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 force exerted by the wood on the bullet is 399.01 N
Explanation:
Given;
mass of bullet, m = 0.0021 kg
initial velocity of the bullet, u = 497 m/s
final velocity of the bullet, v = 0
distance traveled by the bullet, S = 0.65 m
Determine the acceleration of the bullet which is the deceleration.
Apply kinematic equation;
V² = U² + 2aS
0 = 497² - (2 x 0.65)a
0 = 247009 - 1.3a
1.3a = 247009
a = 247009 / 1.3
a = 190006.92 m/s²
Finally, apply Newton's second law of motion to determine the force exerted by the wood on the bullet;
F = ma
F = 0.0021 x 190006.92
F = 399.01 N
Therefore, the force exerted by the wood on the bullet is 399.01 N
The human brain did not “give itself” the name “brain”. A network of brains (i.e. society) agreed over time on calling the gray think-tank in our skulls a “brain”. Different networks in other environments agreed on other terms to label the same object. Over time these networks evolved, constantly creating slightly-tweaked yet new names, based contextually on what they were already calling other objects (these constitute what we know as linguistic relationships).
Substances that are considered acidic are also called alkaline: TRUE
Hope this helps :)
