I believe the correct answer is D.
Answer:
A: 43.55
Step-by-step explanation:
Place value can be defined as the numerical value representing a digit owing to its position in a number. Some examples of the various place values used in representing each digit are tenths, hundredths, thousandths, unit, tens, hundreds, thousands etc.
For example, in the number 43.55;
- The place value of 4 is tens.
- The place value of 3 is units.
- The place value of 5 is tenths.
- The place value of 5 is hundredths.
Rounding up to the nearest tenth simply means to have 1 significant figure after the decimal point.
Therefore, 43.55 to the nearest tenth is 43.6
Centripetal acceleration is given by:
g=v^2/r
where:
v=velocity
r=rate
But
V=200 m/s, g=9.8 m/s^2
plugging the values in the formula we obtain:
9.8=200^2/r
r=200^2/9.8
r=4081.63 m
The answer would be 2.4, or in fraction form 12/5. Please mark brainliest <3
