Answer:
x = 0.081 m.
Explanation:
a) To find how much does the atmospheric pressure cause the spring to compress we need to use the following equation:
(1)
<u>Where</u>:
F: is the force
k: is the spring constant = 3300 N/m
x: is the distance of compression =?
The force can be found as follows:
<u>Where</u>:
P: is the atmospheric pressure = 101325 Pa
A: is the area of the piston = πr²
r: is the radius = 0.029 m
Now, from equation (1) we can find x:
Therefore, the atmospheric pressure causes the spring to compress 0.081 m.

B, is older
Because if you look on the scale b is deeper
Answer:
a The velocity of the third particle is 
b The total kinetic energy increase 
Explanation:
To solve this question we are going to be using the concept of conservation of momentum which is mathematically represented as
From the question
Mass of unstable atomic nucleus 
Mass of x-axis particle 
Velocity of x-axis particle 
Mass of y-axis particle 
Velocity of y-axis particle 
Since the initial mass is known we can obtain the mass of the third particle
Using the conservation of mass mathematical expression
Using the mathematical expression above for conservation of momentum
The above is the vector solution now to obtain the value in numeric form we evaluate the magnitude of the vector
To obtain the total increase in kinetic energy which is mathematically represented as
![E =\frac{1}{2} [(5.20*10^{-27})(6.0*0^{6})^2 + (8.44*10^{-27})(4.00*10^6)^2+\\\\(2.16*10^{-27})(21.285*10^6)^2]](https://tex.z-dn.net/?f=E%20%3D%5Cfrac%7B1%7D%7B2%7D%20%5B%285.20%2A10%5E%7B-27%7D%29%286.0%2A0%5E%7B6%7D%29%5E2%20%2B%20%288.44%2A10%5E%7B-27%7D%29%284.00%2A10%5E6%29%5E2%2B%5C%5C%5C%5C%282.16%2A10%5E%7B-27%7D%29%2821.285%2A10%5E6%29%5E2%5D)
Increases
Explanation:
Energy increases the speed of the particles in a substance. When energy is added to a substance they gain more kinetic to move.
- When energy is added to solid, the particles begins to vibrate about their fixed point.
- They reach a point where they break lose and the ordered structure of a typical solid collapses.
- They begin to move about freely and flow as in a liquid.
- When enough energy is added, they break their intermolecular attractions and becomes gaseous.
- An increase in energy increases the kinetic energy of the particles of a substance.
- The reverse is the case when energy is removed.
