To understand the standard formula for a sinusoidal traveling wave. One formula for a wave with a y displacement (e. g., of a string) traveling in the x-direction is y(x, t)=Asin(kx−ωt). All the questions in this problem refer to this formula and to the wave it describes.
a. Which are the independent variables?
b. Which are parameters that determine the characteristics of the wave?
c. What is the phase phi(x, t) of the wave?
d. What is the wavelength lambda of the wave?
e. What is the period Tof this wave?
f. What is the speed of propagation v of this wave?

Which type of microscope would allow the viewer to see ribosomes inside a cell?

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
