Has there ever been any bridge that has survived a earthquake?
Many bridges survive earthquakes. Most earthquakes are small or moderate and do very little damage.
When did the first International Earth Day occur?
no one knows this means never ever ever ever ever never
When can forces be added together?
forces can be added only when they both are going in the same direction as 2n + 2n = 4n of force in the same direction if they are 2 facing forces they would have had to be subtracted, which ever force is greater that will be the momentum of the force
What would happen if the gravitational pull on an object is greater than the buant force on a fluid?
As worded, the question doesn't mean much. I think you want to compare thegravitational force on an object with the buoyant force on the same object whenit's in a fluid.As long as the gravitational force is greater than the buoyant force, the objectmust keep accelerating downward ... sinking further and faster, and displacingmore fluid as it goes. If it ever displaces enough fluid for the buoyant force toequal the gravitational force on it (its 'weight'), then it stops sinking, and floatsright there.
When was For Ever Mozart created?
For Ever Mozart was created in 1996.
Why is during a trip a car instantaneous speed can ever be greater than its average speed?
Please ask that more clearly.
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
Does the instantaneous speed ever equal the magnitude of its average velocity?
Yes. For a start, this happens when the object moves at a constant velocity. Also, if moving in a straight line, even if the object changes speed there must needs be a moment when its instantaneous speed is equal to its average speed - since it cannot change speed suddenly, it must do so gradually.
Explain whether during a trips cars instantaneous speed can ever be greater than its average speed?
Of course it can.If you live 10 miles from your job, and you hit 100 miles per hour on the way to the office,but stop for coffee for an hour during the trip, I guarantee your average speed is less than100 mph.
Can instantaneous speed and average speed ever be different for a moving object?
Of course. When you're driving on the Interstate and you see a State Police cruiser coming up behind you, you stomp the brake and slow way down to the speed limit. Now your instantaneous speed is only the speed limit. You feel like you're crawling, you can't stand it, and as soon as you're sure he can't see you and doesn't care, you let your car come back up to normal speed again. Your average speed for the trip, or for any whole hour that includes that little episode, is comfortably in excess of the limit, although your instantaneous speed at any instant during those few minutes was exactly the posted limit.
Can an items velocity ever be greater than it's speed?
The velocity of an object cannot ever be greater than its speed as the two are directly linked. Velocity is very similar to speed except that it also takes direction into consideration.
Can the average speed ever exceed the maximum speed for a trip?
No, the average speed will always be between the minimum and maximum speeds.
What is the difference between average speed and top speed?
Average speed is a value of all the speeds you have travelled at over a certain length of time. Top speed is the absolute highest or fastest speed that you have ever reached. (A one time speed value).
How can instantaneous current values be determined?
Voltage divided by the resistance of what ever you want to measure the current in.
When you are describing the rate that a race car goes around a track should you use the term speed or velocity to describe the motion?
Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.Examples:80 km/h is a speed.80 km/h due north is a velocity.
What is the Average speed of 10 meters in 6 seconds?
Average speed is total distance divided by total time. Hence 10 metres in 6 seconds is an average speed of (10/6) = 2.66666 m/s. Notice the units of speed - if you ever forget that speed is distance over time, just remember speed's units is something like metres per second, miles per hour etc. "per" means divided by.
What is the fastest recorded speed ever on skeleton?
the fastest speed ever is 12874.97 mph
