Answer:
A) 1.122 m
B) 5.4 hertz
C) 6.06 m/s ( towards negative x axis )
D) 0.22
E) max speed = amplitude * 34
= 0.22 * 34 = 7.48
minimum speed ( speed at rest ) = 0
Explanation:
The travelling wave = D = 0.22sin ( 5.6x + 34t)
this wave is represented in the form : D = Asin ( kx + wt)
A) wavelength
k = 2
/ v
v = wavelength
k = 5.6
therefore wavelength ( v ) from the equation = 2
/ 5.6 = 1.122 m
B ) frequency
w = 2
f
w = 34
f = frequency
therefore f = w / 2
= 34 / 2
= 5.4 hertz
C ) velocity
speed = f v
v = 5.4 * 1.122 = 6.06 m/s ( towards negative x axis )
D) amplitude
A = 0.22
E ) maximum and minimum speeds of particles on the chord
max speed = amplitude * 34
= 0.22 * 34 = 7.48
minimum speed ( speed at rest ) = 0
Answer:
White Lake was contaminated with the Chemical Complany dispersing their waste in the lake. Eventually, they were forced to stop dumping it into the lake
The equation for heat would be q = m*Delta T* S
Where q = the heat absorbed in joules
m = mass
Delta T = change in temperature
s = specific heat capacity of the material
for iron s = 0.450
Delta T = 23 - 13 = 10 degrees Celsius
m is given as 27 grams.
q = 27 * 10 * 0.450 = 121.5 joules
You may need to round the answer depending on what the teacher is looking for.
Answer:
Explanation:
let \theta be the inclination at which curve is tilted
v is the speed of car and R is the radius of curve
m is the mass of car
Suppose R is the reaction offered by road to car
Resolving R in x and y direction we get
will balance weight and
will provide the necessary centripetal Force
thus
------------1
----------------2
Divide 1 & 2 we get
Answer:
13.4 m/s
Explanation:
Write down what you have, so:
V0=8 m/s
a=2.7 m/s^2
t=2 seconds
We are trying to find final velocity, so we will use vf = v0 + at
From there, we plug in the given values.
vf = 8 m/s + (2.7 m/s^2 x 2 seconds)
vf = 13.4 m/s
