What tangential speed v must the bob have so that it moves in a horizontal circle with the string always making an angle θ from the vertical?
To maintain a horizontal circular motion while the string makes an angle θ with the vertical, the bob must have a tangential speed ( v ) that can be determined using the relationship between gravitational force and the tension in the string. The vertical component of the tension must balance the weight of the bob, while the horizontal component provides the centripetal force required for circular motion. The formula for the tangential speed ( v ) can be expressed as ( v = \sqrt{g \cdot \tan(\theta) \cdot L} ), where ( g ) is the acceleration due to gravity and ( L ) is the length of the string.
What is the Weld penetration formula?
The weld penetration formula typically refers to the calculation of the depth of fusion achieved during welding, which can be influenced by various factors such as welding current, speed, and electrode type. A common empirical formula used for estimating weld penetration is: [ P = K \cdot I^n \cdot V^m ] where ( P ) is the penetration depth, ( I ) is the welding current, ( V ) is the welding speed, and ( K, n, ) and ( m ) are constants determined through experimentation. This formula highlights the relationship between the welding parameters and the resulting weld penetration.
Is there an optimal angle to throw a javelin?
Throwing a javelin at the optimal angle. Throwing a javeline at the optimal angle is throwing a javelin at the angle which the air flows efficiently around the javeline.The center of pressure is the aerodynamic force of drag and lift on the javelin.before the 1986 change in javelins , some of the best throwers in the world would throw the javelin with as little as 30 degree angle but greater speed because they were able to hold onto the javelin for longer , producing more force . Good throwers still use this method but the most commen method is releasing the javelin at about a 40 degree angles,causing a longer flight for the javelin.
How long did it take for the flag to rotate once in a full circle?
The time it takes for a flag to rotate once in a full circle depends on the speed of rotation. If the flag rotates at a constant speed, the time can be calculated using the formula: time = 1 / rotational speed. For example, if the flag takes 10 seconds to complete one full rotation, the rotational speed is 1 rotation per 10 seconds, so the time taken for one full rotation is 10 seconds.
How do you calculate echolocation?
Echolocation is calculated by measuring the time it takes for sound waves to travel from the emitter to an object and back. This involves sending out a sound pulse, then recording the time until the echo returns. The distance to the object can be calculated using the formula: Distance = (Speed of Sound × Time) / 2, where the speed of sound in air is approximately 343 meters per second at room temperature. The division by two accounts for the round trip of the sound wave.
What is the angle of rainfall on a moving car?
That's a function of wind speed and direction, car speed and direction, and the downward velocity of the rain drops.
How do you calculate the turning radius of a car?
I don't recall the exact formula, but, it involves the car's speed and the car's tires slip angle at a given speed.
What is the formula to calculate the average angular speed of an object rotating around a fixed axis?
The formula to calculate the average angular speed of an object rotating around a fixed axis is: Average Angular Speed (Change in Angle) / (Change in Time)
What is the average angular speed formula and how is it calculated?
The average angular speed formula is: Average Angular Speed (Change in Angle) / (Change in Time) It is calculated by dividing the change in angle (measured in radians) by the change in time (measured in seconds). This gives the average rate at which an object rotates or moves in a circular path over a certain period of time.
Are hurricanes classified by their rainfall amount or there wind speed?
rainfall
What is the formula for a triangle and for speed?
In the case of a triangle, it depends on what the formula is for: the area, an angle, the length of a side, the radius of an inscribing circle or whatever. And in both cases, the answer depends on what information is available.
Formula for speed?
The formula to determine speed is Speed= wavelength*frequency
What is the formula in getting the maximum speed?
The formula to calculate maximum speed is: maximum speed = square root of (2 * acceleration * distance). This formula takes into account the acceleration and distance traveled to determine the maximum velocity attainable.
Why is knowing the sound of speed important?
just incase someone is getting hurt you can use a formula to find there location
What is the formula for finding speed?
what is the formula for speed what is the formula for speed
What should you do when operation a boat in large waves and high wind?
head into the waves at a slight angle and reduce speed
How long does it take to drive 107 miles?
That depends on the speed. Use the formula distance = speed x time.That depends on the speed. Use the formula distance = speed x time.That depends on the speed. Use the formula distance = speed x time.That depends on the speed. Use the formula distance = speed x time.
