An ion in a mass spectrometer follows a semicircular path of radius 15.2 cm What is the magnitude of the displacement?
Kutcho
The magnitude of the displacement of an object that has traveled in a semicircle (a half circle) is not the DISTANCE that it traveled, but the shortest distance between it's starting point and it's ending point. This means that the diameter of the semicircle = the displacement, so 15.2*2=30.4 cm is the answer.

Why is angular displacement a vector quantity?
Angular displacement is a vector quantity because it has both magnitude and direction. The direction of angular displacement is determined by the axis of rotation and follows the right-hand rule, while the magnitude is given by the angle of rotation. As a vector, angular displacement can be added, subtracted, and resolved into components, making it useful in calculations that involve rotational motion.
Why is displacement directly proportional to acceleration?
Acceleration is given by the equation v-u/t, whereby v is the final velocity of a body, u is the initial velocity and t is the time. So for there to be acceleration, there has to be a change in initial velocity (the starting speed of the body) and the final velocity of the body or if there is no change it would be 0/t and hence the acceleration will be 0. And we know that with a change in speed there has to be a change in displacement i.e. s=d/t. So to sum all this up with an increase in acceleration there is an increase in distance. But this is a very tricky question because you asked about displacement and since displacement is a vector quantity, it has both magnitude and direction. So if a body accelerates forward, then its acceleration is directly proportional to its displacement. However, if the body stops and starts accelerating backwards, it becomes a whole new different story. Given that displacement has direction, if the body moves backwards, then the displacement will be negative, but the acceleration positive. So displacement is directly proportional to acceleration ONLY when a body is moving forwards, but displacement is indirectly proportional to acceleration when a body is moving backwards from it's point of rest. But for distance, given that it is a scalar quantity, it only has magnitude so it is not affected by the direction of movement of the body. So distance is directly proportional to acceleration when a body is moving both forwards and backwards.
How would you differentiate between speed and velocity?
Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).

Out of momentum work volume and displacement which is the vector quantity?
The vector quantity among these is momentum. It has direction, and the others do not. A link follows and can be found below. Note that displacement could be a vector quantity, depending on its application.
Why component of vector is not greater than magnitude?
In two dimensions (to keep it simple), the magnitude is the square root of (x2 + y2). This follows directly from Pythagoras' Law. Now, experiment a bit with this formula, inserting some numbers, to get a feel for how the magnitude depends on the components. Pythagoras' Law can be extended to 3 or more dimensions in an analogous fashion.
If the acceleration of a particle is constant in magnitude but not in direction what type of path the particle follows?
You are mad 😂😂 you don't know this much easy answer 😆😆
Want is the aim of hookes law?
Hooke's law was designed to determine the restoring force of a spring, given its spring constant and the displacement of the spring from its equilibrium position. The law is written as follows: F = -kx; in which "F" is the restoring force, "k" is the spring constant, and "x" is the spring's displacement.
