Explanation:
The force of the roller-coaster track on the cart at the bottom is given by :
, m is mass of roller coaster
Case 1.
R = 60 m v = 16 m/s

Case 2.
R = 15 m v = 8 m/s

Case 3.
R = 30 m v = 4 m/s

Case 4.
R = 45 m v = 4 m/s

Case 5.
R = 30 m v = 16 m/s

Case 6.
R = 15 m v =12 m/s

Ranking from largest to smallest is given by :
F>E>A=B>C>D
Answer:
<em>The number 0.0217 has 3 significant digits</em>
Explanation:
<u>Significant Digits
</u>
These are digits that contribute to the significance of the number. Some rules apply to discard the non-significant digits like:
- Leading zeros
- Trailing zeros (with exceptions)
Our number is 0.0217 has two leading zeros before the 2 because they only occupy space to indicate the order of magnitude of the number. Only the 2,1,7 are significant digits, thus
The number 0.0217 has 3 significant digits
Answer:
344.8 m/s
Explanation:
Looking for speed of sound = meters / sec
2 meters / .0058 seconds = 344.8 m/s
Answer:
Yes it is true saying that 2nd applience use more power than first one
<span>If
the amplitude is equal to 0.25m, then the distance travelled above and below
the equilibrium is also equals to 0.25m. it means if it starts above the
equilibrium, one period will be completed when it returns back to its original
position so, it travels 0.25 below, 0.25m back, 0.25m down and o.25 m when it
comes back to its original position, so the total distance we get is by adding
0.25m 4 times that is 1m.</span>
