A radar pulse returns to the transmitter-receiver after a tota far is the the object that reflected the wave? nerreceiver after a total travel time of 10 10 1sl. How 10. Light from the Sun takes 8 minutes and 20 second to reach our planet. Calculate the distance the light travel in this case. 11. One of the closest stars to Earth, other than the Sun, is very very very far. Light from that star takes 4.24 years to reach us. Calculate how far this star is in meters.

    Physics Lab Assignment This particular discovery is also an example of how those who deserve an award sadly are not always the ones who receive it. Read the following passage focusing your attention on the scientific procedures and scientific abilities you have been developing throughout the course. The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for...

    show calculations please! In Astronomy we often deal with distances, or lengths, that range form the very small to the very large. For instance The size of a nucleus is roughly 0.000, 000,000,000,001 meters and the distance to the nearest star is roughly 700,000,000,000 meters. We will talk about these numbers using scientific notation where each zero is counted as ten raised to an exponent equal to the number of zeros. Le the size of a nucleus is 1 x...

    The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for quasars (these are extremely bright, compact and remote objects that emit up to a thousand times as much light as our entire galaxy). For that purpose the research group designed a radio-telescope that was built on the flat fields surrounding Cambridge in central England. This telescope did...

  • Except for a few pigeons, Central Park was deserted

    Except for a few pigeons, Central Park was deserted. Mist hung above the chilled grass. Patches of old snow, scattered here and there, looked like white puddles. The sun hung just above the horizon, casting red and orange streaks across low-hanging clouds. The portly, gray-haired gentleman jogging down the path looked out of place. For one thing, he was dressed in ordinary street clothes, not a sweat suit. Also, every few seconds, he looked anxiously back over his shoulder. Coming...
