Answer: The correct answer is option(B.).
Explanation:
The co-formation theory explain that both moon and the earth are formed at same time from the primitive solar nebula (cloud made up of dust and gases) at the same and same place.
Where as capture theory suggests that the moon is an asteroid which was formed or created somewhere else in a solar system. And when the moon approached the earth planet it got captured by the earth's gravitational field.
Impact theory explains the formation of moon by the catastrophic collision between the earth and any planet half the size of earth's size.
Synchronous theory sheds the light on the rotation time, revolution time and sides of moon located from the surface of the earth.
Hence, the correct answer is option(B).
Answer:
frequency
Explanation:
I think it's frequency because when frequency of a sound wave increases we feel increase in pitch
Answer:
2.4 m/s
Explanation:
Given:
Velocity of the object moving north = 2.1 m/s
Velocity of the river moving eastward = 1.2 m/s
The resultant velocity is the vector sum of the velocities of object and river.
Since the directions of velocity of object and river are perpendicular to each other, the magnitude of the resultant velocity is obtained using Pythagoras Theorem.
The velocities are the legs of the right angled triangle and the resultant velocity is the hypotenuse.
The magnitude of the resultant velocity (R) is given as:
Therefore, the resultant velocity has a magnitude of 2.4 m/s.
To solve this problem it is necessary to apply the concepts related to the Heisenberg's uncertainty principle. Under this principle we understand the relationship that the minimum range of error in position (x) times the minimum range of error in momentum (p) is, at a minimum, about equal to the Planck constant, mathematically that is,
Replacing with our values we have,
Therefore the least uncertainty in any simultaneous measurement of the momentum component px of this electron is
