The high voltage generators which are used in X-Ray imaging system are magnetic devices. There are various magnetic X-rays imaging techniques.
X-rays are a form of electromagnetic radiations. X-ray imaging creates picture of the inside of your body. Polarized x-rays have emerged as unique probed due to their specific interaction with magnetic materials.Magnetic resonance imaging deals with
static and varying magnetic fields.
Answer:
The magnetic field is lowest for largest distance and highest when distance is least.
Explanation:
The magnitude of magnetic field strength at a distance 'r' from a long straight wire carrying current 'I' is given as:
Now, as per question, the distance 'r' is varied while keeping the current constant in the wire.
As seen from the above formula, the magnitude of magnetic field strength for a constant current varies inversely with the distance 'r'. This means that, as the value of 'r' increases, the magnitude of magnetic field strength decreases and vice-versa.
Therefore, the magnitude of magnetic field strength is maximum when the distance 'r' is least and the magnetic field is minimum for the largest distance.
Example:
If 
are the magnitudes of magnetic field strengths for distances 
respectively such that 
. Now, as per the explanation above, the order of magnitudes of magnetic field strength is:
Answer:
KE_2 = 3.48J
Explanation:
Conservation of Energy
E_1 = E_2
PE_1+KE_1 = PE_2+KE_2
m*g*h+(1/2)m*v² = m*g*h+(1/2)m*v²
(0.0780kg)*(9.81m/s²)*(5.36m)+(.5)*(0.0780kg)*(4.84m/s)² = (0.0780kg)*(9.81m/s²)*(2m)+KE_2
4.10J+0.914J = 1.53J + KE_2
5.01J = 1.53J + KE_2
KE_2 = 3.48J
The value of the c will be (0 i+0 j+0 k). c is a vector that is along the positive x-axis and has the condition a(b+c)=0.
<h3>What is a vector?</h3>
A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.
Given ;
a=3i-2j+k
b=-i-4j+3k
Given property:
a(b+c)=0
-i-4j+3k ((-i-4j+3k)+c)=0
(3+8+3)(-i-4j+3k)c=0
14(-i-4j+3k)c=0
c=0 i+0 j+0 k
Hence, the value of the c will be (0 i+0 j+0 k).
