Answer:
K
Explanation:
The Heisenberg uncertainty principle is
Δx Δp ≥ h' / 2
h’ =
The kinetic energy of a particle is
K = ½ m v²
p = mv
v = 
substitute
K = 
from the uncertainty principle,
Δp = 
we substitute
K = 
The correct answer is option D
The Ohm's Law states that current passing through a conductor is directly proportional to the voltage across the conductor.
Current =voltage/ resistance
The resistance causes hindrance in the path of the current and does not allows it to flow so, we must reduce the resistance to increase the flow of current in the conducting wire.
Answer:
Depends on how long the string is, how heavy the weight, and how high you let go of it.
But it will most likely hit you :)
Answer:
0.196 m
Explanation:
Given in the question that,
time taken by the dolphin to go back to water = 0.2 sec
To solve the question we will use Newton's Law of motion
<h3>S = ut + 0.5(a)t²</h3>
here S is distance covered
u is initial speed
a = acceleration due to gravity
t = time taken
Plug value in the equation above
S = 0(0.2) + 0.5(-9.8)(0.2)²
S = 0.5(-9.8)(0.2)²
S = -0.196 m
Negative sign represent direction
(Assuming that dolphin have a vertical straight jump not a projectile motion)
