Whether E0 galaxy appears to have a “Milky Way” band of star light for someone on a planet in the same galaxy.
![Check Mark](/static/check-mark.png)
Answer to Problem 1RQ
No. E0 galaxy does not appear to have a “Milky Way” band of star light.
Explanation of Solution
Milky Way galaxy is almost disk shaped. Thus, when seen from within it appears like a band of star light.
The two-dimensional representation of E0 galaxies seems almost circular but their actual shape inferred from the radial motion of the galaxies is likely to be spherical, true, flattened or elongated.
Because of the spherical nature of the E0 galaxy, when someone habituated on an exoplanet in that galaxy looks at it, they will see stars scattered all over the sky rather than a band of stars.

- Which of the following best describes how to calculate the average acceleration of any object? Average acceleration is always halfway between the initial acceleration of an object and its final acceleration. Average acceleration is always equal to the change in velocity of an object divided by the time interval. Average acceleration is always equal to the displacement of an object divided by the time interval. Average acceleration is always equal to the change in speed of an object divided by the time interval.arrow_forwardThe figure shows the velocity versus time graph for a car driving on a straight road. Which of the following best describes the acceleration of the car? v (m/s) t(s) The acceleration of the car is negative and decreasing. The acceleration of the car is constant. The acceleration of the car is positive and increasing. The acceleration of the car is positive and decreasing. The acceleration of the car is negative and increasing.arrow_forwardWhich figure could represent the velocity versus time graph of a motorcycle whose speed is increasing? v (m/s) v (m/s) t(s) t(s)arrow_forward

A physics professor did daredevil stunts in his spare time. His last stunt was an attempt to jump across a river on a motorcycle (Fig. P3.63). The takeoff ramp was inclined at 53.0°, the river was 40.0 m wide, and the far bank was 15.0 m lower than the top of the ramp. The river itself was 100 m below the ramp. Ignore air resistance. (a) What should his speed have been at the top of the ramp to have just made it to the edge of the far bank? (b) If his speed was only half the value found in part (a), where did he land?
