The kinetic energy of photoelectrons increases with light frequency. Electric current remains constant as light frequency increases. Electric current increases with light amplitude. The kinetic energy of photoelectrons remains constant as light amplitude increases.
Q. What is total energy of SHM?
In the SHM of the mass and spring system, there are no dissipative forces, so the total energy is the sum of the potential energy and kinetic energy. As the object starts to move, the elastic potential energy is converted into kinetic energy, becoming entirely kinetic energy at the equilibrium position.
Q. What is the frequency of kinetic energy in SHM?
Kinetic energy however does not depend on direction of velocity as it depends on v2, hence in the same time period it is achieved 2 times, hence its frequency is twice that of velocity.
Q. What is potential energy frequency?
frequency of above equation i.e. frequency of P.E. is 2ω or 2n.
Q. What would be the angular frequency of the kinetic energy oscillations?
The angular frequency ω is given by ω = 2π/T. The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time.
Q. At what position is acceleration maximum?
Acceleration has a different story. At the middle (x = 0), acceleration is zero. At the extreme ends, when a spring is at its maximum stretch or compress, the spring force is at its maximum magnitude, and therefore the acceleration it gives to the attached mass is maximum.
Q. How do you find the mass and frequency of a spring constant?
Kinematics of Spring-Block Oscillators — Determining the frequency from the mass of the block and the spring constant using f = 1/2π √ (k/m)
Q. How do you find the resonant frequency of an object?
Use the formula v = λf to find the resonance frequency of a single continuous wave. The letter “v” stands for the wave velocity, whereas “λ” represents the distance of the wavelength. This formula states that the wave velocity equals the distance of the wavelength multiplied by the resonance frequency.
Q. Does spring constant have units?
The units for the spring constant, k, are Newtons per meter (N/m). Hooke’s law equation states that F = kx, where F is the force required to compress…
Q. What is the equation for spring force?
The force exerted by a spring on objects attached to its ends is proportional to the spring’s change in length away from its equilibrium length and is always directed towards its equilibrium position. F = -kx. The proportional constant k is called the spring constant. It is a measure of the spring’s stiffness.
Q. Does constant force mean no acceleration?
Acceleration and velocity Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.
