I have one and want to know its value! Thank you

I am looking into getting a Used F-250/F-350 lifted Truck. I am getting it more for want than need, I like these trucks alot and have always wanted a lifted jacked up truck. I won't be doing a lot of towing, I have jet skis but rarely will need to tow them. I don't really plan on needing to tow stuff all too often. So would it be smarter for me to get Gas truck or Diesel truck? Also, taking into consideration gas/diesel prices, with diesel now being more expensive compared to regular unleaded.

Determine the Mass of a Neutron Star that will collapse (Hypernova) into a black hole with a

Schwarzschild Radius of 7.4 x 108 m.

Calculate the length of a meter stick moving with a speed of v = 0.9995c as measured by an

observer at rest.

Velocity is still a distance over a time and no velocity can be greater than the speed of light

(c = 3.0 x 108m/s)

Find the radius to which the Sun must be compressed for it to become a black hole.

R= ? km

An astronaut travels to a distant star with a speed of 0.57 c relative to Earth. From the astronaut's point of view, the star is 6.8 ly from Earth. On the return trip, the astronaut travels with a speed of 0.95 c relative to Earth.

What is the distance covered on the return trip, as measured by the astronaut? Give your answer in light-years.

An astronaut travels to Mars with a speed of 8300m/s .

After 1 month (30.0 d) of travel, as measured by clocks on Earth, how much difference is there between the Earth clock and the spaceship clock? Give your answer in seconds.

Two strings that are fixed at each end are identical, except that one is 0.560cm longer than the other. Waves on these strings propagate with a speed of 35.2m/s, and the fundamental frequency of the shorter string is 212 Hz.

What beat frequency is produced if each string is vibrating with its fundamental frequency?

Does the beat frequency in part (a) increase or decrease if the longer string is increased in length?

epeat part (a), assuming that the longer string is 0.801cm longer than the shorter string.

The Shinkansen, the Japanese “bullet” train, runs at high speed from Tokyo to Nagoya. Riding on the

Shinkansen, you notice that the frequency of a crossing signal changes markedly as you pass the crossing. As you approach the crossing, the frequency you hear is f; as you recede from the crossing the frequency you hear is 2f/3. What is the speed of the train?

On January 1, 2011, the Mills Conveying Equipment Company began construction of a building to be used as its office headquarters. The building was completed on June 30, 2012. Expenditures on the project, mainly payments to subcontractors, were as follows:

January 3, 2011 $500,000

March 31, 2011 400,000

September 30, 2011 600,000

Accumulated Expenditures at December 31, 2011 $1,500,000

(before interest capitalization)

January 31, 2012 $600,000

April 30, 2012 300,000

On January 2, 2011, the company obtained a $1,000,000 construction loan with an 8% interest rate. The loan was outstanding during the entire construction period. The company’s other interest-bearing debt included two long-term notes of $2,000,000 and $4,000,000 with interest rates of 6% and 12%, respectively. Both notes were outstanding during the entire construction period.

A. Calculate the weighted average accumulated expenditures for 2011.

B. How much interest will be capitalized in 2011?

C. Make the journal entry (or entries) to record the interest expense and the capitalized interest for 2011. Record the interest as a liability using the Interest Payable account.

A mass oscillates on a spring with a period T and an amplitude 0.48 cm. The mass is at the equilibrium position x = 0 at t = 0, and is moving in the positive direction.

a. Where is the mass at the time t = T/8?

b. Where is the mass at the time t = T/4?

c. Where is the mass at the time t = T/2?

d. Where is the mass at the time t = 3T/4?

A block of mass = 4.00kg is attached to the end of an ideal spring. Due to the weight of the block, the block remains at rest when the spring is stretched a distance h= 5.00cm from its equilibrium length. The spring has an unknown spring constant k. Take the acceleration due to gravity to be g= 9.81 m/s^2.

What is the spring constant K?

Suppose that the block gets bumped and undergoes a small vertical displacement. Find the resulting angular frequency "w" of the block's oscillations about its equilibrium position. Need in radians/s
