d = 50 m$

And that the initial speed of the ball is

$u=25 m/s$

at an angle of

$\theta=20^{\circ}$

So, the horizontal speed of the ball (which is constant during the entire motion) is

$u_x = u cos \theta = 25 \cdot cos 20^{\circ} = 23.5 m/s$

And since the horizontal range is 50 m, the time taken for the ball to cover this distance was

$t=\frac{d}{u_x}=\frac{50}{23.5}=2.1 s$

which is the time the ball spent in air.

Explain an experiment of the phenomenon of rainfall

maks197457 [2]

Unclear/incomplete question. However, I inferred you need an explanation of the phenomenon of rainfall.

<u>Explanation</u>:

Basically, the phenomenon of rainfall follows a natural cycle called the water cycle. What we call <em>'rainfall'</em> occurs when water condensed (in liquid form) in the atmosphere is made to fall down on the ground as tiny droplets as a result of the forces of gravity.

<u>The water cycle makes rainfall possible:</u>

First, water on the earth's surface is evaporated (or is absorbed into) the atmosphere.

Next, it then condensed into liquid form; which later falls to the surface to the ground again. And the process continues.

Light in a vacuum travels at a constant speed of 3x10^8 m/s. If the moons average distance from the earth is 38776106 km how lon

Karo-lina-s [1.5K]

Answer: 258.3 s

Explanation:

The speed $s$ is given by the following equation:

$s=\frac{D}{t}$

Where:

$s=3(10)^{8} m/s$ is the speed of light in vacuum

$D=2(38776106 km \frac{1000 m}{1 km})=7.75(10)^{10} m$ is the double of the distance between Earth and Moon, since the beam of light travels from Earth to the Moon and back to Earth again.
