How Newton's Laws apply to this situation: a mass suspended from two strings? How calculate the energy when I have force, time, and velocity given? Is a Ferris wheel an example of tension force? How to solve pendulum physics problems ...
For one thing, the explanation only accounts for telepathy, not clairvoyance or precognition. Presumably, if the information transfer occurs as electromagnetic energy, it has to be sent by someone; it has to travel from mind to mind. It doesn't explain how information would move through time ...
To pull off ignition and expansion in the 0.001 seconds before the pressurized air shoots out the exhaust, scramjets typically use hydrogen fuel, which has a high specific impulse (change in momentum per unit mass of propellant), ignites over a wide range of fuel/air ratios and releases a ...
To determine if your personality and abilities are suitable for a certainjob or major, I suggest paying attention to the lifestyle and work environment of those in the industry, as well as the different professional perspectivesof both outstanding and average professionals. Additionally, keeping up ...
we have a four-dimensional augmentation of the search space for every additional impulse. In order to minimize the cost function, the point at whichptakes its maximum value is usually taken as an initial iterate [45]. This approach leads to a direct method, a multivariate search problem, tha...
Thanks for the help but can you explain how to solve it... According to Physics Forums policy, you will need to make some attempt at solving the problem yourself first. Surely there is something in your class lecture notes or textbook that is relevant. Make an attempt to share what you...
To quantify how much protection was provided by each screen, the RMS pressure for the late part of the impulse responses (starting from 6ms after the direct sound) with and without the screen were compared. This is expressed as an attenuation value in dB, where the greater the attenuation ...

Newton’s equations allow you to look at these two aspects separately: “the baseball is moving forward at 90 mph but it’s also moving up and down like so under the influence of gravity”. For many people, that’s how physics goes. You can just solve each dimension (forward and vertic...
How do you set up the equation to find the final velocity of an object sliding down a rough incline if it has an initial velocity due to a spring pushing it and it has gravitational potential energy? Describe how to solve for the k...
