If you don't can you tell me the right one?
Motion is described with respect to a
a. graph b. displacement c. slope d. frame of reference
A:d
Displacement is distance combined with
a. direction b. speed c. velocity d. magnitude
A:a
Displacement vectors of 3 m and 5 m the same direction combine to make a displacement vector that is
a. average distance b. average acceleration c. total time d. slope
A:c
Average speed is the total distance divided by the
a. average distance b. average acceleration c. total time d. slope
A:c
The slope of a distance-time graph is equal to the
a. speed b.acceleration c. displacement d. motion
A:a
Velocity is
a. the slope of a linear graph b. acceleration divided by displacement c. speed with direction d. the same in all reference frames
A:c
Two or more velocities can be combined by
a. graphing the slope b. using vector addition c. calculating the instantaneous speed d. determining the rate
A:b
An instructor gives a demonstration in which he makes a standing wave on a long thin slinky. The slinky is 6 meters long. If you see 3 loops on the slinky when the instructor shakes the end of the slinky at a rate of 3.5 cycles per second, then the speed of transverse waves on the slinky is
Suppose the height of a beanstalk doubles each day and in 36 days it reaches the moon. How many days does it take to reach halfway to the moon. Please give an expaination as well as work.
Thanks!
