what are the force equations? i have no idea.

but then if i write separate force equations and solve together the acceleration would be the same for each mass wouldn't it? but it says to find acceleration of each mass. I am really confused :?

Homework Statement Three objects are connected on the table as shown in Figure P5.46 (a block of mass 1kg on a table is connected by two strings. The ends of the string each have a block hanging from it off the table, one of mass 4kg and one of mass 2kg. The strings are attached to a pulley...

isnt that what i did (given in the attempted solution)?

i don't get what you mean. How do u do the question?

ok thanks. teacher is a douche

another another more challenging log question. :( Homework Statement log6(5y − 5) = 4x^2 + 7 Homework Equations - The Attempt at a Solution 6( x^2 + 6x+5 ) +1

Homework Statement Combine into one log log√x + 1 + ( 9log x ) Homework Equations - The Attempt at a Solution I tried converting log√x + 1 to log(x+1)^(1/2)

Homework Statement Simplify log21/8 Homework Equations - The Attempt at a Solution the answer i got was -3 but it is not right.

no they did not. they told us to work it out using max and min slope method. The only thing close to working out uncertainty is that current is measured in mA.

Homework Statement The graph below shows the potential (V) applied to, and the current I(mA) drawn by, an electrical circuit. Use the max and min slope method to determine the: a) equation of line of best fit of the graph below (answer must be and equation relating to V and I). Your answers...

Hi thanks for replying. So gravity is acceleration hence it would be L/T^2. But how can the left side match the right side because the right side has so many different dimensions like M(mass), length (L^2), and also what are the dimensions of rho?

Hi salad samurai. I know about the dimension of v but however i have no clue of the dimensions of all the other variables like m, g, D, rho, and A

Homework Statement The terminal velocity of a mass m, moving at 'high speeds' through a fluid of density ρ(kg m^-3), is given by v = sqrt(2mg/DρA) where A is the cross sectional area of the object (m^2) and D a dimensionless "drag coefficient". i) Show that equation is dimensionally...

Hey jazrad thanks but I am still stuck. I've looked at page 7 and 8 but it only shows dimensions for velocity and acceleration. I've still got a lot of unknowns like D, A, m and ρ. I tried subbing in L/T for v and L/T^2 for g but I am still left stuck. Please give some more help although you...
