Answer:
The work done by gravity during the roll is 490.6 J
Explanation:
The work (W) is:
<em>Where</em>:
F: is the force
d: is the displacement = 20 m
The force is equal to the weight (W) in the x component:
<em>Where:</em>
m: is the mass of the bowling ball = 5 kg
g: is the gravity = 9.81 m/s²
θ: is the degree angle to the horizontal = 30°
Now, we can find the work:
Therefore, the work done by gravity during the roll is 490.6 J.
I hope it helps you!
Answer:
The value is
Explanation:
From the question we are told that
The initial speed is
Generally the total energy possessed by the space probe when on earth is mathematically represented as
Here is the kinetic energy of the space probe due to its initial speed which is mathematically represented as
=>
=>
And is the kinetic energy that the space probe requires to escape the Earth's gravitational pull , this is mathematically represented as
Here is the escape velocity from earth which has a value
=>
=>
Generally given that at a position that is very far from the earth that the is Zero, the kinetic energy at that position is mathematically represented as
Generally from the law energy conservation we have that
So
=>
=>
=>
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 .
