The centripetal acceleration of the race car is 40500 mi/hr^2.
This can be calculated as the square of the velocity v divided by the radius r of the circular track:
a = v^2 / r
Substituting the given values of velocity v = 135 mi/hr and radius r = 0.450 miles, the centripetal acceleration a of the car is therefore
a = (135 miles/hour)^2 / (0.450 miles)
= 40500 miles/hour^2.
The two numbers would be 12 and 18.
Answer:
Seaweeds do not have seeds as land plants do. They can reproduce themselves by simply breaking apart, or they can release eggs and sperms to make spores, tiny one-celled capsules that can float away and grow into seaweeds by themselves.
Seaweeds also do not have flowers.
