Mechanics is dealing with forces that are effecting some body, electrostatics is about electrical fields of not moving bodies, and quantum mechanics is dealing with quantum states of atoms.
Thermodynamics as the word say, is dealing with thermal energy that is moving (transferring from one body to another or even better from one medium to another).
Answer is C <span />
Answer:
true
Explanation:
takes time for most plates to move but throughout time they keep moving just at a slow pace
Answer:
The work done is L= 49.83 Joules
Explanation:
m= 2.44kg
d= 1.55m
α= 69.6°
g= 9.8 m/s²
μ= 0.691
F= ?
Fy= F*sin(α)
Fx= F*cos(α)
Fr= μ * Fx
Fr= μ * F*cos(α)
W= m*g
W= 23.91 N
Fy - W - Fr = 0
F*sin(α) - W - μ * F*cos(α) = 0
F* ( sin(α) - μ *cos(α) ) = W
F= W / ( sin(α) - μ *cos(α) )
F= 34.3 N
L= Fy * d
L= 49.83 J
Given :
An object with weight 20 N was lifted to 0.5 meters.
To Find :
How high must you lift a 25 Newton book for it to have the same increase in potential energy as the given book.
Solution :
Since both have same potential energy :
Putting all given values in above equation :
Therefore, book with same potential energy is at a height of 0.4 m.
