Answer:
a) , b) , ,
Explanation:
a) The system mass-spring is well described by the following equation of equilibrium:
After some handling in physical and mathematical definition, the following non-homogeneous second-order linear differential equation:
The solution of this equation is:
The velocity function is:
Initial conditions are:
Equations at are:
The spring constant is:
After some algebraic handling, amplitude and phase angle are found:
The position can be described by this function:
b) The period of the motion is:
The amplitude is:
The phase of the motion is:
Answer:
s(4)=450
Explanation:
Given Data
a(t)=30t+8
at t=0 s(0)=14
at t=0 v(0)=13
s(4)=?
Solution
we know v is derivative of a
and s is derivative of v
a(t)=30t+8
derivative it we get
so
derivative it we get
so
it is size of of particles because it does not matter about the size in a closed container
Answer:
875 cmil
Explanation:
Cross section area of wire=
Resistance of wire,
We have to find the cross sectional area of second wire
We know that
According to question
....(1)
...(2)
Equation (1) divided by equation (2) then, we get
Hence, the cross- sectional area of second wire=875 cmil
