To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition. ... With absolute age dating, you get a real age in actual
The magnetic field within the solenoid is 0.013T
<h3>What is Solenoid ?</h3>
An electromagnet known as a solenoid creates a regulated magnetic field using a helical coil of wire whose length is significantly higher than its diameter. When an electric current is sent through the coil, it may create a consistent magnetic field inside a defined region of space.
A solenoid operates by creating an electromagnetic field surrounding an armature, which is a moving core. The electromagnetic field causes the armature to move, and when it does, it opens and closes valves or switches, converting electrical energy into mechanical motion and force.
The magnetic field within the solenoid can be calculated by the expression given below.
Write the expression for magnetic field within the solenoid.
B = u₀nI
B = 4π * 10⁻⁷ * 2000 * 5.2
= 0.013 T

Answer:
C
Explanation:
This is right because that's how u describe it
XA = PA/PA^0
XA = 22.98/23.76 = 0.9671
0.9671 : 0.0328
bi = ni/msolvent
0.9672 * 18.015/1 mol = 17.42 g H2O
bi = 0.0328 mol urea/17.42 g H2O * 1000
bi = 1.88 m
hope this helps
