Calculate the first cosmic velocity for the planet Jupiter. The radius of Jupiter is R = 7 × 10⁴ km, while the acceleration of free fall near the planet's surface is g = 26 m / s
A string on a cello has a tension of 34.5N. The linear density is 0.05g / m . What is the speed of sound along the string ?
What is the speed of an AM radio wave with a frequency of 10 ^ 6 * H * z and a wave length of 300m ?
Draw a diagram of the geometric features of waves (e.g. a sine wave) and indicate the location of the followingcrest, trough, wavelength, phase shift, amplitude and equilibrium point.
Two spheres with masses m 1 = 800 g and m2 = 400 g move along a line following each other with velocities v1 = 5 m / s and v2 = 4m / s. a) Calculate the pulse of the system. b) Will the spheres be hit? Why ? c) What will be the impulse of the system after the shock?
Describe transverse, longitudinal and complex waves and give an example for each type.
Compare and contrast particle behaviour between solid and fluid media.
The material point with mass m = 500 g performs rectilinear motion and is under the action of constant force F = 50 N. Calculate the change of momentum during delta t1; = 0.5 s and delta t2 = 2 s
What is a vibration and how does it make mechanical wave?
Calculate the force of gravitational pull between the electron and the proton on the hydrogen atom. It is known that the radius of the electron orbit is R = 0.5 × 10 ‐ ¹⁰m, the mass of the electron m1 = 9.1 × 10 ‐ ³¹ kg and the mass of the proton m2 = 1.67 × 10 ‐ ²⁷ kg. Compare the conclusion you will find with the value of the electric gravitational force, which is Fel = 9 × 10 ‐⁸ N. What conclusion can you formulate?
