Answer:
The distance is 1.4 km.
Explanation:
Given that,
Initial velocity u= 1.7 m/s
Accelerate a= 3.0 m/s²
Time = 30 s
We need to calculate the distance
Using equation of motion
Where, u = initial velocity
a = acceleration
t = time
Put the value in the equation
Hence, The distance is 1.4 km.

50 μm = 5 × 10⁻⁵ m in diameter
<h3>Steps</h3>
1μm = 1 x m
<h3>Given</h3>
1μm = 1 x m
50μm = 50 x m
50μm = 50 x 10 x
50μm = 5 x m
<h3>Conclusion</h3>
A human hair is approximately 50 μm = 5 × 10⁻⁵ m in diameter
<h3>How big is a human hair on average?</h3>
between 17 and 181 micrometers
The typical diameter of human hair can range from 17 micrometers to 181 micrometers, according to research. Using 50 micrometers as an average figure for its diameter, this translates to 50,000 nanometers.
<h3>What is a human hair's diameter in inches?</h3>
The finest hair is flaxen, with a diameter ranging from 1/1500 to 1/500 of an inch. the coarsest hair is black, measuring between 1/450 and 1/140 of an inch.

The force of gravity is the
force with which massively large objects such as the earth attracts another
object towards itself. All objects of the earth exert a gravity that is
directed towards the center of the earth. Therefore, the force of gravity of
the earth is equal to the mass of the object times acceleration due to gravity and also equal to the weight of the object.
