How does the oscillation frequency compare when being horizontal and when being on an inclined plane (assuming frictionless). I thought this: When on Horizontal surface frequency = angular frequency (w) / 2∏ Since frequency does not depend on acceleration, the frequency would remain...

Homework Statement Two balls of equal mass m undergo a collision, the velocities of the balls make angles of 25.5° and -45.9° relative to the original direction of motion of the moving ball. (a) Draw and label a diagram to show the balls before and after the collision. Label the angles...

Homework Statement A 55 kg student stands on a 4.6 kg surfboard moving at 2.0 m/s [E]. The student then walks with a velocity of 1.9 m/s [E] relative to the surfboard, relative to the water. Neglect Friction. Answer: 0.25 m/s[E] Homework Equations m1vi1 + m2vi2 = m1vf1 + m2vf2 The...

Homework Statement A 35 kg child is jumping on a pogo stick. If the spring has a constant of 4945 N/m and it is compressed 25 cm, how high will the child bounce? Answer: 0.45 m Need help substituting the right variable. Homework Equations ETi= ETf Egi + Eki + Eei = Egf + Ekf + Eef...

Thank you very much! The square-root was getting to me :) lol.

[SIZE="4"]Homework Statement Re-arrange the equation Fc=4π²mrf² to solve for frequency (f). State the relationship between frequency and (radius, mass, Fc). Homework Equations Fc=4π²mrf² The Attempt at a Solution Fc=4π²mrf² \frac{Fc}{4π²mr} = f² \sqrt{\frac{Fc}{4π²mr}} = f...

Homework Statement Hi I'm doing a physics lab about uniform circular motion to measure frequency and to compare it to mass,radius and force tension. (A & B) I did (C,D, E) I need help (a) What variables are being measured / manipulated in this lab? What type of relationship is being...

Determine the exact value of... (Square Root of Square Root) I was looking through my textbook and saw a interesting question, I attempted but couldn't get it. (The Answer in Back of Text Book Was Different From Mine..) Question Determine the exact value of... √10+√10+√10... I...

Question: Ryan is trying to hit a golf ball over a tree that is 18m above the ground. The height of the ball is modeled by the function h(t)= -5t2 + 20t, where t is the time in seconds. Explain the domain and range of the function. Will the ball go over the tree? This is grade 11 review and I...

Instrument used: -Meter Stick -Resonant Apparatus (closed air column) -1024Hz tuning Fork We got a closed air colum (provided by teacher), and we strung the 1024 hz tuning fork with a mallet close to the air column, we pulled the 'plunger' inside the closed air column to find the FIRST resonant...

The percent margin was 10%, and yes 2 sig digs were used for all measurements. Though the mathematical view to this lab is not such a deal. I am trying to think of possible sources of error that may have been done during the experiment to prevent my getting my 'desired value'

yes the teacher said these results are fine, now I need to find a possible source of error that may have 'decreased' the speed Also could a change in temperature may have affected the speed of sound? (even though I did not need temp. to find the experimental speed)?[the percentage error...

I know that temperature effects the speed of sound. Can this also effect the speed of sound? -Frequency : high or low? -Gas type : if its traveling through oxygen or helium ? How would they compare? Does their mass play a part and heat capacity? My attempt: I think the gas type will...
