It depends on how hard the ball is one and so if its hard it might put a dent in the wall depending on how the ball is thrown at the wall and how hard the ball is and like any other way or big and small and other ways you have to pay attention on how hard it is, how hard you threw it, and how big it is

<h3>step 1. start with what is at the top of the list.</h3>
<h3>step 2. do 1 times 3 since it comes before division, and is in parentheses.</h3>
1 × 3 = 3
<h3>step 3. find 36 divided by 2</h3>
36 ÷ 2 = 18
<h3>step 4. add the values together</h3>
18 + 3 = 21
<h3>step 5. find 14 times 3</h3>
14 × 3 = 42 <em>you can also do 7 × 6 and will get the same result because 7 is half of 14 and 3 is half of 6</em>
<h3>step 6. add what is outside the parentheses</h3>
21 + 42 = 63
<h3>step 7. divide by 6</h3>
63 ÷ 6 = 10.5 
10 remainder of 3 <em>remainder means left over</em>

Speed = d/t
d = 200, t = 10
200/10 = 20
Solution: 20 m/s
Σ/ε
σ = F/A
ε = ΔL/L
F = force
A = area
L = lenght
ΔL = |old lenght - new lenght|
Answer:
Rutherford
Explanation:
In 1911, E. Rutherford and his collaborators bombarded a thin gold foil with alpha (positive) particles, coming from a radioactive material, at high speed. The experiment allowed observing the following behavior in the released particles: Most of them passed through the sheet without changing direction, as expected. Some deviated considerably e. A few particles bounced towards the emission source.
In the Rutherford Model the positive charge is concentrated in a central nucleus, so that the positive particles that pass very close to it, deviate enough from their initial trajectory and only those few that collide directly with the nucleus return in the direction of which they come from
.
The Rutherford Model states that: The atom has a central zone or nucleus where the total positive charge (that of the protons) and most of the mass of the atom, provided by the protons and neutrons. It also has an outer zone or cortex where electrons are found, which revolve around the nucleus. (Actually, the nucleus particles (protons and neutrons) were discovered after Rutherford established his model. Rutherford's experiment only reported a small, positive nucleus, did not clarify anything else)
