For this, we need the formula:
V = k q / r
where k is the Coulombs law constant = 9 x 10^9 N
q is the charge of the hydrogen nucleus (proton) = <span>1.6 x 10^-19 C</span> 
r is the distance
Simply plug in the values and solve for V

Answer:

Electric potential, V = 19.2 volts

Explanation:

In this case we need to find the electric potential due to the nucleus of hydrogen at a distance of 7.5\times 10^{-11}\ m. For this we must know the concept of electric potential. It is the work done in moving a charged particle in electric field from zero to a particular point. Its formula is given by :

V=\dfrac{kq}{r}

q is the charge of nucleus of hydrogen i.e. proton

V=\dfrac{9\times 10^9\times 1.6\times 10^{-19}}{7.5\times 10^{-11}}

V=19.2\ \text{volt}

So, the electric potential due to the nucleus of hydrogen at a given distance is 19.2 volts. Hence, this is the required solution.

What is the acceleration during the pushing-off phase, in m/27 Express your answer in meters per second squared. A bush baby, an
Sindrei [870]

Answer:

a = 12.78 g's

Explanation:

Height reached by the object after push off is given as

H = 2.3 m

v_f^2 - v_i^2 = 2 a s

now we have

0 - v^2 = 2(-9.81)(2.3)

v = 6.72 m/s

now we know that this push last for total distance of 0.18 m

so during the push we will have

v_f^2 - v_i^2 = 2 a d

6.72^2 - 0 = 2a(0.18)

a = 125.35 m/s^2

now in terms of g = 9.81 m/s/s we have

a = \frac{125.35}{9.81} gs

a = 12.78 g's
