Can be absorbed and transformed into heat. i know this because i used to work as a constructor for lights and i had to go over a training on this subject.
So, the temperature of a wave that has a wavelength of 5 m is
<h3>Introduction</h3>
Hi ! Here, I will help you to explain about The relationship between temperature and electromagnetic wavelength uses the principle of Wien's Constant. According to Wien, <u>if we multiply temperature with the electromagnetic wavelengths will always got the same number (constant)</u>. Therefore, The relationship is expressed in this equation :
With the following condition :
- C = Wien's constant ≈
- = wave at its longest point (m)
- T = absolute temperature (K)
<h3>Problem Solving</h3>
We know that :
- C = Wien's constant ≈
- = wave at its longest point = 5 m
What was asked :
- T = absolute temperature = ... K
Step by step :
<h3>Conclusion :</h3>
So, the temperature of a wave that has a wavelength of 5 m is
To answer this you must know that the acceleration caused by gravity upon the ball, or any object, is -9.8 m/s^2
there's two ways to solve this
first, use the position equation
x=(1/2)at^2+Vot+Xo
Xo, the initial position, is 3.5 m
x(t), the final position, is 0 m (the ground)
Vo, the initial velocity, is 0 m/s, since you just drop the ball
and a is -9.8
so
0=(1/2)(-9.8)t^2+3.5
-3.5=-4.9t^2
t^2=0.71
t=0.845
so it takes the ball 0.845 s to hit the ground
now, using the velocity equation, v=at+Vo,
v=(-9.8)(0.845)+0=-8.28 m/s
therefore, the speed of the ball is 8.28 m/s when it hits the ground
Answer:
36 m³
Explanation:
From gas laws, at a constant temperature, the product of volume and pressure are directly proportional hence expressed as p1v1=p2v2 where p is pressure while v represent volume. Subscripts 1 and 2 represent the initial and respectively. Making v2 the subject then
Substituting 120 kpa for P1, 12m³ for V1 and 40 kpa for p2 then
Therefore, the volume will be 36 m³
Acceleration no longer exist as the car stops.
