Answer:
The forces are balanced on both animals because they are not moving
More importantly than not moving is not <u>accelerating.</u>
Explanation:
Answer:
The acceleration of is
Explanation:
From the question we are told that
The mass of first block is
The angle of inclination of first block is
The coefficient of kinetic friction of the first block is
The mass of the second block is
The angle of inclination of the second block is
The coefficient of kinetic friction of the second block is
The acceleration of are same
The force acting on the mass is mathematically represented as
=>
Where T is the tension on the rope
The force acting on the mass is mathematically represented as
At equilibrium
So
making a the subject of the formula
substituting values
=>
Answer:
The box of rocks will have depression which can be seen without touching the box.
Explanation:
The density of rocks is very large as compared with napkins. So, the weight of the rocks will be much more greater than that of napkins.
As both boxes have same volume the heavier box will show depression on the lower surface as compared to the lighter box. So, the box of rocks will have depression which can be seen without touching the box.
The work done is by the centripetal force on mass m during an angular displacement of 2π revolutions mv²2π /r J
Centripetal force - a force acts on an moving object in circular path.
the centripetal force is given by
F= mv²/r (equation1)
Work done is given by
W = Fd (equation 2)
d = 2π
work is done by the centripetal force on mass m during an angular displacement of 2π revolutions is given by:
to calculate work done using equation 1 in 2 we get
W = mv² d/r
W = mv² × 2π /r J
The work done is by the centripetal force on mass m during an angular displacement of 2π revolutions mv²2π /r J
