The correct answer to this question is:
"D. Venus"
We know that by Hooke's Law,
F = kx; where F is the net force on the spring, k is the spring constant and x is the extension.
We are told that all the springs have the same spring constant as the first, so we first calculate its spring constant.
F = ma = 4.1 × 9.81
= 40.2 Newtons
k = 40.2 ÷ 0.13
k = 309 Newtons / m
Now, for the spring under consideration, the mass is
m2 = 12.3 kg
The net force will be the difference of the downward force of the mass's weight and the upward force of the elevator. Thus,
F = 12.3 × 9.81 - 12.3 × 4.2
F = 69 Newtons
x = 69 ÷ 309
x = 0.22 m = 22 cm
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:

Explanation:
To solve this equation we will have to consider that the bubble is filled with an Ideal Gas and as such we can use the Ideal Gas Law

Where
= Pressure
= Volume
= Moles
= Ideal Gas Constant
= Temperature
Now since we know that the value for the temperature and moles is constant we can simply use Boyles Law for the two states

Let us look at the two states
State 1 (at top)
Pressure = 
Volume = 
State 2 (at bottom)
Pressure = 
Where
= Density of liquid (1000 kg/m³)
= Acceleration due to gravity (9.8 m/s²)
= Height of liquid (0.200 m)
Pressure = 
Volume = 
Inputting these values into the Boyles Law

Disagree.
Fluoresce objects will only glow when put under actual Ultraviolet light. This is due to the molecules becoming excited by the ultraviolet radiation.
Microwaves give micro-waves that are present in another spectrum of wave length and will not be able to fluoresce the molecules. If it’s not “ultra violet “.... it’s not going to glow.
