A periodic transverse waves is created by shaking one of a string side to side periodically.ten oscillations are completed in 2.00 seconds.It is known that the wave speed is 2.00 m/s. Calculate frequency of the wave, period of the wave and the wave length
An object placed 5cm in height is placed 10cm from a curved mirror and produces a virtual image of 6.5cm height. Where is the image located and what type of mirror is this
A ball is thrown at an angle of 50 degrees above the horizontal. After 5 s, the ball is at a distance 38 m along the horizontal from the point where it was released. How high is the ball above the point where it was released during this time?
A ball is thrown at an angle of 50 degrees above the horizontal. After 5 s, the ball is at a distance 38 m along the horizontal from the point where it was released. What is the initial velocity of the ball?
A 2 kg cube attached to a spring oscillates in simple harmonic motion along an x-axis on a smooth surface. Its position is given by X = 0.050 cos (2t +pi), where X is in meters and T is in seconds. i. Define simple harmonic motion and time period. (1 mark) ii. What is the angular frequency, frequency, amplitude and phase angle or phase constant of the motion? (4 marks) iii. What is the spring constant K, for the spring? (2 marks) iv. What is the velocity and acceleration of the cube at T = 3 S? (5 marks) v. What is the kinetic energy in Joules of the cube when it is at X = 3 M?
An object 5cm high is placed 20cm in front of a concave mirror and produces an image 60cm from the mirror. Find the height of this image
Two blocks A and B are connected by a light flexible chord which passes over a frictionless pulley. The mass of block is 3kg. Block A rests on an inclined plane whose angle of inclination is 35 degrees. What must be the mass of block B so that the system will be in equilibrium? There is no friction anywhere in the system
