Answer:
Capture Theory
Explanation:
According to capture theory, moon is passing space rock-asteroid which was captured into the orbit around the Earth due to gravity. Other planets have moons which are captured asteroid like Mars has two moons-Phobos and Deimos. Jupiter has many moons which are captured asteroids. Capture theory explains the difference in the composition of Earth and the moon.
Answer:
Therefore the horizontal range = 294897.96 m.
Explanation:
Range of a projectile: The range is defined as the horizontal distance from the point of projection to the point where the projectile hit the projection plane again. The S.I unit of range is Meter (m).
It can be expressed mathematically as
R = u²sin2∅/g............................. Equation 1
Where R = Horizontal range, ∅ = angle of projection, u = initial velocity, g = acceleration due to gravity.
Given: u = 1700 m/s, ∅ = 55°,
Constant: g = 9.8 m/s²
Substituting these values into equation 1
R = (1700²sin55)/9.8
R = 2890000/9.8
R = 294897.96 m.
Therefore the horizontal range = 294897.96 m.
The Correct Answer Is 0.33.
