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.

Answer:
I feel like static electricity is happening when we touch objects in our home
Answer:
330Ns
Explanation:
Given parameters:
Mass of the box = 5kg
Initial velocity = 0m/s
Force applied = 15N
Time = 22s
Unknown:
Impulse = ?
Final momentum = ?
Solution:
The impulse of the box can be determined using the expression below:
Impulse = Force x time
Impulse = 15 x 22 = 330Ns
The final momentum is the same as this impulse
The impulse and the final momentum is 330Ns
