The net force is what remains of the pull when we subtract the friction force:
Now, use the law
and solve it for the acceleration
to get the result:
Answer:
No, they are not congruent
Step-by-step explanation:
By CD and EF being congruent, we want to know if they are equal.
What we can simply do here is to find the distance between the points present.
That is, the distance between C and D, the distance between E and F
To get the distances between two points , we use the following equation
D = √(x2-x1)^2 + (y2-y1)^2
For CD, we have
D = √(6 -(-1)^2 + (-7 + 7)^2
D = √(7)^2 = 7 units
For EF, we have
D = √(5-5)^2 + (-5-3)^2
D = √(-8)^2
D = √(64) = 8 units
This clearly shows that they are both not congruent
9 and a fraction would be the answer
Answer: half a lap would take 45 seconds
Step-by-step explanation:
Answer: There is 225 millimeters of slushy originally in the cup.
Explanation:
Since we have given that
Rate at which she drink the slushy = 4.5 millimeters
Time taken to drink the slushy by Mariana = 17 seconds
Total quantity she drank is given by
Still there is left some slushy,
Quantity of slushy left =148.5 millimeters
Total quantity of slushy originally in the cup was given by
Hence, there is 225 millimeters of slushy originally in the cup.
