A station X on Earth is 8 x 107 km away from a surface probe on Mars. The probe transmits radiowaves to X at a frequency of 6 x 105 per second. How long does it take the radio waves to get to X?
(a) S7P5A51 (Physical Change - Duration).
Pj Problem of Interest is of type change. Problems of speed, velocity, acceleration and time (duration) are change problems.
Radio waves are a type of electromagnetic radiation, so their speed is the same as the speed of light. which
Speed of light = 3 x 108m/sec.
Time = distance/speed.
Distance covered by radio waves = 8 x 107 x 103 m
So, Time it takes radio waves to get to station X on Earth:
Time = (8 x 1010)/ (3 x 108m/sec) = 2.7 x 102 secs = 270 secs.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of matter and radiant energy. Matter is any kind of mass-energy that moves with velocities less than the velocity of light. Radiant energy is any kind of mass-energy that moves with the velocity of light.
