Answer:
a) distance halfway = 16.49 [m], displacement halfway = 10.5 [m]
b) distrance traveled increases when the child completes one circuit of the track.
Step-by-step explanation:
a) Distance is a scalar quantity that tells you how much space a body has covered when moving. Displacement is a vector quantity that tells you how far from its initial position and object is after moving.
In this case, the child goes around the track only halfway from point 1 to point 2. We know the circunference or perimeter of a circle to be 2*PI*radius. We also know the child only when halfway, so we need to divide the perimeter by 2, thus we get distance = PI*radius
- distance halfway = (PI)*(5.25) = 16.49 [m]
And now that we know the definition of displacement, we can easily see that the child went from point 1 to point 2 which is located at a distance of 1 diameter from point 1:
- displacement halfway = D = 2*radius = 2(5.25) = 10.5 [m]
b)What happens to the distance when the child completes one circuit? The distance will increase beause he is now completing the circuit so he is covering more ground in his movement:
- distance circuit = 2*(PI)*radius = 2(PI)(5.25) = 32.99 [m]
32.99 is more than 16.49 so we are certain that the distance increases.
Answer:
0.75°C
Step-by-step explanation:
Person A Person B Person C
-3 4 8
-1 -4 -2
0 2 5
2 -3 1
To get Fatima mean value, we have to add all the given values together
= - 3 + 4 + 8 - 1 - 4 - 2 + 0 + 2 + 5 + 2 - 3 + 1
= 9
Estimate is 9 deg above Actual Temperature in 12 readings
The formula for our Mean Value will be, the added values divided by actual temperatures
Added values = 9
Actual temperature = 12
Mean value = 9 ÷ 12 = 0.75°C above actual Temperature
The syntax for the IF statement is as follows:
=IF(condition, value if true, value if false)
therefore, we can enter the information from the problem:
=IF($B$9>=470000,35000,1000)
