Chapter 11, Problem 18A
What accounts for the stability of the Space Needle in Seattle?
Expert Solution & Answer
To determine
To explain: The reason behind the stability of the space needle in Seattle
Explanation of Solution
Introduction:
Center of gravity is defined as an imaginary point where the total weight of an object is assumed to be concentrated.
Most of the mass of space needle is below the support base (underground). This means that the center of gravity is underground, so it will not fall over. Thus, space needle in Seattle is in stable equilibrium.
Conclusion:
Therefore, the stability of the Seattle space can not fall because the centre of gravity is below the surface.

- Taking a Hike A hiker begins a trip by first walking 21.0 km southeast from her car. She stops and sets up her tent for the night. On the second day, she walks 46.0 km in a direction 60.0° north of east, at which point she discovers a forest ranger's tower. y (km) Can N W-DE 45.0° 60.0° Tent Tower B x (km) ☹ (a) Determine the components of the hiker's displacement for each day. SOLUTION Conceptualize We conceptualize the problem by drawing a sketch as in the figure. If we denote the displacement vectors on the first and second days by A and B, respectively, and use the ---Select-- as the origin of coordinates, we obtain the vectors shown in the figure. The sketch allows us to estimate the resultant vector as shown. Categorize Drawing the resultant R, we can now categorize this problem as one we've solved before: --Select-- of two vectors.

- Multiverse is called a theory. It has been proposed to account for the apparent and uncanny fine tuning of our own universe. The idea of the multiverse is that there are infinite, distinct universes out there - all with distinct laws of nature and natural constants - and we live in just one of them.

Express your answer with the appropriate units. View Available Hint(s)for Part A Hint 1for Part A. How to approach the question The force the nurse applies to the syringe can be determined from the fluid pressure and the area of the plunger. The minimum force corresponds to the patient's lowest blood pressure. Use the following equality 760mmofHg=1atm=1.013×10^5Pa760mmofHg=1atm=1.013×10^5Pa.arrow_forward
