英语翻译 In physics terms,impulse tells you how much the momentum of an object will change when a force is applied for a certain amount of time . Say,for example,that you’re shooting pool.Instinctively,you know how hard to tap each ball to get the results you want.The 9 ball in the...
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 ...
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...
Terminal Velocity of a Human, Free Fall and Drag Force How to Understand Kinetic Energy, Momentum and Work Done How to Solve Projectile Motion Problems: Applying Newton's Equations of Motion to Ballistics Simple Machines: How Do Wheels and Axles Work?
This is essential.It's not adequate to be influenced by an impulse generating a fleeting moment of interest，and then you mistakenly think that this is your own interest where it lies in.这很重要，不能因为一时冲动，产生了瞬间的兴趣，便误以为这是自己的兴趣所在了。True interest involves a ...
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...
Performance of next-generation technologies combined with system-level insights enable a deeper understanding into the application and requirements necessary to solve these challenges.Vibration, one of the key components of machine diagnostics, has been reliably used to monitor the most critical...
Pendulums are systems of non-linear motion, which means there is a force, acting toward the pivot point, that keeps the pendulum moving in an arc. Because this force is perpendicular to the movement of the pendulum however, it does not affect the speed at which the pendulum moves....
As a college student, we are eager to positive rather than blind impulse, bold and not wantonly recklessly, dare to think and not utopian, deep into thinking and not like a dead end... Let's seize the youth and exercise ourselves here. Leave your hard figure in the organization activities...
