Answer:
if you mean *responsible* for the transport of water from the roots to leaves is Xylem
Answer
given,
initial speed of the car = 90 m/s
final speed of the car = 0 m/s
distance taken to stop = 110 m
calculating the acceleration of the car = ?
using the equation of motion
v² - u² = 2 a s
0² - 90² = 2 x a x 100

a = 40.5 m/s²
acceleration of the formula one car is equal to a = 40.5 m/s²
Answer:
a) 3.00×10⁸ m/s
b) 2.9979×10⁸ m/s
c) 2.997925×10⁸ m/s
Explanation:
299792458 m/s is the speed of light
Let us write this in scientific notation first
2.99792458×10⁸ m/s
a) In three significant figures
We need to round the number to the hundredths place
3.00×10⁸ m/s
b) In five significant figures
We need to round the number to the ten thousandths place
2.9979×10⁸ m/s
c) In seven significant figures
We need to round the number to the millionths place
2.997925×10⁸ m/s
