Which of the Following Best Explains Why an Interstellar Ramjet

question 12

Multiple Choice

Which of the following best explains why an interstellar ramjet could,in theory,achieve continuous acceleration?

• A)It uses fuel that is more efficient than any other known fuel.
• B)It collects its fuel as it goes,rather than having to carry the weight of fuel along with it.
• C)It takes advantage of theoretically possible loopholes in Einstein's theory of relativity.
• D)It has such a large fuel tank that it will essentially never use up all the fuel it carries.
• E)Its speed always gets faster because the effects of time dilation change the rate at which time flows.

Definitions:

Stall Speed

The lowest speed at which an aircraft can fly to maintain level flight, or in automotive, the RPM at which the torque converter transfers power from the engine to the transmission under full load.

Shift Points

Specific engine speeds at which an automatic transmission changes gears, maximizing performance or fuel efficiency.

Governed Rpm

The maximum engine speed set by a governor device, designed to prevent damage to the engine by limiting its operational speed.

Stall Test

A diagnostic procedure used to evaluate the performance of an automatic transmission and torque converter by measuring engine response and behavior under load.
