Answer:
Transverse wave- Back and forth at right angles to the direction of the wave arrow.
longitudinal wave- bask and forth in the direction of the motion of the motion of the wave.
electromagnetic wave- two alternating waves moving at right angles to each other.
Explanation:
In a longitudinal wave, the particles vibrate at right angles in reference to the wave motion.
In a transverse wave, the particles vibrate parallel to the wave motion
Electromagnetic waves occur as a result of the interaction between two waves and are normally transverse in nature.
We actually cant, really. Black Holes are really very powerful and don't just happen in some random place in the cosmos. We have got shots of Black holes that you cannot even see, but all the other big black holes that look like something straight of a sci-fi movie that look real, are really just photo- shopped. good question. Hope This Helped.
Answer:4.34 miles
Explanation:
first Elevation =
After 1 minute Elevation changes to 
Ditsance travelled in 1 minute =
=10 mile
Now
tan59=
H=xtan59
tan19=
H=
Equating H
we get
1.319x=10tan19
x=2.61 miles
H=
=4.34 miles
Answer:
<em>a. The molecules of solid are closely packed together</em>
<em>b. particles are so close, hence a high density</em>
<em>c.rate of diffusion is slow due to strong force of attraction between molecules of solid.</em>
Explanation:
(a)The molecules of solids are very much packed together hence very hard to compress and the force of attraction between molecules is strong hence very hard to expand . For this reason solids occupy a definite volume.
b. Because the molecules of solid is more closer than those of liquid and gas. Solids have a much higher density, hence a higher relative density. Density = mass/volume. for solids a huge amount of mass occupies a low volume space. A low volume and huge mass will result in high density
c. The diffusion of solids is very slow due to the strong force of attraction between the molecules of solids. However this diffusion can be made faster by the application of heat. This will increase the kinetic energy of the solid molecules.
