Answer:
21.67 m/s²
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 49.7 m/s
Radius (r) = 114 m
Centripetal acceleration (a) =?
The centripetal acceleration can be obtained by using the following formula:
a = v²/r
a = 49.7² / 114
a = 2470.09 / 114
a = 21.67 m/s²
Therefore, the centripetal acceleration of the car is 21.67 m/s²
Answer:
This question can only be answered by you.
Explanation:
This question must be tailored specificly to you. whatever your next class is you must write 8 sentences on your walk to it. You can try going into detail about who you saw on the walk. where you went.what people were doing in the hallway. Did you look out a window? what did you see? how long did it take you to walk there? do you usually stop at your locker?
Also dont forget to use a colon ( : ): This can be used when listing things
semicolon (;) : is used as a pause (Seperation) in a long sentence.
Try incorperating some of the five senses in your sentences.
Good luck!
Answer: 479. 425 N
Explanation: the calculation of a body in an elevator obeys Newton law. When it is accelerating upward, the scale reading is greater than the true weight of the person.
It is given by N= m(g+a)
When it is accelerating downward, the scale reading is less than the true weight.
It so given by N = m(g-a)

Answer:
Explanation:
There could be. Not much of the artificial sweeteners are used in the diet colas. (This is measured in mg, which is gram broken down into thousands).
On the other hand a 355 red can of coke has a about 9 grams of sugar in it. That is a great deal. It may make the can of "natural coke" heavier enough to make a difference in it's buoyancy. It could allow the natural coke to sink a bit below the surface.
It is an ideal test for a science fair project for a student in the middle grades.
