What would be the best unit to use to measure the tip of your pencil?
-
Feet
-
Kilometer
-
Millimeter
-
Meter
Correct Answer
A. MillimeterExplanation
The best unit to use to measure the tip of a pencil would be millimeter. Millimeters are a smaller unit of measurement compared to feet, kilometer, and meter, making it more precise for measuring small objects like the tip of a pencil.Rate this question:

How many centimeters are in one meter?
-
10
-
100
-
1,000
-
10,000
Correct Answer
A. 100Explanation
One meter is equal to 100 centimeters. This is because the metric system is based on powers of 10, and there are 100 centimeters in one meter. Therefore, the correct answer is 100.Rate this question:

Which of the following is the formula for calculating speed?
-
Time divided by distance
-
Distance minus time
-
Distance divided by time
Correct Answer
A. Distance divided by timeExplanation
The formula for calculating speed is distance divided by time. This formula is derived from the concept that speed is defined as the distance traveled per unit of time. By dividing the distance traveled by the time taken, we can determine the speed at which an object is moving.Rate this question:

A weather forecaster may give the speed and velocity of a storm.
-
True
-
False
Correct Answer
A. TrueExplanation
A weather forecaster may give the speed and velocity of a storm because they use various tools and techniques to track and monitor storms. By analyzing data from radar systems, satellite imagery, and weather models, forecasters can determine the storm's direction and speed. Velocity refers to the speed of an object in a specific direction, so it is possible for a forecaster to provide both the speed and direction of a storm, which gives the storm's velocity. Therefore, it is true that a weather forecaster may give the speed and velocity of a storm.Rate this question:

What shoud you come to class prepared with everyday?
-
Planner, textbook, notebook
-
Pen or Pencil
-
Willingness to learn & Good manners
-
All of the above
Correct Answer
A. All of the aboveExplanation
You should come to class prepared with a planner, textbook, and notebook to keep track of assignments and take notes. You should also bring a pen or pencil to write with. Additionally, having a willingness to learn and good manners are important for creating a positive learning environment. Therefore, all of the above options are necessary for being prepared for class.Rate this question:

What would be the best unit to measure a flag pole?
-
Millimeter
-
Centimeter
-
Meter
-
Mile
Correct Answer
A. MeterExplanation
The best unit to measure a flag pole would be meter because it is a commonly used unit for measuring length and is appropriate for measuring objects of this size. Millimeter and centimeter would be too small for a flag pole, and mile would be too large. Meter provides a practical and suitable measurement for a flag pole.Rate this question:

What is the speed of something that moves 400 meters in 4 minutes?
-
10 m/min
-
100 m/min
-
10 mph
-
100 mph
Correct Answer
A. 100 m/minExplanation
The speed of something that moves 400 meters in 4 minutes can be calculated by dividing the distance traveled by the time taken. In this case, the speed is calculated as 400 meters divided by 4 minutes, which equals 100 meters per minute. Therefore, the correct answer is 100 m/min.Rate this question:

What is the difference between speed and velocity?
-
There is no difference.
-
Speed has no direction but velocity does.
-
Speed is the measurement of direction.
-
None of the above.
Correct Answer
A. Speed has no direction but velocity does.Explanation
Speed and velocity are both measurements of how fast an object is moving, but they differ in one key aspect - direction. Speed is a scalar quantity that only considers the magnitude of the object's motion, regardless of the direction. On the other hand, velocity is a vector quantity that not only includes the magnitude of the object's motion but also takes into account its direction. Therefore, the correct answer is that speed has no direction, while velocity does.Rate this question:

Why is the International System of Units used by scientists around the world?
-
To communicate more clearly.
-
It is based on the number 10.
-
Calclations with this system are easy.
-
All of the above.
Correct Answer
A. All of the above.Explanation
The International System of Units (SI) is used by scientists around the world because it allows for clear communication, is based on the number 10, and makes calculations easier. By using a standardized system, scientists can ensure that their measurements and data are easily understood and comparable across different countries and disciplines. The use of base 10 units simplifies calculations and conversions, making it more efficient and accurate. Therefore, all of the given reasons contribute to the widespread adoption of the SI system by scientists globally.Rate this question:

What is the speed of something that moves 3,600 cm in 40 sec?
-
90 cm/sec
-
900 cm/sec
-
9 cm/sec
-
None of the above
Correct Answer
A. 90 cm/secExplanation
The speed of something that moves 3,600 cm in 40 sec can be calculated by dividing the distance traveled by the time taken. In this case, 3,600 cm divided by 40 sec equals 90 cm/sec. Therefore, the correct answer is 90 cm/sec.Rate this question:

What is the average of these 3 speeds: 78 mph, 59 mph, and 65 mph?
-
82.7
-
74.5
-
67.3
-
44.2
Correct Answer
A. 67.3Explanation
The correct answer is 67.3. This is the average of the three given speeds: 78 mph, 59 mph, and 65 mph. To find the average, you add up all the speeds and then divide by the total number of speeds. In this case, the sum of the three speeds is 78 + 59 + 65 = 202. Then, you divide 202 by 3 (the total number of speeds) to get the average, which is 67.3.Rate this question:

What measurements did we use for determining the speed of the Shake-N-Go cars?
-
Mi/min
-
Ft/sec
-
In/sec
-
Cm/sec
Correct Answer
A. Cm/secExplanation
The speed of the Shake-N-Go cars was determined using the measurement of cm/sec. This unit is commonly used to measure speed and represents the distance traveled in centimeters per second. It is a precise measurement that allows for accurate calculations of the cars' speed.Rate this question:
