I'm quite certain the answer is "stress".
<span>Temperature causes water molecules to move more quickly, because each individual molecule has more energy as it gets hotter (according to Kinetic molecular theory). If you get water hot enough, the molecules move so much that the hydrogen bonds that hold them together start to break and the water becomes a gas ... water vapor. This your answer unless there are choices.</span>
Explanation:
The energy of a wave is given by :
Where
h is Planck's constant
c is the speed of light
is wavelength
Energy is inversely proportional to wavelength. Also, the relation between frequency and wavelength is inverse.
If the frequency is high, the wavelength will be shorter.
Hence, the correct options are :
Higher frequencies have shorter wavelengths.
Shorter wavelengths have lower energy.
Lower frequencies have lower energy.
Answer:
Explanation:
12 degree = (π / 180) x 12 radian
= .2093 radian
position of third bright fringe = 3λ D/ d where λ is wave length of light , D is screen distance and d is slit separation
given
3λ D/ d = 30 x 10⁻²
angular separation
3λ / d = .2093
from the two equation
.2093 D= 30 x 10⁻²
D = 30 x 10⁻² / .2093
= 1.43 m
