How do the 3 laws of moition and law of gravitation relate to the law of conservation of energy and momentum? y=kx, calculate the value of k when y = 12 and x = 8. Determine the potential energy of a 25 kg crate that was dragged 1.0 m up a 30 degree ramp. If the coefficient...
When is gravitation potential energy less than 0? Suppose an astronaut is moving relative to the Earth at a significant fraction of the speed of light. (a) Does he observe the rate of his clocks to have slowed? (b) What change in...
These separate forms of energy are not conserved, but the total amount of energy is conserved. If you drop a baseball from your roof, the ball has kinetic energy the moment it starts to move. Just before you dropped the ball, it had only potential energy. As the ball moves, the ...
2. If you calculate the cross products AxB and BxA, how will the results compare? They will be exactly the same. They will have the same magnitude, but different directions. They will have different magnitudes, but the same direction. They will have different magnitudes and directions. Only...
In summary, the conversation discusses how to calculate the location of a satellite in its orbit after a velocity increase, as part of a Hohmann transfer. The formulas for energy, speed, radius, and angular momentum are mentioned, and the process for determining the orbit parameters is ...
So now we can calculate the number of ounces in a gallon. 8 fl oz/c x 2 c/pt x 2 pt/qt x 4 qt/gallon = 128 fl oz/gallon Test Your Knowledge (fill in the blanks) 1. There are ___ fluid ounces in a US gallon. 2. The United States uses the ___ system of measuremen...
For example, his equations form the basis of modern electrical engineering, as they are used to calculate electric and magnetic fields. In addition, the technology we use today, such as cell phones, radios, and televisions, is based on Maxwell's equations....
But you can't just weigh something the size of a galaxy – you have to find its mass by other methods. One method is to measure the light intensity, or luminosity. The more luminous a galaxy, the more mass it possesses. Another approach is to calculate the rotation of a galaxy's ...
properly underdstand what is going on in this equation, I need to study four vectors (which is where \mu comes in), and also, how to calculate the gradient of an interval, and that to study these properly, I am well advised to begin with the simplest equations for the potential ...
[Thus] it is possible to calculate the thermal equilibrium state by finding the probability of the different possible states of the system. The initial state will in most cases be highly improbable but from it the system will always rapidly approach a more probable state u...
