dens = mass/volume. after crushing, vol less so density more. the actual density of the metal is the same, density of can changes
Answer:
The maximum electric field
Explanation:
From the question we are told that
The diameter is
The magnetic field of the cylinder is
The frequency is
The radial distance is
This magnetic field can be represented mathematically as
The initial magnetic field is the average between the variation of the magnetic field which is represented as
Then is the amplitude of the resultant field is mathematically evaluated as
The electric field induced can be represented mathematically as
At maximum electric field
OPTION (C) IS CORRECT
ANSWER - UNIFORM MOTION
If there is no change in the velocity of the object then it is known to be in <u>UNIFORM MOTION</u>.

Answer:
Position of x at t = 1.44s is - 0.0817 m
Explanation:
For the harmonic motion of the spring, the displacement is given by
x = A cos wt
A is the amplitude of displacement = 0.14 m
t = time = 1.44 s
w = angular frequency and for a spring's motion, it is given by
w = √(k/m)
k = spring's stiffness = 6.5 N/m
m = 2.8 kg
w = √(6.5/2.8) = 1.524 rad/s
x = 0.14 cos (1.524 × 1.44) = 0.14 cos 2.194 = 0.14 × - 0.5836 = - 0.0817 m
