Answer:
<em>2</em><em>, The spring would compress twice the length of </em><em>. </em>
Explanation:
The Spring force is an application of Hooke's law, and using the law of conservation of energy in a spring system, we can find the relationship between the compression length and velocity.
<h3>Step by Step Calculations</h3>
For a spring system, the conservation of energy can be applied using the formula below;
........................................1
Where k is the spring constant
is the distance
m is the mass and
v is the velocity
We have to make the distance the subject formula to know how it affects the velocity;
.....................................2
from the equation, it shows that the distance () is directly proportional to the velocity (v). This implies that when the distance increases the velocity also increases.
x ∝ v
Therefore when the initial speed is doubled to 2 v it will amount a double increase in the distance which is 2
Explanation:
...domains are aligned which creates a magnetic field.

Answer:
v = 8.89 cm/s
Explanation:
given,
frequency of ultrasonic wave = 2.23 x 10⁶ Hz
beat frequency = 258 Hz
speed of sound in the tissue = 1.54×10³ m/s
maximum velocity = ?
using Doppler equation
..........(1)
..........(2)
now, from equation (1) and (2)
f₂ = 2.23 x 10⁶ + 258 = 2230258 Hz
f₀ = 2.23 x 10⁶ Hz
c = 1540 m/s
1.00012(1540 - v ) = 1540+ v
1540.178 - 1.00012 v = 1540 + v
2.00012 v = 0.178
v = 0.08899 m/s
v = 8.89 cm/s
