Question

What is the width of the Embraer 170/175?

a) 2^2 meters
b) 2.5 meters
c) 3.5 meters
d) 4 meters

Answer 1

The Embraer 170/175 has a wingspan of approximately 26 meters, so none of the provided options are correct. Additional context questions are answered with proper units conversion and consideration of wave properties and motion kinematics.

Step-by-step explanation:

The width of an Embraer 170/175 is not correctly represented by any of the options provided (2^2 meters, 2.5 meters, 3.5 meters, or 4 meters). The actual width, or wingspan, of the Embraer 170/175 is approximately 26 meters. It's important to have accurate dimensions when discussing the specifications of aircraft for educational and practical purposes.

To address the other questions for context and understanding, here's how they would be answered:

1. A length that is 2.0 x 10-3 of a meter is equivalent to 2.0 millimeters.
2. If you are on a boat in the trough of a wave with an amplitude of 1 meter, the wave height from your position is 2 meters, as wave height is measured from trough to crest.
3. To convert lengths to a numerical value bigger than one but less than 1000 using metric prefixes: (a) 7.59 x 107m can be written as 75.9 megameters (Mm), (b) 0.0074 m is 7.4 millimeters (mm), (c) 8.8 x 10-11 m is 88 picometers (pm), and (d) 1.63 x 103 m is 1.63 kilometers (km).
4. For the last question, the distance a car travels at the speed limit in the time it takes a person to walk the width of a car depends on the speed limit and the walking speed. This would be a practical application question in physics whereby you would use rate and time to calculate distance.
