Answer:
90m/s
Explanation:
Given parameters:
Acceleration = 10m/s²
Time of fall = 9s
Unknown:
Final velocity = ?
Solution:
We can assume that the cart falls from rest.
Initial velocity = 0m/s
Using
v = u + gt
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
t is the time
v = 0 + 10 x 9 = 90m/s
The center of an atom is called the nucleus.
Hope I helped!

The answer is d (electric magnetic fields)
The atomic nucleus is made up of a certain amount of protons(+ charge) and neutrons (0 charge). It is the center of an atom. The electrons (- charge) orbit the nucleus.
Hope this answers it.
