1. It depends on the direction of the crosswind
A monkey runs west 4 meters, then realizes he forgot his bananas and 3 meters east. This whole thing takes him 15 seconds. What is the monkey’s velocity?
0.47 m/s
2.14 m/s
9.8 m/s
0.067 m/s
Suppose an airplane is flying due north. If a crosswind begins to blow on the plane, what will happen to the plane’s speed?
Slow down
Speed up
Same speed
It depends on the direction of the crosswind
The acceleration due to the force of gravity on earth is equal to:
9.8 m/s2
9.8 m/s2 * time
The same as on the moon
Using this PowerPoint break timer
This PowerPoint slide uses images, custom animation, and timing to provide a countdown timer that you can use in any presentation. When you open the template, you’ll notice that the timer is set at 00:00. However, when you start the slide show, the timer will start at the correct time and count down by 1-minute intervals until it gets to 1 minute. At that point, it will count down in two 30-seconds intervals to 00:00.
To insert this slide into your presentation
Save this template as a presentation (.ppt file) on your computer.
Open the presentation that will contain the timer.
On the Slides tab, place your insertion point after the slide that will precede the timer. (Make sure you don't select a slide. Your insertion point should be between the slides.)
On the Insert menu, click Slides from Files.
