AI Thread Summary
An astronaut on Planet N-40 conducts an experiment using a 0.640 m pendulum to determine the planet's gravitational acceleration. Initially, she calculates the period of oscillation as 2.6 seconds for 10 oscillations but miscalculates the acceleration due to gravity. After receiving guidance, she correctly applies the formula g = (4π² * L) / T², leading to the accurate calculation of g. The discussion emphasizes the importance of correctly determining the period and using the appropriate formula for gravitational acceleration. Ultimately, the correct approach yields the desired results for the experiment.

Homework Statement



An astronaut has landed on Planet N-40 and conducts an experiment to determine the acceleration due to gravity on that planet. She uses a simple pendulum that is 0.640 m long and measures that 10 complete oscillations 26.0 s. What is the acceleration of gravity on Planet N-40?

Homework Equations



I am not sure what to use.

The Attempt at a Solution



I tried using T=2pi square root L/g and solve for g and plugged everything in. Period T I did 26/10 so 1 period every 2.6 seconds I got g=.595 and is non of the choices.

It is this formula above. I solved for g wrong. Now I got the correct answer thank you everyone.

There's a formula that you can use. Find the period and you should be able to solve for g.

Edit:
What formula did you get when you solved for g? I got a different answer.

When I caught my error I redid it and got g=(4pi^2 *L)/(T)^2
 
That should give you the correct answer.

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...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
