How long would it take for me to pay these loans off while making about 50k a year with an interest rate of 10%? I have taken out subsidized and unsubsidized stafford loans.

If I have 115,000 dollars in debt, make 50k a year how long will it take for me to pay off my loans? What if I made 70k a year how long would it take for me to pay off my loans?

My parents are super hard core Protestant Christians. My dad is a pastor. I am dating a Catholic, but she believes that Jesus is the one and only way to be saved, which is what I believe as well. My parents are completely against dating her. They are threatening to cut me out of their lives. Yes. I disobeyed them and tried to hide the relationship from them at first and they found out. They are still very upset and are still threatening to cut me off from their relationship and even stop paying for my tuition in college. I love this girl and I don't ever want to break up with her, but I love my parents as well. My parents say that Catholics are not Christians and that I should not be yoked with unbelievers. What should I do in this situation? I am 21 years old and a junior in college. I have 3 more years of schooling left.

Suppose that you could pack neutrons (mass = 1.67 × 10 27̶ kg) inside a tennis ball (radius = 0.032 m) in the same way as neutrons and protons are packed together in the nucleus of an atom.

A) Approximately how many neutrons would fit inside the tennis ball?

B) A small object is placed 2.0 m from the center of the neutron packed tennis ball, and the tennis ball exerts a gravitational force on it. When the object is released, what is the magnitude of the acceleration that it experiences? Ignore the gravitational force exerted on the object by the earth

If the mass of a neutron is 1.67 x 10^ -27 kg, and the radius of a tennis ball is 0.032 meters, how many neutrons would fit inside the tennis ball if the neutrons are packed in a way that neutrons and protons are packed inside the nucleus of an atom?

In a CRT computer monitor, electrons approach the screen at 1.20 x 10^8 m/s. What is the de Broglie wavelength of these electrons? Note: the mass of electrons is 9.109 x 10^-31 kg; and use the relativistic momentum in your calculation.

A) 4.31 x 10^-12 m

B) 5.56 x 10^-12 m

C) 6.07 x 10^-12 m

D) 6.62 x 10^ -12 m

E) 7.85 x 10^-12 m

A woman is 1.6 m tall and has a mass of 55 kg. She moves past an observer with the direction of the motion parallel to her height. The observer measures her relativistic momentum to have a magnitude of 2.0 x 10^10 kg x m/s. What does the observer measure for her height?

A) Using the value 9.6 for f, and an n =1.5, compute the radius of curvature of a converging lens' surfaces using the lensmakers equation.

B) Taking f=R/2, compare this computed value of f with the value of 9.6 for f.

C) The index of refraction of the lens could have been a different value (n of glass varies generally from 1.5-1.7.) Would this make a difference?

Light is incident from air onto the surface of a liquid. The angle of incidence is 53 degrees, and the angle of refraction is 34 degrees. At what angle of incidence would the reflected light be 100% polarized?

A light bulb emits light uniformly in all directions. The average emitted power is 150.0 W. At a distance of 5 m from the bulb, determine (a) the average intensity of the light, (b) the rms value of the electric field, and (c) the peak value of the electric field.

I got A with .48 W/m^2, but I do not know how to get B and C. please let me know!

Which one of the following wavelengths is in the infrared range of the electromagnetic spectrum?

A) 100 mm

B) 100 nm

C) 400 m

D) 2 x 10 ^-15 m

E) 20 µm

One of my friends has a Youtube partner account called "TheAsianZing." Buffalo Wild Wings trademarked the name, "Asian Zing." If Buffalo Wild Wings were to see this Youtube channel, could they possibly sue him for it? Or would the "The" in front of his username be enough to prevent them from sueing him? He makes money from Youtube, but not much. Would he be better off just starting all over?

There are approximately 110 million TVs in the United States. Each uses, on average, 75 W of power and is turned on for 6.0 hours a day. If electrical energy costs $0.12 per kWh, how much money is spent every day in keeping the TVs turned on?

Sound emerges through a doorway, as in Figure 17.10. The width of the doorway is 77 cm, and the speed of sound is 343 m/s. Find the diffraction angle theta when the frequency of the sound is

a) 5.0 kHz

and

b) 5.0 x 10^2 Hz.

What are some differences between these? I would like to know from the perspective of different people

I'm thinking about taking a physics course that is self-taught with teaching ourselves everything with lab. However the teachers will be available for our help if we need them. Will non-calculus based physics II be too hard? Here is the syllabus from last year: http://users.stlcc.edu/cburkhardt/sum/info.pdf

Please let me know. Thanks!
