Answer:
In my opinion, I think we do change when people come to our lives because the way we feel around people makes us feel a certain way around all people in our lives in a good way. They can change our lives by being there and helping us physically and mentally. We do have the choice to follow what someone is trying to change us. Example if we have a problem like addiction, we can choose to get help from anyone or choose not to. Traumas can affect us, but we need to seek help to not fear those problems anymore, thats why people who care about us really want us to change our way of health, addictions, and mental health. For me, as a child my dad was deported because he got a dui and decided for as punishment to be deported or to have a life sentence in the U.S. My mom suffered addiction to drugs and alcohol. I lived with my grandparents for almost my whole childhood untill the age of 9. Then my aunt got engaged and my new uncle decided to take us in because DC.S foound out that me and my other sibling weren't in school at all. Like we never attended school. So we were going to be seperated and taken for adoption untill my uncle had the heart to adopt us and here I am today. He gave us a better life because I finally experienced school,clothes, food, and a safer place to live. All the things I went through even abuse. He changed my life and we changed his. He cares about us, we helped him quit drinking, and that impacts him a lot to open up his heart and quit drinking.

Jane and her brother Matt look a little bit alike. Jane made a table. She wanted to figure out how she and Matt inherited certain traits.
Based on Jane's table, what can she say about their inherited traits?
Question 1 options:
A. Jane and Matt look like their mother.
B. Only a father can pass on the color of eyes.
C. Hair type is not passed down from parent to child.
D. Jan and Matt inherited eye color from their mother.
Traits are the expression of alleles combination in a genotype, and depend on the inherited alleles and the inheritance pattern. Option D. Jane can say that she and Matt inherited eye color from their mother.
How are traits inherited?Traits are the expression of the allelic combination in a genotype. The expressed phenotype will depend on the alleles inherited from each parent and the inheritance pattern.
According to the segregation principle, alleles separate during gamete formation. And during fertilization, two gametes from different parents merge to produce a zygote.
Each gamete carries one of the parental alleles. During fertilization occurs a combination of alleles that will express a phenotype.
Traits inheritance do not depend on each other, they are inherited by separate.
In the exposed example, eye color and hair type expression depend on the combination of the alleles in each genotype. And each trait is independently inherited from the other one.

A point charge q1=+5.00nC is at the fixed position x=0, y=0, z=0. You find that you must do 8.10×10−6J of work to bring a second point charge from infinity to the position x=+4.00cm, y=0, z=0. What is the value of the second charge?
The value of the second charge is 1.2 nC.

What percentage of the initial potential energy has been converted into heat instead of
kinetic energy?
The percentage of the initial potential energy that has been converted into heat is 18.07%.
Potential energy can be defined as the energy of a body due to its position in the gravitational field.
To calculate the percentage of the initial potential energy that has been converted into heat, we use the formula below.
Formula:
H(%) = [(P.E-K.E)/P.E]100............... Equation 1Where:
H = Energy converted to heatP.E = Potential energyK.E = Kinetic energy.But,
P.E = mgh........... Equation 2From the diagram,
m = mass = 0.5 kgh = 7 cm = 0.07 mg = 9.8 m/s²Substitute these values above into equation 2
P.E = (0.5×9.8×0.07) P.E = 0.343 JAlso From the diagram,
K.E = 0.281 J.Substitute these values into equation 1
H(%) = [(0.343-0.281)/0.343]100H(%) = 18.07%.Hence, the percentage of the initial potential energy that has been converted into heat is 18.07%.

a. What is the wheel's average angular acceleration?
b. What is the angular displacement of the flywheel during this acceleration?
c. If the flywheel has a mass of 155 kg and a radius of 0.650 m, what torque was required to accelerate it?
Thank you in advance.
(a) The wheel's average angular acceleration is 1.076 rad/s².
(b) The angular displacement of the flywheel during this acceleration is 17,455.6 rad.
(c) The torque required to accelerate the flywheel is 35.23 Nm.
Average angular acceleration of the flywheelThe average angular acceleration of the flywheel is calculated as follows;
[tex]\alpha = \frac{\Delta \omega}{t} \\\\\omega_f = 1850\frac{rev}{\min} \times \frac{2\pi \ rad}{1 \ rev} \times \frac{1\min}{60 \ s} = 193.76 \ rad/s\\\\\alpha = \frac{\omega _f - \omega_i}{t} \\\\\alpha = \frac{193.76 -0}{3\min\times 60 \ s} \\\\\alpha = 1.076 \ rad/s^2[/tex]
Angular displacementThe angular displacement of the flywheel during this acceleration is calculated as follows;

A gas at 110atm and 303K filled a container of 2L. If the temperature is raised to 353 K and the pressure is increased to 440atm, what is the new volume
Question 4 options:
5.8 L
0.58 L
58 L
10.6 L
Answer:
0.58 L
Explanation:
For this problem we need to simply use the ideal gas equation to create a proportional comparison for the initial information to the final information.
(P_1 * V_1) / T_1 = (P_2 * V_2) / T_2
Using this, we can solve for V_2 to find the new volume of the gas once pressure and temperature changes.
(P_1 * V_1) * T_2 / T_1 = (P_2 * V_2)
(P_1 * V_1) * T_2 / (T_1 * P_2) = V_2
Consider our givens:
P_1 = 110atm
T_1 = 303K
V_1 = 2L
P_2 = 440atm
T_2 = 353K
Now we simply plug in these values to the equation to find the new volume, V_2.
(P_1 * V_1) * T_2 / (T_1 * P_2) = V_2
(110atm * 2L) * 353K / (303K * 440atm) = V_2
77660 atm*L*K / 133320 K*atm = V_2
0.583 L = V_2
Hence, the new volume is 0.583 L.
