How far will sound travel in 1 hour in miles per hour at 68 degrees?
"How far" is a distance question. "Miles per hour" is a measure of speed. Distance cannot be measured in units of speed.
What is a postion-time graph?
It is a graph with distance on one axis and time on the other. The distance is measured on graphed on "how far you currently are from a certain starting point", rather than "how fast you are travelling", or something similar...
How far is the distance if you have a 46 inch TV?
Your question is vague. If by "distance" you mean the diagonal length then on a 46" TV the diagonal length is 45.9". If you mean how far should you sit from a 46" TV then around 7 to 8 feet.
What can distance be measured?
Small distances such as the length of a pencil can be measured in inches, millimeters, and centimeters. Distances such as the height of you door or the length of a swimming pool are usually measured in feet, yards (customary units) meters, decameters or hecameters. (metric units) Then finally miles and kilometers which are usually used as how far you travel in a car. Hope this helped! ~ ClaireElaine
In what unit is velocity measured?
Velocity is the ratio of two fundamental physical quantities: distance and time, and iscomputed as the distance an object moves divided by the time in which it moves. InSI units distance is measured in meters, and time in seconds. Therefore in SI unitsvelocity is measured in meters/sec. However velocity can be measured in any unitsof distance per time: miles/hour, inches/year, micrometers/decade. As long as youhave a unit of distance in the numerator and a unit of time in the denominator youhave an acceptable unit for velocity.So far, to this point, what you have is the sizeof the velocity, also called "speed".To make a velocity out of a speed, you must indicate the direction of the speed.
