Answer:
the one in which the fluid has the lowest density
The true statement is that the speed of the meteor is 7.8 Km/s.
<h3>What id the velocity?</h3>
The term velocity refers to the ratio of the change in the displacement to time. This definition applies strictly to rectilinear motion. In a case of a circular motion like the Ferris wheel in which the direction of the speed continues to change, we say that the velocity is changing because the direction is changing.
Now, the speed of the meteor was given to be 468 km/min. In order to obtain the speed in kilometer per second we have to divide the given value by 60. Thus the true statement is that the speed of the meteor is 7.8 Km/s.

Explanation:
Projectile motion is a form of motion where an object moves in parabolic path (trajectory). Projectile motion only occurs when there is one force applied at the beginning on the trajectory, after which the only interference is from gravity.
The range of an object experiencing projectile motion is given by:
R = u²sin(2θ) / g
where u is the initial velocity, θ is the angle with horizontal and g is the acceleration due to gravity
Given that R = 6.8 m, g = 10 m/s², u = 12 m/s.
R = u²sin(2θ) / g
substituting:
6.8 = 13²sin(2θ) / 10
13²sin(2θ) = 68
sin(2θ) = 0.4024
2θ = sin⁻¹(0.4024)
2θ = 23.73
θ = 11.86°
