What is the equation used to find the speed of a wave?
Here is an equation that relates three quantities of any wave: speed = frequency x wavelength. However, I am pretty sure that usually, you'll have to somehow measure the speed of the wave, instead of calculating it. In other words, you would measure the speed and the frequency, and then use the formula to calculate the wavelength; or measure the speed and wavelength, and use the formula to calculate the frequency.
What is the speed of a sound wave that has a frequency of 250 Hz and a wavelength of 1.5m?
Use following equation [speed= wavelength*frequency] "Atul ashish"
How do you find acceleration when given only mass?
Acceleration is the change in velocity over time. Acceleration = change in velocity / time elapsed So, find the initial velocity of the mass (0 if starting from rest) and another velocity that occurs afterwards and find the difference. Then, divide the change in velocity by the time elapsed. If you know the mass of and the force acting on the object, you can use this formula: Force = mass x acceleration Substitute for your known variables and solve algebraically.
What units are used in average speed?
It is usually meters per second. But it can vary if that is not a suitable unit to use.
If you cycled 100 meters in 9 seconds What is the average speed?
You are supposed to use the definition of "average speed", and simply divide distance by time. The answer will be in meters/second. If you want to convert that to kilometers/hour, multiply the result by 3.6.
How do you find the wave speed with the wavelength and amplitude?
Not enough information. You can use the equation speed = frequency x wavelength, but in this case, you don't have enough data to calculate the speed.
What equation do you use to find the speed of a volleyball spike in mph?
I don't know how that could be determined mathematically, except in theory. Normally they use radar.
Why do you use average speed?
The concept of average speed is somewhat simpler than "instantaneous speed".
How can I Calculate average velocity without time?
Will you settle for average speed ?The general method for solving any problem is to use what you do know in orderto find the answer. Generally, you never use something you don't know, right ?Well, you told us what you don't have, but neglected to mention what you do have.If you know starting and ending speed, then average speed = 1/2 (starting speed + ending speed).If you know distance and acceleration, then time = sqrt( 2 x distance / acceleration).Then you have time and distance, and you can find average speed.

How do you find the speed of a projectile?
To find the average velocity of a projectile, use V = D/T (Velocity equals Displacement over Time).
Can you use average speed to calculate the speed of an object that is moving at a constant speed?
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.
What equation do you use to find ohms?
Use the equation that shows the relationship between ohms and the properties that are known.
What must be true of an equation before you can use the quadratic formula to find the solutions?
the formula you are going to use to answer the equation
How do you solve speed word problems?
Use the equation, speed = distance / time, substitute in the given information from the problem and solve it.
Can you find the value of X in 3 X 16 18 when the average is 11?
Use the definition of average, write the corresponding equation, and solve it. In this case, the equation is:(3 + x + 16 + 18) / 4 = 11 since there are four numbers.
What sre the measurements for average speed?
to measure the average speed of a car for instince you must use the following formula SPEED= distance divided by time
