3 Kilometers = ________ meters
Correct Answer
3000
3,000Explanation
The question asks for the conversion of 3 kilometers to meters. The correct answer is 3000 or 3,000. This is because there are 1000 meters in 1 kilometer, so to convert kilometers to meters, you need to multiply the number of kilometers by 1000. In this case, 3 kilometers multiplied by 1000 equals 3000 meters.Rate this question:

2000 milliliters = ________ liters
Correct Answer
2
2.0Explanation
To convert milliliters to liters, we divide the value in milliliters by 1000. Therefore, 2000 milliliters is equal to 2 liters. The answer can be expressed as both 2 and 2.0 since they represent the same value in liters.Rate this question:

36 centimeters = ________ meters
Correct Answer
0.36
.36Explanation
The answer is 0.36 or .36 because 1 meter is equal to 100 centimeters. To convert centimeters to meters, we divide the number of centimeters by 100. In this case, 36 centimeters divided by 100 equals 0.36 or .36 meters.Rate this question:

3.9 kilograms = ______ decigrams
Correct Answer
39000
39,000Explanation
The given question asks for the conversion of 3.9 kilograms into decigrams. To convert kilograms to decigrams, we need to multiply the given value by 10,000 since there are 10 decigrams in 1 kilogram. Therefore, 3.9 kilograms is equal to 39,000 decigrams.Rate this question:

Give your answer to this question with then correct number of significant figures. (3.2 mL) - (2.3216 mL) =
Correct Answer
0.9 mL
.9 mL
0.9mL
.9mLExplanation
The correct answer is 0.9 mL because when subtracting two numbers, the result should have the same number of decimal places as the number with the fewest decimal places. In this case, both numbers have one decimal place, so the result should also have one decimal place.Rate this question:

Give your answer to this question with then correct number of significant figures. (7.2 g) * (6.12 g) =
Correct Answer
44 g
44gExplanation
The product of 7.2 g and 6.12 g is 44 g. The answer is given as 44 g, which is the correct number of significant figures.Rate this question:

Give your answer to this question with then correct number of significant figures. (Watch the units!) (2.122 kilometers) - (2.0 meters) = _______ kilometers
Correct Answer
2.120Explanation
The given question asks for the subtraction of 2.0 meters from 2.122 kilometers. To perform the subtraction, we need to convert the units to the same. Since 1 kilometer is equal to 1000 meters, we can convert 2.122 kilometers to meters by multiplying it by 1000. This gives us 2122 meters. Now, we can subtract 2.0 meters from 2122 meters, which equals 2120 meters. Finally, we convert the result back to kilometers by dividing it by 1000, giving us 2.120 kilometers.Rate this question:

Find the total distance traveled: 2 meters South and 5 meters South
Correct Answer
7 meters
7 m
7.0 meters
7.0 mExplanation
The total distance traveled is 7 meters because both distances given are in the same direction, South. Therefore, we can simply add the magnitudes of the distances, which are 2 meters and 5 meters, to get a total of 7 meters.Rate this question:

Find the total displacement traveled: 2 meters South and 5 meters South
Correct Answer
7 meters
7 m
7.0 meters
7.0 mExplanation
The total displacement traveled is 7 meters because both distances are in the same direction (South) and can be added together.Rate this question:

Find the total distance traveled: 2 meters South and 5 meters North
Correct Answer
7 meters
7 m
7.0 meters
7.0 mExplanation
The total distance traveled can be found by adding the distances traveled in each direction. In this case, the person traveled 2 meters south and then 5 meters north. Since the person traveled in opposite directions, the distance traveled is the difference between the two distances, which is 5 - 2 = 3 meters. Therefore, the correct answer is 7 meters, 7 m, 7.0 meters, 7.0 m.Rate this question:

Find the total displacement traveled: 2 meters South and 5 meters North
Correct Answer
3 meters
3 m
3.0 m
3.0 metersExplanation
The total displacement traveled can be found by subtracting the distance traveled in the opposite direction from the distance traveled in the desired direction. In this case, 2 meters South and 5 meters North cancel each other out, resulting in a net displacement of 3 meters North. Therefore, the correct answer is 3 meters, 3 m, 3.0 m, or 3.0 meters.Rate this question:

Calculate the total displacement traveled (Hint: you may need graph paper): 4 meters North and 3 meters East
Correct Answer
5 meters
5 m
5.0 meters
5.0 mExplanation
The total displacement traveled can be calculated using the Pythagorean theorem. The person traveled 4 meters north and 3 meters east, which forms a right triangle. The hypotenuse of this triangle represents the total displacement. By using the Pythagorean theorem (a^2 + b^2 = c^2), where a and b are the lengths of the legs of the triangle, we can find that the total displacement is 5 meters.Rate this question:
