    Satellite Speed
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.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
