Answer:
The correct option is D) Fission
Explanation:
There are several methods through which Radioactive isotopes are created.
- Using a nuclear reactor that has a field of neutrons, insert a stable sample such as Lutetium-176. When it gets bombarded with neutrons, it acquires some, and fission is said to have occurred. Note that when Lutetium-176 acquires a neutron, it becomes radioactive Lu-177.
- Fission is also used to create Fluorine-18. To obtain the same, you need to bombard pure or enriched [
] water with ~18 MeV protons which are high energy in nature. The bombarding is achieved using a cyclotron or an accelerator.

Answer:
Attracting means pulling toward you and repelling means pushing away
Explanation:
Answer:
avriage force F = 2722.5 N
Explanation:
For this problem we can use Newton's second law, to calculate the average force and acceleration we can find it by kinematics.
vf² = v₀² - 2 ax
The final carriage speed is zero (vf = 0)
0 = v₀² - 2ax
a = v₀² / 2x
a = 1.1²/(2 0.200)
a = 3.025 m / s²
a = 3.0 m/s²
We calculate the average force
F = ma
F = 900 3,025
F = 2722.5 N
Answer:
W has the lowest density and Y has the greatest density
Explanation:
Density of W = mass/volume = 11/24 = 0.45
Density of X = mass/volume = 11/12 = 0.91
Density of Y = m/v = 5.5/4 = 1.375
Density of Z = m/v = 5.5/11 = 0.5
From these we can find the answer......
Hope this answer is useful......
