80 meters. Since the only force on the car is centripetal force then:
Fc = mac
ac = v2/r
Fc = (mv2)/r
Solve for r
r = (mv2)/Fc
r = (1200)(20)2/(6000)
r = 80m

What is the velocity in meters per second of a person at the equator due to the earths rotation?
At the equator the earth spins at 0.0005 Meters per second. Here's a bit more data -- you can do the math. ;-)
•How fast is the Earth spinning? 0.5 km/sec•How fast is the Earth revolving around the Sun? 30 km/sec •How fast is the Solar System moving around the Milky Way Galaxy? 250 km/sec •How fast is our Milky Way Galaxy moving in the Local Group of galaxies? 300 km/sec
The answer is incorrect. If you do the math, then the velocity would be 500m/sec.
.0005m/s equates to .0000005km/s.
What could be wrong with your clothes dryer if it no longer heats but just spins and blows cool air?
Often there are two fuses for an electric dryer. One of them is for the heating element, and the other is for the motors. Check both fuses. If they both are good, the heating element might be bad, or an internal circut breaker might need to be reset.
The metal foil is a resistor---it conducts electricity but also resists its flow somewhat. When the sheet is bent one way it stretches the foil slightly, making it longer and thinner. This raises its resistance, since the electricity has further to go and a more constricted path to follow. On the other hand, when the sheet is bent in the other direction it compresses the foil, making it shorter and wider and lowering the resistance. Because the foil strip is so long, even slight strains will cause fairly big changes in the resistance, which will be picked up by the Wheatstone bridge.
Rpms is revolutions per minute. How many times the engine turns a complete cycle. Torque is measured at the rear wheels(if were talking about a rear wheel drive car). Torque is the true power of an engine. If you have alot of horse power and low torque, the working power of the engine underload will be awful. The best way to measure and only true way is to Dyno the engine
Why does padding left in a canoe steer you right?
Because when you push the water, you are using the opposite force of the way that you want to go. Like on a rocket, the exhaust moves downward, but as a result, the rocket moves upward.
What is angular speed and angular velocity?
That is analogous to linear speed and velocity, but for rotation. Whereas a linear speed (or velocity) is expressed in meters per second (or some other units of distance / time), the angular speed or velocity is expressed in radians / second (or some other units of angle / time).
Of course, when something rotates, there is also a linear speed, but different parts of an object rotate at different linear speeds, whereas the angular speed is the same for all parts of a rotating object - at least, in the case of a solid object. For example: the Earth rotates at an angular speed of 1 full rotation / day. The linear speed at the equator is approximately 1667 km/hour; close to the poles, the linear speed is much less.
Why does a fan stop immediately when you put off the switch?
It does not. It continues to rotate - slowing down gradually.
What is the result of adding a displacement vector to an another displacement vector?
another displacement
the center of a whirlpool is spinning the fastest. the cube is in the center so its spinning equal or a lil slower than the water directly under it but the water neer the edge of the cup is spinning slower.....put something in the toilet, flush it and observe how it spins faster as it reaches the center...........use something that wont clog the toilet
How is the magnetic force like centripetal force?
If a charged particle moves in a magnetic field then Lorentz magnetic force acting will be perpendicular to its movement and so the particle will be taken along a curved path. Lorentz force will be towards the centre of the curved path. Any force facing towards the centre of the curved path is named as centre seeking or centripetal force.
What is a centrifugal force tachometer?
THis type of tachometre is also knowm as flyball tachometre. The basic principle of this tachometre is that the centrifugal force is directly proportional to the shaft speed . Two fly-balls whose weights are small are used in this tachometre and hence it is called flyball tachometre . These two balls are used in developing centrifugal force. In this case the spring is compressed as function of shaft speed. It is noted that one end of the spring is connected to the sleeve and moved smoothly on spindle . The position of the sleeve is indicated as the speed of rotating shaft. The motion of the sleeve is amplified and it indicates the speed with the help of a pointer on scale. This type of tachometer is also used for linear speed measurements , with necessary attachments mounted on the spindle . For obtaining speed over wide range , this type of tachometer uses multiple range units. A gear train is used between the fly balls to complete the change from one range to another range . The draw back ofthe tachometer is overspeed which seriously damage the instrument . This type of tachometers are widely used for measuring of shaft speeds upto 40×10^3 rpm . Its accaracy is + or - 1% of full scale.
Is angular momentum always parallel to angular acceleration?
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
Are centrifugal force and Reactive Centrifugal force the same thing?
Reactive centrifugal force is not the same thing as centrifugal force. Reactive centrifugal force is the reaction force. It is the reaction force reacting to a centripetal force.
What is multiple motion and give their example?
the object that can perform two or more types of motion at the same time is called
multiple motion.
What- Dexter designs a paddle fan.Which angle appears to be the angle of rotation in his design?
60 degrees
9 degrees
Can we stop the core of the Earth from spinning?
No. And even if we could, the spinning of the rest of the Earth will quickly make the core spin again.
Why infinitely small angular displacement vector?
I am not sure what situation you are talking about, but "infinitely small" amounts are basically used in calculus. Formally, "infinite small" amounts, or "infinitesimals" are avoided; rather, you investigate what happens when a certain amount gets smaller and smaller.As an example for such calculations, velocity is defined as dx/dt, meaning you divide a very small distance (the distance moved) by a very small time interval (the time elapsed) - and investigate what happens when dt (the time interval) becomes smaller and smaller ("tends toward zero", though it can't actually be zero itself, because then you would have a division by zero).
Basic answer is that when twisting two ropes together you are causing tension in the fibers of the ropes as they bend around each other. If you don't secure both ends of the two ropes the tension will pull the ropes back to their relaxed state. Think of stretching out and wrapping a rubber band around your finger.
The ISS completes each orbital revolution of the Earth in about 90 minutes.
360 degrees/90 minutes =
-- 4 degrees of angle per minute of time
-- 4 minutes of angle per second of time
-- pi/45 radians per minute
