the wave function that describes a certain transverse wave at initial time t=0 is y(x,y)= (7.20mm)sin2π[x•0.3m-t•0.0400 s]
Vectors and are shown in the figure. Vector is given by = - . The magnitude of vector is 16.0 units, and the magnitude of vector is 7.00 units. What is the angle of vector , measured counterclockwise from the +x-axis?
given the equal of the wave y(x, t)= 1.0mcos(2πm^-1 ×-π/3s t)
A velocity of magnitude 40m per sec is directed at an angle of 40degree east of north.draw a vector to represent this velocity
“Write the name of at least five modern devices, whose working principle is based on Maxwell Equations
Calculate de broglie wavelength and velocity of an electron carrying kinetic energy 2keV
A hose directs a horizontal jet of water, moving with a velocity of 20m/s on to a vertical wall. The cross sectional area of the jet is 5 * 10^-4. If the density of water is 1000kg/m^3, calculate the force on a wall assuming the water is brought to rest there.
a christmas ball in a shape of a hollow sphere is hung from the tree by a piece of thread attached to the surface of the ball the mass and radius of the ball are zero point 105 kg and 0.12 m respectively what will be its period of oscillation when slightly displaced from its equilibrium position?
Susan carried out an experiment in which she took measurements of the height of her students and the number of students in her Basic Science class. She then categorized the number of students against their heights and write down the information in a laboratory notebook.
If Susan wants to present this information in the form of graph, which graph will be appropriate for presenting this information?
(a) Identify conduction electrons and explain their role in making a conducting object negatively or positively charged.
(b) For either of the particles in a pair of Charged Particles apply Coulomb’s law to relate the magnitude of the particles, and separation between the particles
(c)(a) Distinguish between being electrically neutral, negatively charged, and positively charged and identify excess charge
