Tidal resonance occurs in the Earth’s ocean(s). The mean widths of the Pacific Ocean, Atlantic Ocean, and Indian Ocean are 16,000 km, 4,500 km, and 7,000 km, respectively; and the mean depth of the three oceans is 4 km. Suppose the tidal period is 12.5 hours, determine quantitatively which of the ocean(s) has/have tidal resonance.
Ex/13: The mean radius of earth is 6400 km.
The acceleration due to gravity at its surface is
9.8 m/s². Estimate the mass of earth.

- Many people mistakenly believe that the astronauts who orbit Earth are "above gravity." Earth's mass is 6×1024kg , and its radius is 6.38×106m (6380 km ). Use the inverse-square law to find a height above Earth's surface at that the force of gravity on a shuttle is about 94% that at Earth's surface. Express your answer to two significant figures and include the appropriate units.arrow_forwardYou may attempt this question 3 more times for credit. In this problem, we will directly calculate the surface gravity and your weight on another planet. In metric, your weight is measured in "Newtons", and 1 Newton = 1 kg m / s². Newton's constant G = 6.67 x 10-11 m³/(kg s²). Earth has a mass = 5.97 x 1024 kg and a radius of 6378 km. You should be able to verify that g = 9.8 m/s² on Earth using the formula for surface gravity. If your mass is 64 kg, you should also be able to verify you should weigh 626 Newtons. If you can do that you should be OK for what's next. The mass of Venus is 4.87E+24 kg, and it's radius is 6.05E+3 km. What is the surface gravity of this planet? (Watch your units!). m/s² If your mass is 64 kg, what would you weigh on Venus? Newtons. Note: Remember if your answer requires scientific notation to use the "e" notation: "1.1 x 105" is "1.1e5" to OWL.arrow_forwardWhat is the difference between tidal volume and vital capacity? Suggest a way you could measure a person’s tidal volume.arrow_forward
- Use the given information to answer the question. The weight of an object above the surface of the Earth varies inversely with the square of the distance from the center of the Earth. If a body weighs 50 pounds when it is 3,960 miles from Earth’s center, what would it weigh if it were 3,980 miles from Earth’s center? Round your answer to two decimal places. The body would weigh ___ pounds if it were 3,980 miles from Earth's center.arrow_forwardCalculate the values of g at Earth’s surface for the following changes in Earth’s properties: (a) its mass is doubled and its radius is halved; (b) its mass density is doubled and its radius is unchanged; (c) its mass density is halved and its mass is unchanged.arrow_forwardWhy do the heights of the tides change over the course of a month?arrow_forward
