One AU is 148,597,871 km, so 0.7 AU is 104,718,510 km. The velocity of light and other electromagnetic radiations in free space is 299,792.458 km/second, so the time for the round trip is (2 * 104,718,510 / 299,792.458) seconds - or 698.6 seconds (11 minutes, 38.6 seconds.)

Radar signals travel at the speed of light.
Light takes about 8 and a third minutes to travel from the Sun to Earth, one AU.
So, to travel 1.6 (0.8 X 2) AU takes about 1.6 times 8 and a third minutes.
That's about 13 and one third minutes. That's about 800 seconds.

∙ 10y agoRadar travels at the speed of light. So the answer is 16 x the time it takes for light to travel 1 AU.
Light travels 1 AU in about 500 seconds.
So, the answer is about 16 x 500 seconds.
That's 8000 seconds.
You can convert that to minutes or hours, if needed.

The distance is 54,600,000,000m (converted from km) and that divided by the speed of light is 182.1260 seconds apart. It would take 3 minutes, 2.13 seconds to a signal from here to mars.

The time it takes to complete one cycle of a signal is known as?
The time it takes to complete one cycle of a signal is called one period. For example, if the signal has a frequency of one hertz (one cycle per second), the period would be 1 second. A two hertz frequency would mean a ½ second period, or ½ second to complete one cycle.
How many planets Earth signal reaches?
All of them in our solar system, plus all others within a distance of about 100 to 120 light years from us.
Distinguish between a signal element and a data element?
Signal Element Versus Data Element: Let us distinguish between a data element and a signal element. In data communications, our goal is to send data elements. A data element is the smallest entity that can represent a piece of information: This is the bit. In digital data communications, a signal element carries data elements. A signal element is the shortest unit (time wise) of a digital signal. In other words, data elements are what we need to send; signal elements are what we can send. Data elements are being carried; signal elements are the carriers.
How does a microwave use sound energy?
Just a small electronic beeper to signal when cooking is complete, a control key is pressed, etc.
Why is source modulation used in atomic absorption spectroscopy?
Source modulation is employed to distinguish between atomic absorption (an ac signal) and flame emission (a dc signal).
How long would a radar signal take to complete a round-trip between Earth and Mars when the two planets are 1.5 AU apart?
It would take a radar signal 3049600 seconds to complete a round-trip between Earth and Mars. Divide by 60 to get minutes and divide again to get hours.
How long would a radar signal take to complete a round trip between Earth and Venus when they are at 0.3 AU apart?
It would take a radar signal 299.40 seconds to complete a round trip.
How do scientist hope to find out if there is life on other planets?
They hope by getting a signal from the radio waves.
Is it common for gay people to signal to each other with a ring on their middle finger?
No. This is complete nonsense.No. This is complete nonsense.
What is difference between vga and lcd display?
The main difference between the tow is the signal. VGA uses an analog signal and DVI is a digital signal.
What is the difference between signal and wave?

What is relationship between signal spectrum and bandwidth?
Signal Bandwidth is the Bandwidth of particular frequency at which signal is transmitted and Bandwidth of spectrum which can able two show number of signal between Intrest of frequency.
What is the difference between signal processing and signal conditioning?
processing is nothing
What is the definition of orthogonal signal space?
Orthogonal signal space is defined as the set of orthogonal functions, which are complete. In orthogonal vector space any vector can be represented by orthogonal vectors provided they are complete.Thus, in similar manner any signal can be represented by a set of orthogonal functions which are complete.
What is the difference between the modulating signal and the demodulating signal in output of the detector?
Distortion.
