Explanation:
According to Newton's second law of motion, the rate of change of momentum is directly proportional to the applied unbalanced force. The mathematical expression is given by:
Where
F is the applied force
m is the mass of the object
v is the velocity with which it is moving
Momentum of a particle is given by the product of mass and velocity as :
Hence, this is the required solution.
A) travel outside the necleus
Answer:
v = 60 m/s
Explanation:
It is given that,
A wave is represented by the equation :
We need to find the velocity of the wave
The general equation of a wave is given by :
....(1)
Equation (1) can be written as :
...(2)
If we compare equation (1) and (2) we get :
The velocity of a wave is given by :
So, the velocity of the wave is 60 m/s.
Answer:
d = v² / (2μ g)
Explanation:
In the work relationship is equal to the variation of energy,
W = ΔEm
The work is defined by
W = F. d = F d cos θ
In this case the outside is the force of friction, which always opposes
to the movement, so the angle is 180 °
W = - fr d
The force of friction can be found with Newton's second law
fr = μ N
Y Axis
N- W = 0
N = mg
fr = μ m g
We substitute in the expression of work
W = - μ mg d
Now we use the relationship of work and energy
-μ mg d = 0 -½ m v²
d = v² / (2μ g)
C- Stratus clouds are the rainy clouds.
