Suppose at a concert a singers voice is radio broadcast all the way around the world before reaching the radio you hold to your ear . How long does this take . __ seconds
I don't understand thisss ! Help me !
To calculate the time it takes for the singer's voice to travel around the world, we need to know the distance the voice covers and the speed at which it travels.
The circumference of the Earth is approximately 40,075 kilometers (or 24,901 miles). To determine the time it takes for the singer's voice to travel this distance, we need to know the speed at which the voice propagates through the medium (such as air or radio waves).
The speed of sound in air is around 343 meters per second, or approximately 767 miles per hour. However, the speed of radio waves is the speed of light, which is approximately 299,792 kilometers per second, or about 186,282 miles per second.
Since the question specifies that the voice is radio-broadcasted, we'll use the speed of light to calculate the time it takes for the singer's voice to reach the radio.
To find the time, we need to divide the distance by the speed.
Distance = circumference of the Earth = 40,075 km
Speed = speed of light = 299,792 km/s
Time = Distance / Speed
Time = 40,075 km / 299,792 km/s
Calculating this gives us the time it takes for the singer's voice to reach the radio, which is approximately 0.133 seconds.
Therefore, the answer is that it takes approximately 0.133 seconds for the singer's voice to travel around the world before reaching the radio you are holding to your ear.
To calculate the time it takes for the singer's voice to reach your radio, you need to know the distance around the world and the speed at which the voice travels. However, you haven't provided any specific details about these values in your question.
If you can provide the distance around the world (in either kilometers or miles) and the speed at which the voice travels (in either km/h or mph), I can help you calculate the time it takes.
