    Density Ratio
AI Thread Summary
To calculate the density ratio of a newly discovered giant planet compared to Earth, the planet's average radius is 13 times that of Earth, and its mass is 963 times greater. The volume of the new planet can be determined using the formula for the volume of a sphere, leading to a density calculation. The user attempts to compute the density using the mass and volume but encounters errors in their calculations. The final density of the new planet is compared to Earth's density, which is approximately 5515 kg/m³. Accurate calculations are essential for determining the correct density ratio.

A newly discovered giant planet has an average radius 13 times that of the Earth and a mass 963 times that of the Earth. Calculate the ration of the new planet's density to the Earth's density.
 
Physics news on Phys.org
Find the volume of the new planet and hence its density, then divide that by the density of the Earth (you won't even need to do that numerically).
 
ok so this is what i did, 5.942x10^24 kg X 963/(169PI) = density that right?
 
i got 1.077760735e 25
 
still getting it wrong but now i have the density of the new planet as 2.663709251E17/ density of Earth 5515E3? (right?)
 

Thread 'Rolling without slipping on a curved surface'

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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
