AI Thread Summary
To calculate the speed and time period of a satellite orbiting Earth at 600 km, one must first determine the total distance from the center of the Earth, which is the Earth's radius (6400 km) plus the satellite's height (600 km), totaling 7000 km. The gravitational force acting on the satellite at this height is crucial for finding its acceleration and angular speed. The confusion arises from incorrect unit handling and the misunderstanding of the relationship between time, distance, and velocity. Proper calculations involve using the gravitational pull to derive the satellite's orbital speed and time period. Accurate understanding of these concepts is essential for solving the problem effectively.

Homework Statement


A satellite is revolving round the Earth at a height of 600 Km. Find the speed of the
satellite and the time period of the satellite, if the radius of the Earth is 6400 km, and
mass of the Earth = 6*10^24 kg.


Homework Equations





The Attempt at a Solution



Well this is what i thought of till now...
we need to work out the time it takes to get round the earth..

6400/600 = 10.6666 (recurring). so 10 hours?...opps

another look
velocity = distance /time...

is time = timeperiod... I'm confused .. lol help please

Why are you dividing the radius of the Earth by the height of the satelite? Did you even think about what units you have?

What is the distance of the satellite from the center of the earth? What is the gravitational pull on the satellite at that height? What is the acceleration due to that pull? What angular speed does that correspond to?
 
distance between satellite and Earth is 600m... umm center of the Earth is not given prbly 6400/2? tht's the question given... nothin else i mean abt gravitational pull , angular speed etc.
 

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 '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}...
