A solid bar of length L = 1.32 m has a mass m1 = 0.751 kg. The bar is fastened by a pivot at one end to a wall which is at an angle θ = 35.0 ° with respect to the horizontal. (in other words, the angle between the wall and the beam is 35 degrees).The bar...

A 13.2 kg crate is pulled by a 157 N force (parallel to the incline) up a rough incline. Assume that the incline makes an angle of 34.0° with the horizontal and that the coefficient of kinetic friction is 0.434. The crate has an initial speed of 1.53 m/s....

It takes 6.7 J of work to stretch a spring 4.4 cm from its unstressed (relaxed) length. How much work (in J) is needed to compress the spring an additional 3.8 cm? I found the spring potential energy to be 6.7 J, and the spring constant to be 6921.5. I th...

Solve for v: 62.7 = 3.65 v^2 + 0.0875 (v^2 / 0.09)

A spring stretches 5.00 cm when a 10.00 g object is hung from it. The object is replaced with another object of mass 20.00 g that oscillates in simple harmonic motion. a) Calculate the spring constant in N/m. Use 9.8 m/s2 for g. b) Calculate the period of...

The speed of a transverse wave on a string is 18 m/s when the tension is 3.0 N. What tension is required for the wave speed along the string to be 19 m/s? Answer in Newtons.

You place a piece of paper on a balance and find that its mass is 0.63 g. You add a lump of NaOH to the paper and get a mass of 22.21 g. You remember that you forgot to tare the balance before taking this measurement. You tare the balance, add another lum...

Draw a counter example that shows that the statement, "if a segment is parallel to one side of a triangle and intersects two other sides then it must be the midsegment of that triangle" is false. Please explain how i can prove this wrong! Thanks!

The segments formed by the altitude to the hypotenuse of a right triangle are 8 and 10. Find the shorter leg of that triangle. Help please! I am confused on which formula to use or if I should use the Pythagorean Theorem.

What can you do to deter identity theft? (A) share your personal information. (B) shred financial documents after you use them. (C) share your personal information on the phone. (D) throw away paperwork with personal information. D?

For tension in the cable, I did 7.51N (1.32/2) + 7.22 (1.32-0.775)= 9.25. Then I took that number and divided it by 1.32, which equals 7.01. I then divided 7.01 by sin(55 degrees), which gives me a Tension of 20.2.

The force of gravity is also 10 N/kg for this problem.

Thanks, it's much appreciated.

(x/0.76)+6.5 (x^2)*(56+3.42)

1 2/3 + 1/6 lets work with the mixed number first. 1 2/3 is equal to 5/3. now we have: 5/3 + 1/6 But their denominators arent the same! so, you multiply by 2 so that the 5/3 fraction can become sixths. so, 5x2/3x2 this becomes 10/6 so, now we have 2 frati...

Six more than two times a number

that's all that needs to be corrected? By the way, I don't have a keyboard or extention handy to add the accent marks

also, i missed one: No hay clases los jueves y los viernes

Thank you so much!!

yes i see that now thank you.

Thx Pancake!!
