3. Twelve waves pass a dock in 3.60 If the waves are traveling at 19.5 m/s , what is the wavelength of the waves?
otez555 [7]

Answer:

65m

Explanation:

Twelve waves pass a dock in 3.60 If the waves are traveling at 19.5 m/s , what is the wavelength of the waves?

Velocity of a wave is expressed as;

V = frequency × wavelength

Given

Velocity = 19.5m/s

Frequency is the number of oscillations completed in 1sec, hence

Frequency= 3.6/12

Frequency = 0.3

Wavelength = vel/freq

Wavelength = 19.5/0.3

Wavelength = 65m

A conveyor belt is used to move sand from one place to another in a factory. The conveyor is tilted at an angle of 18° above the
brilliants [131]

Answer:

x = 2.044 m

Explanation:

given data

initial vertical component of velocity = Vy = 2sin18

initial horizontal component of velocity = Vx = 2cos18

distance from the ground yo = 5m

ground distance y = 0

from equation of motion

y = yo+ V_y t +\frac{1}{2}gt^2

0 = 5 + 2sin18+ \frac{1}{2}*9.8t^2

solving for t

t = 1.075 sec

for horizontal motion

x = V_x t

x = 2cos18*1.075

x = 2.044 m

at the extact same time, youj drop a piece of notebook paper and your science out the window. the science book hit first? why?
jeyben [28]
The piece of paper has less mass and will glide down the window, whereas the textbook will go straight to the ground. Since the textbook has more mass and less ways of it being able to 'glide' the textbook will hit the ground first.
