Answer:
The minimum uncertainty in its speed is greater than
.
Explanation:
It is given that,
Speed of the particle, 
We need to find the minimum uncertainty in its speed. It can be calculated using uncertainty principle as :

Since, p = mv






So, the minimum uncertainty in its speed is greater than
. Hence, this is the required solution.
Answer:
6.56km
Explanation:
Given parameters:
Speed = 11.5km/hr
Time = 2060s
Unknown:
Distance covered = ?
Solution:
Speed is distance divided by the time taken.
Speed =
Distance = Speed x time
Let us convert the seconds to hours;
3600s = 1hr
2060s =
= 0.57hr
Now
Distance = 11.5km/hr x 0.57hr = 6.56km
Answer:To protect the human body from foreign bodies from the outside environment.
Explanation:
Answer:
6.16 m/s
0.0105 m
Explanation:
Let the ground 0 for potential reference be at where the spring is compress 0.24 m. The the man would jump from a height h = 2.5 + 0.24 = 2.74 m from it. We can apply the law of energy conservation knowing that as the man jumps, his potential energy converts to kinetic energy, then finally to elastic energy:


where m = 80 kg is the man mass, g = 9.81 m/s2 is the gravitational acceleration, h = 2.74 m is the potential distance he travels, k N/m is the spring constant and x = 0.24 is the distance it compresses



Similarly at the position where it compresses by 0.12 m, it's 0.24 - 0.12 = 0.12 m far from ground 0.







When he steps gently, then his gravity force would equal to his spring force


What Newton discovered is that gravity extends throughout the universe.
<h3>What is gravity?</h3>
The term gravity refers to the force that acts on a body in the universe. It is gravity that makes an object to fall when it is thrown up. The force of gravity acts on every object in the universe and it extends through the universe.
Humans have always known about gravity when they fall from a height and when they threw things up. However, human did not know that gravity extends throughout the universe.
Thus, what Newton discovered is that gravity extends throughout the universe.
