(a) Based on the observations, determine the total mass M of the planet.
(b) Which moon and planet of our solar system is the team observing? (Use literature.)
At its closest approach to Earth, Mars is 57.50 million kilometers away. How long (in minutes) would a
radio signal sent from a future manned mission to Mars take to travel to Earth? (distance = speed x time)

Einstein's mass-energy equation is E=mc 2 , where mass is in kilograms and the speed of light is 3.00×108m/s. The unit of energy is the joule (4.184J=1cal;1000cal=1kcal,1J=1kg⋅m2/s2).
1) Calculate the energy released, in calories, when 1 g of matter is converted to energy, then calculate the energy released, in kilocalories, when 1 g of matter is converted to energy.

- An Unidentified Flying Object (UFO) moving along a line with constant speed was sighted at (8, 9, 10) at noon and at (13, 19, 20) at 1:00 pm. Where was the UFO at 12:20 pm? When, and from where, did it leave the ground (z = 0)? What was the UFO’s speed?arrow_forwardSince 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardWhile looking through the Mt. Palomar telescope, you discover a large planetary object orbited by a single moon. The moon orbits the planet every 7.35 hours with the centers of the two objects separated by a distance roughly 2.25 times the radius of the planet. Fellow scientists speculate that the planet is made of mostly iron. In fact, the media has dubbed it the ''Iron Planet'' and NASA has even named it Planet Hephaestus after the Greek god of iron. But you have your doubts. Assuming the planet is spherical and the orbit circular, calculate the density of Planet Hephaestus.arrow_forward
- From a distance of 300 km above the surface of the Moon, what is the angular diameter in arc seconds of an astronaut in a space suit who has a linear diameter of 0.80 m as seen from above?arrow_forwardThe intensity of light from a central source varies inversely as the square of the distance. If you lived on a planet only half as far from the Sun as our Earth, how would Sun’s light intensity compare with that on Earth? How about a planet 10 times farther away than Earth?arrow_forwardMoon is at the distance 384400 km from Earth and orbits the Earth every ∼28 days. Ifthe radius of the Moon is 1737 km (consider it to be spherical), what is the area of themoon as measured by the observer on Earth? (Hint: Length contraction)arrow_forward
- Calculate how long radio communications from the spacecraft will take when it encounters Mars. The furthest distance from Earth to Mars is 2.66 AU. Remember that 1 AU = 1.5 x 1011 m and that light travels at 3 x 108 m/s. So how long will the radio messages take to travel this greatest distance of 2.66 AU? If two way communication between the Earth and the spacecraft involve a 1 s time lapse before an acknowledging signal is sent by the spacecraft, how long a time is there between sending a command to the spacecraft and receiving a reply?arrow_forwardOn Dec 5, 2022, scientific history was made at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California when nuclear fusion was achieved when the 192 lasers deposited about 2 Megajoules (MJ) of energy into a frozen pea sized deuterium-tritium pellet and ignited the pellet through nuclear fusion to release 3 MJ of energy. The metric prefix mega means million (10^6). a) How much mass (kg) would be required to release 1 MJ of energy?arrow_forward(Answer both qestions very neatly and kindly explain all the terms in it). 1 (a) Perilune of a lunar approach trajectory is 250 km. If v2 = 0.5 km/s, calculate the required value of 6 and the Av at perilune required to place the probe in a circular prograde lunar orbit. {Ans.: 8 = 7.745°, Av = 673m/s} (b) Find the radial speed of the moon on April 30, 2025, at O6:00:00 UT. {Ans.: 56.7 m/s}arrow_forward
