d = distance the bowling ball has fallen = ?
g = acceleration due to gravity acting on the ball by earth = 9.8 m/s²
t = time of fall for the ball = 3.0 s
distance the ball has fallen is given as
d = (0.5) g t²
inserting the above values in the equation above
d = (0.5) (9.8 m/s²) (3.0 s)²
d = (0.5) (9.8 m/s²) (9.0 s²)
d = (4.9 m/s²) (9.0 s²)
d = 44.1 m
hence the distance fallen by the ball comes out to be 44.1 m
Answer:
Moment of the 4N force = 16Nm
Moment of the 6N force = 12Nm
Explanation:
Find the diagram attached.
Moment of a force is the product of the force and the perpendicular distance from the point of application
For the 4N force
Distance of the force from O is 4m
Moment of the 4N force = 4N * 4m
Moment of the 4N force = 16Nm
For the 6N force
Distance of the force from O is 2m
Moment of the 6N force = 6N * 2m
Moment of the 6N force = 12Nm

Answer: A scalar quantity has magnitude but no particular direction and a vector quantity has magnitude and acts in a particular direction.
Explanation:
I would say B because we used telescopes for space, right? And we can see the light.
