What are airplane mach numbers?
Mach refers to the speed of sound. A plane that travels at Mach 2 means that it travels twice the speed of sound in air. The actual speed will vary a bit depending on the altitude.Mach number is a measure of relative speed. It is the speed of something relative to a medium, usually air, and divided by the speed of sound in that medium: : : is the Mach number : is the velocity of the object relative to the medium used and : is the velocity of sound in the medium Mach number is the number of times the speed of sound an object or a duct, or the fluid medium itself, move relative to each other. It is named afteran Austrian physicist Ernst Mach.
A fisherman travels downstream at full speed to?
The maximum speed that a vessel will achieve relative to ground is its own maximum speed through water plus the speed of the the moving water downstream.
8.0 m per s and a boat is traveling 10.0 m per s upstream what is the boats speed relative to the riverbank?
f a river current is 8.0 m/s, and a boat is traveling 10.0 m/s upstream, what is the boat's speed relative to the riverbank?
A motorboat maintained a constant speed of 24 miles per hour relative to the water going 35 miles upstream and then returning the total time for the trip was 3.0 hours What is the speed of current?
The current speed is about 4 miles per hour.
How fast in in Mach would you have to go to make it 442 miles in one minute?
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
What speed does have the earth?
Speed must be specified relative to something. Relative to the Sun, the speed of Earth is about 30 km/second. Relative to the Milky Way, or relative to the Local Group, you would get different numbers.
Why is mass not relative?
Mass IS relative to the speed you are going.
What is the relative speed of liquid particles?
No
How fast can a man on a train run?
the answer is relative.. if you are standing on the same train, for you the man will be running as fast as it would do on the ground. If you are standing on the ground, then his speed relative to you will be the composition of the train speed + his speed. to make it more interesting.. think now that the train it's running with a speed that approach the speed of light relative to you.
Is speed and distance the same thing?
No, distance and speed are two separate measurements. Distance is how far an object moves relative to speed and time, and speed is how fast an object moves relative to time and distance.
What effects the speed of a object?
Speed is relative to the speed of light and gravity. So gravity could effect speed.
Is speed relative to mass?
Speed is not directly relative to mass. An object's speed is determined by its velocity, which is a measure of both the speed and direction of its motion. While mass can affect an object's acceleration and how it responds to external forces, it does not directly determine its speed.
How time is relative to the speed?
They Both run... Get it!
What is an airspeed?
An airspeed is the speed at which an aircraft is travelling relative to the air through which it is flying.
What is relative wind speed?
Relative for starters means exact or close to. Wind Speed is how fast the air is blowing. It other words, this would mean an estimate or exact measurement to the Wind Speed.
Suppose you are riding in a car describe your motion relative tothe car the road and the sun?
Relative to the car you are motionless. Relative to the road you are moving at the speed of the car. Relative to the sun you are moving at the speed of Earth as it orbits the sun (30km a second).
Rocket A travels with speed 0.800c relative to the earth Rocket B passes rocket A with speed 0.500c relative to rocket A Determine the speed of rocket B relative to the earth Assume that the earth?
0.929c formula is: vbe =( vae +vba )/(1+( vae *vba )/c2 )
