Here's the solution :
Let's find the final velocity :
Initial velocity (u) = 0 (cuz it started from rest)
Final velocity (v) = 8 m/s
Time taken (t) = 10 sec
now, we know that :
Acceleration = 0.8 m/s²
<span>It is the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
Every planet has their own corresponding escape velocities. Example - Earth has escape velocity of 11.2 Km/s. It means, if you want to leave the Earth's gravitational field then it's the lowest speed which you need to acquire otherwise you wouldn't do that!
Hope this helps!</span>
Answer:



Explanation:
= Uncertainty in position = 1.9 m
= Uncertainty in momentum
h = Planck's constant = 
m = Mass of object
From Heisenberg's uncertainty principle we know

The minimum uncertainty in the momentum of the object is 
Golf ball minimum uncertainty in the momentum of the object

Uncertainty in velocity is given by

The minimum uncertainty in the object's velocity is 
Electron


The minimum uncertainty in the object's velocity is
.
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. ... They are hence known as 'electromagnetic' waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other.
