- A mass m is suspended from a massless spring of natural length 90 cm with the spring constant k = 10 Nm and causes the spring to extend by 7.9 cm. Assuming the gravitational field strength g = 9.8 ms², calculate the value of the mass on the spring. Give your answer in Sl units. Answer: Choose... +An astronaut lands on a foreign world and wants to measure the local gravitational field strength where he lands. He takes a 0.31m length pendulum and holds it 4 degrees from the vertical. He then releases the pendulum and measures that it takes 7.85 seconds for the pendulum to swing through 10 cycles of swing. What is the gravitational field strength on the planet?Kepler-10c is another exoplanet orbiting another star. It has a mass that is approximately 17.0 times the mass of the Earth. It has a radius that is approximately 2.4 times the that of the Earth. Stats for the Earth (Given): MEarth = 6×1024[kg]. REarth = 6.4×106[m].

- Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s not cm/s). Answer must be in standard form scientific notation. All angles are to be calculated to the nearest 0.1 deg (tenth of a degree).NOTE: The answer of 85.715 rpm was given to me and was incorrect. What is the correct answer?After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 49.0 cm. The explorer finds that the pendulum completes 90.0 full swing cycles in a time of 132 s. What is the magnitude of the gravitational acceleration on this planet?
