Speed of light, is generally 299,792,458 m/s. The appropriate choice is "186,283 kilometers per second.

The speed of light is approx. 299,792,458 m/s. This is equal to approximately 186,282.397 miles per second or approximately 300,000 kilometers per second.

Therefore, the correct answer is "186,283 kilometers per second" or "300,000 km/sec". The other choices are incorrect because they are not the correct units for the speed of light. Visible light is an example of electromagnetic radiation that moves at the speed of light. Light and other electromagnetic waves appear to move instantly for many practical uses, but their finite speed has dramatic implications for vast distances and particularly sensitive measurements. The starlight that can be seen from Earth has been out there for a very long time, allowing people to view far-off objects and learn about the evolution of the universe.

4600 j work is done.

To find the amount of work done, the equation for work must be used. This equation is Work = Force x Distance. Force is equal to the mass of the box multiplied by the acceleration due to gravity, and the distance is 18 meters. The angle of 24 degrees above the horizontal must also be taken into account, therefore the cosine of 24 degrees must be used. The mass of the box is 64 kg and the acceleration due to gravity is 9.8 m/s2. After plugging in all the values, the work done is 4600 J.

Answer:

approximately 1.007 * 10^8 m/s^2

Explanation:

To find the ball's centripetal acceleration, we can use the formula a = v^2 / r, where a is the centripetal acceleration, v is the tangential velocity of the ball (the speed at which it moves around the circle), and r is the radius of the circle (the length of the piece of string).

First, we need to find the tangential velocity of the ball. The ball makes 159 complete turns each minute, which means it makes 159 * 2 * pi = 998.46 radians per minute. Since the ball is moving at a constant speed, the tangential velocity is equal to the angle it travels in radians per unit of time, so the tangential velocity of the ball is 998.46 radians per minute.

Next, we need to find the radius of the circle. The length of the piece of string is 0.735 m, and since the ball is swinging in a horizontal circle, the radius of the circle is equal to the length of the piece of string. Therefore, the radius of the circle is 0.735 m.

Now that we have the tangential velocity and the radius of the circle, we can plug these values into the formula to find the centripetal acceleration:

a = v^2 / r

= 998.46^2 / 0.735

= 1.007 * 10^8 m/s^2

Therefore, the ball's centripetal acceleration is approximately 1.007 * 10^8 m/s^2.

Answer:

The wave phenomenon that you are describing is known as the Doppler effect. The Doppler effect occurs when a wave, such as a sound wave, passes by an observer and the pitch of the wave seems to change. This is because the frequency of the wave changes as it moves closer to or farther away from the observer. The pitch of a sound wave is directly related to its frequency, so when the frequency of the wave changes, the pitch will also change. This effect is commonly observed with sound waves, but it can also occur with other types of waves, such as light waves.
