Answer:

18m/s

Explanation:

Given parameters;

Initial velocity  = 10m/s

Acceleration  = 2m/s²

Time = 4s

Unknown:

Car's new velocity  = ?

Solution:

We use one of the kinematics equation to solve this problem:

          v  = u + at

v  = new velocity

u = initial velocity

a = acceleration

t = time

      v = 10 + (2 x 4)  = 18m/s

What is the radius of a hydrogen atom whose electron is bound by 0.544 ev? express your answer with the appropriate units?
insens350 [35]
First, we need to calculate the principal quantum number n for this electron, using the equation:
E = (-13.60 eV) / (n x n)
where E is the energy that is used to bound the electron (here, E = - 0.544 eV).
- 0.544 eV = (-13.60 eV) / (n x n)
n x n = (- 13.60 eV) / (- 0.544 eV)
n x n = 25
n = 5

The orbital radius that is equal to the radius of a hydrogen atom is calculated using the equation:
r = 0.053 nm x n x n
r = 0.053 nm x 5 x 5
r = 0.053 nm x 25
r = 1.325 nm
