Answer:
Option C.
Explanation:
<u>Natural uranium is composed by 99.27% of U-238, 0.72% of U-235 and 0.005% of U-234</u>.
Of the isotopes of natural uranium, the U-235 is the most commonly utilized in nuclear power plants, but since it is only 0.72% of natural uranium it needs to be enriched before being used as fuel to sustain a nuclear fission reaction in nuclear power plants.
<u>The U-238 is the most common and the heaviest of the three naturally occurring isotopes of uranium</u>.
So, from the above the correct option is the C.
Have a nice day!
Answer:
To strike or crash into with resounding impact. To collide or strike with great force. Used to indicate the sound of a forceful blow or collision.
In the first figure, the surface absorbs all colors except for green light, which is reflected: so, the surface will appear as green to our eyes, because green is the only color which is reflected by that surface.
Similarly, in the second figure, the surface absorbs all colors except for blue, and so the surface will appear blue to our eyes.
In the third figure, the surface absorbs all colors, so it will appear black to our eyes (because no colors are reflected, and black=absence of colors).
In the fourth figure, all colors are reflected: this means the surface will appear white to our eyes (white= sum of all colors).
Answer:
B = 0.0307 T = 30.74 mT
Explanation:
Given
m = 0.150 kg
I = 15.0 A
d = 0.510 m
μk = 0.16
B = ?
Balancing the forces on the rod in the <em>j</em> direction
N - m*g = 0 ⇒ N = m*g
and in the <em>i</em> direction
I*d*B - μk*N = 0 ⇒ B = μk*N / (I*d)
⇒ B = μk*m*g / (I*d)
⇒ B = (0.16)*(0.150 kg)*(9.8 m/s²) / (15.0 A*0.510 m)
⇒ B = 0.0307 T = 30.74 mT
