1.) a student moves a box of books down the hall by pulling on a rope attached to a box up a ramp. the student pulls with a force of 185n at an angle of 25° above the horizontal. the box has a mass of 35kg, and the coefficient of kinetic friction between the box and the floor is 0.27. find the acceleration of the box. 2.) the student in item 1 above moves the box up a ramp inclined at 12° with the horizontal. if the box starts from rest at the bottom of the ramp and is pulled at an angle of 25° with respect to the incline and with the same 185n force, what is the acceleration up the ramp?

For the problems presented, the answer would be the following:

1. Givens are:

Θ – 25 degrees

µ = 0.27 

g = acceleration due to gravity = 9.8 m/sec^2

Answer would be a = 2.14 m/sec^2.

2. Givens are:

N = 257.32 newtons 

f = 0.27(257.32) 

f = 69.48 N 

Answer would be a = 2.80 m/sec^2 

I am hoping that these answers have satisfied your queries about these specific questions.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
