Answer:
Explanation:
a ) A force of 6 N , causes elongation of .03 m
Spring constant
k = 6 / .03
= 200 N / m
b )
Amplitude A = .04 m .
Maximum velocity of a particle in SHM
= ωA where ω is angular velocity and A is amplitude
= x A
= x A
= 20x .04 = 0.8
Maximum velocity of a particle
= 0.8 m ² s
Minimum velocity will be zero at extreme point ( at turning point )
c )
Minimum acceleration is zero at middle point ( equilibrium position )
maximum acceleration
= ω²A
= k / m x A
= 400 x .04
= 16 m / s
d )
At halfway point velocity will be √ 3 / 2 times the maximum velocity
velocity at mid point
= √ 3 / 2 x max velocity
.866 x
= .866 x 0.8
= .693 m /s
Answer:
700 N

Answer:
The given statement concerning distance and displacement is true.
Explanation:
If any point travels along any path between two points A and B the distance it travels is the length of the actual path it travels.
Mathematically the distance between two points is the algebraic sum of the infinitesimal distances that the particle travels.
Mathematically
Displacement by definition is the shortest distance between the initial and final positions of the particle and is given by the straight line joining the two points.
Since a line is the shortest path that exists between 2 points thus it will be always smaller than any other path connecting the 2 points hence will be smaller than the distance.
While as if the object travels along a straight line without changing it's direction the distance in that case equals the displacement.
To solve this problem it will be necessary to apply the concepts related to the electric potential in terms of the variation of the current and inductance. From this definition, we will start to find the load, which is dependent on the current as a function of time.
Here,
L = Inductance
Rate of change of current
If we take the equation and put the variation of the current as a function of time, in terms of the voltage in terms of the inductance we would have
The current as a function of time will be then,
The charge is the integral of the current in each variation of the time, then
Equation the terms we will have,
The electric field strength of a point charge is inversely proportional to the square of the distance from the charge ... a lot like gravity.
If the magnitude of the field is (2E) at the distance 'd', then at the distance '2d', it'll be (2E)/(2²). That's (2E)/4 = 0.5E .
