Physics 2425 Example test 1 Question
and answers 100% correct 2025/2026
If a flower is 6.5 cm wide, its width expressed in millimeters is x mm, where x is - correct answer
✔greater than 6.5.
A weight lifter can bench press 124 kg. How many milligrams (mg) is this? - correct answer ✔1.24 × 108
mg
The wavelength of a certain laser is 0.21 micrometers, where 1 micrometer = 1x10-6 m. Express this
wavelength in nanometers. - correct answer ✔2.1 × 102 nm
In addition to 1 m = 39.37 in., the following exact conversion equivalents are given: 1 mile = 5280 ft, 1 ft
= 12 in, 1 hour = 60 min, and 1 min = 60 s. If a particle has a velocity of 4.6 miles per hour,its velocity, in
m/s, is closest to - correct answer ✔2.1 m/s.
The motions of a car and a truck along a straight road are represented by the velocity-time graphs in the
figure. The two vehicles are initially alongside each other at time t = 0. At time T, what is true about
these two vehicles since time t = 0? - correct answer ✔The truck will have traveled further than the car.
The motion of a particle is described in the velocity versus time graph shown in the figure. We can say
that its speed - correct answer ✔decreases and then increases.
When can we be certain that the average velocity of an object is always equal to its instantaneous
velocity? - correct answer ✔only when the velocity is constant
If the fastest you can safely drive is 65 mi/h, what is the longest time you can stop for dinner if you must
travel 509 mi in 11 h total? - correct answer ✔3.2 h
