-40 c = -40 f but k would be 233.15
Answer: 8 years
Explanation:
According to Kepler’s Third Law of Planetary motion <em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”:</em>
<em />
(1)
In other words: this law states a relation between the orbital period of a body (moon, planet, satellite, comet, asteroid) orbiting a greater body in space (the Sun, for example) with the size of its orbit.
However, if is measured in years (Earth years), and is measured in astronomical units (equivalent to the distance between the Sun and the Earth: ), equation (1) becomes:
(2)
This means that now both sides of the equation are equal.
Knowing and isolating from (2):
(3)
(4)
Finally:
This is the period of the asteroid
Answer:
False
Explanation:
Diffraction is slight bending of the light as it passes around edge of object.
It is caused as one wave of the light being shifted by the diffracting object. The shift will then cause wave to have the interference with itself. The interference can be constructive or destructive.
The patterns of the interference rely on size of diffracting object and size of wave.
Hence, the given statement is incorrect.
Answer:
Up And Down
Explanation:
In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.
Hope this helps..Pls mark as Brainliest!!
Answer:
C. perpendicular to one another and perpendicular to the direction of wave propagation.
Explanation:
An Electromagnetic wave (EM wave) is a wave having both electric and magnetic components in it. These wave radiates electromagnetic energy while propagating through the space. The electric and magnetic field component of the wave have an angle of 90° to each other aming them perpendicular while they both are perpendicular to the direction of wave propagation as well.
Some examples of EM waves are: UV rays, IR radiation, Radio waves etc. These waves propagate at the speed of light in vacuum.
