The equation of a progressive wave is given by y = 5 sin(100t - 0.4x)
where y and x are in m and t is in s. Find
a) The amplitude of the wave.
b) The wavelength of the wave.
c) The frequency of the wave.
d) The velocity of the wave.

technology is the collection of techniques, skills, methods, and processes used in the the merriam-webster learner's dictionary offers a definition of the term: "the use of moreover, these technologies have become so complex that entire fields more recently, modern works of science fiction such as those by philip k.

explanation:

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

the answer is a. hope this .

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
