Explanation:
The kinetic energy of an object is given in terms of its mass and object as :
An object with more mass has more kinetic energy. An object with less mass, if both objects are moving at the same speed, in opposite directions, will have less kinetic energy. The square of v will give positive number.
Answer:
Explanation:
From the question we are told that
Weight of fireman
Pole distance
Final speed is
Generally the equation for velocity is mathematically represented as
Therefore Acceleration a
Generally the equation for Frictional force is mathematically given as
Therefore
Answer:
The uncertainty in the location that must be tolerated is
Explanation:
From the uncertainty Principle,
Δ Δ
The momentum P = (mass of electron)(speed of electron)
=
=
If the uncertainty is reduced to a 0.0010%, then momentum
=
Thus the uncertainty in the position would be:
Δ
Δ
