What multiplicative factor would you increase tension if you double the speed of a wave on a string?
The speed of the standing waves in a string will increase by about 1.414 (the square root of 2 to be more precise) if the tension on the string is doubled. The speed of propagation of the wave in the string is equal to the square root of the tension of the string divided by the linear mass of the string. That's the tension of the string divided by the linear mass of the string, and then the square root of that. If tension doubles, then the tension of the string divided by the linear mass of the string will double. The speed of the waves in the newly tensioned string will be the square root of twice what the tension divided by the linear mass was before. This will mean that the square root of two will be the amount the speed of the wave through the string increases compared to what it was. The square root of two is about 1.414 or so.
How can you lower the pitch of a note on a quitar by altering then tension of the string?
The pitch is determined by by the frequency in which the string is swinging, which, in turn, is determined by the speed with which a wave can travel through the string. The higher the tension in the string is, the easier it is for a wave to travel through it, and if the speed of the wave increase, so will the frequency, and by default the pitch of the note. And vice versa. If I remember my physics correctly :)
What does the length of a string on a guitar have to do with pitch?
Vibrations run up and down the string at the sound of speed. The longer the string the lower the frequency of the wave biting both ends, resulting in a lower pitch. Frequency is simply the frequency of the vibrations.
A 2 kg ball on a string is rotated about a circle of radius 10 m The maximum tension allowed in the string is 50 N What is the maximum speed of the ball?
15.8 m/s
A cello string 75m long has a 220-Hz fundamental frequency How do you find the wave speed along the vibrating string?
75 x 2 = 150 cm [wavelength = 2x part of string that it's vibrating] 150cm / 100 = 1.5m [convert to meters] 220s x 1.5m = 330m/s [speed] So in a way, your measuring is wrong due to the fact that you measured the whole string instead of the part that's vibrating after being plucked or bowed.
Does it take an increasing force to cause an increasing speed?
Yes. It is one of the laws of motion (the second law) that says that an object in motion will not change its motion unless acted on by and outside force. You'll have to add more foce to cause the object to speed up. Correction: No. The key word in the question is "increasing." A constant force will cause a constant rate of acceleration. Increasing force will cause an increasing rate of acceleration.
By increasing your speed you also increase?
Force of impact.
How is increasing speed acceleration?
By definition acceleration is the change in velocity (speed).
How does increasing the speed of an object change its momentums?
Increasing the speed of an object will increase its momentum as well (momentum=mass*velocity).
How will the speed and the slip of the motor change with increasing load in star wye and delta connection?
the speed decrease if increasing load..in star connection the speed lower
What is the string thing you pull down to change the speed of a ceiling fan?
The string activates a switch in the fan.
Why does mud attached with the wheel of a vehicle sprinkled away more if its speed increases?
An object moving in a straight line needs to have a force applied to it for it to change direction. A faster object requires a stronger force to change its direction by the same amount in the same amount of space as you did with the lower speed object. Imagine swinging a stone on the end of a piece of string around your head. The stone is moving in a circular motion and therefore it is always changing direction. The string is pulling the stone in a circular motion and is therefore acting as a force. Now the string can only take so much force so if you speed up the stone, the string has to apply more force to the stone in order for it to be changing direction all the time. Once the stone is going fast enough, the string will not be able to provide enough force and will break and the stone will fly off at a tangent. Think of the "stickiness" of the bits of mud as the string. As you speed up the wheel, the string (stickiness) breaks because it cannot provide enough force to keep the mud moving in a circle. If you're interested in this kind of stuff you should study mathematics which covers circular motion in the mechanics section
By increasing your speed you also increase force of impact. True or False?
True
What three things can acceleration mean?
Increasing speed, decreasing speed, and change of direction
Is the lever increase the force to move an object but it does not change the direction of the force?
There are 3 basic types of levers. 1st class, 2nd class and 3rd class. some change the direction of the force, some do not. some increase the force, some do not. A broom is an example of increasing speed, but not force. The direction of the effort (force you put in) and the resistance (force applied to the floor) is the same.
What happensto the speed of an object if a unbalanced force acts on it?
Then the speed will change.Then the speed will change.Then the speed will change.Then the speed will change.
