How Do You Solve for g in the Equation a = 1/(1+C) g sin θ?

AI Thread Summary
The equation a = 1/(1+C) g sin θ is discussed with a focus on rearranging it to solve for g. The initial attempt suggests g = (a + c)/sin θ, but there is confusion regarding the relationship between g and sin θ. Clarification reveals that the equation should be interpreted as a = (1/(1+C)) * g sin θ. The correct rearrangement leads to g = (a + aC)/sin θ. This highlights the importance of understanding the multiplication of g and sin θ in the equation.

1. The problem statement.


a = 1/(1+C) g sine pheta


Rearrange equation to solve for g.


My attempt of the solution is:


g = (a+c)/sine pheta

What confuses me is whether or not g sine pheta are all clumped together or if it's just g x sine pheta. Thanks!

Well gsinθ = g*sinθ

although I can't tell if your question is


a = \frac{1}{(1+C)g sin \theta} \ or \ a=\frac{1}{1+C}* gsin \theta
 
Ah, ok, thanks. It's the second one.

if so, then:


einsteinette said:

that's not correct,

<br /> \ a=\frac{1}{1+C}* gsin \theta

\ a{(1+C)}=gsin \theta
\ {(a+aC)}= gsin \theta
then
\ g=\frac{a+aC}{sin \theta}<br />
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
