The figure shown carriage has a mass of 365 kg when passing
through point A with a speed of 19.7 m / s , the height of 7.6 m
above ground level ( y = 0). The instant that passes through C
decreased its speed to 8.3 m / s . Assuming the route
frictionless.

The speed of a wave in a string is given by v = sqrt(FT/μ), where FT is the tension in the string and μ = mass/length of the string. A 2.00 m long string has a mass of (A+1.50) g. A (B+25.0) g mass is attached to the string and hung over a pulley (see illustration from one of the...

Please explain which one is correct and why
In 1923, de Broglie argued that since light can display wave and particle properties, then matter can also be a particle and a wave too. Using dimensional analysis, then according to de Broglie the wavelength of an electron of mass m_e moving at velocity nu is given by A) lambda = m_e...

The cladding in a typical multimode cylindrical fiber is only 35 um thick, and yet in analysis of wave propagation of fibers it is assumed to be infinitely thick. Assuming this is permissible only so long as the evanescent wave has attenuated 10 dB at the outer cladding boundary, how long can the wavelength of 89'incident light get before this...

2. The unational method is an incredibly simple but surprisingly powerful method for understanding the low- energy behavior of quantu systems. It is used constantly in marny-body physics and in quantum chemistry. The main idea is thst for any physical Hamiltonian, there is a lowest energy state, i.e. the ground state Ipo). All other states (ignoring degeneracy) have higher energy...

A point charge q = +39.0 µC moves from A to B separated by a distance d = 0.184 m in the presence of an external electric field E with arrow of magnitude 295 N/C directed toward the right as in the following figure. A positive point charge q is initially at point A, then moves a distance d to...
