Answer: (C) Radioactive dating</h2>
Explanation:
Let's begin by explaining that radioactive decay is a spontaneous process in which the nucleus of an atom disintegrates, giving way to the emission of radiation and the appearance of a new nucleus, releasing energy in the process.
<u>This process is widely used in</u><u> radioactive dating</u> (also called isotopic dating or radioisotope dating) in which radioactive impurities were selectively incorporated when the fossil materials were formed.
In this sense, when dating the age of the Earth and its components, it is useful to compare them with a naturally occurring radioisotope having a known half-life (generally uranium-238 is used and sometimes carbon-14).
The total energy stored in the capacitors is determined as 2.41 x 10⁻⁴ J.
<h3>What is the potential difference of the circuit?</h3>
The potential difference of the circuit is calculated as follows;
U = ¹/₂CV²
where;
- C is capacitance of the capacitor
- V is the potential difference
For a parallel circuit the voltage in the circuit is always the same.
The energy stored in 2.5 μf capacitor is known, hence the potential difference of the circuit is calculated as follows;
U = ¹/₂CV²
2U = CV²
V = √2U/C
V = √(2 x 1.8 x 10⁻⁴ / 2.5 x 10⁻⁶)
V = 12 V
The equivalent capacitance of C1 and C2 is calculated as follows;
1/C = 1/C₁ + 1/C₂
1/C = (1)/(0.9 x 10⁻⁶) + (1)/(16 x 10⁻⁶)
1/C = 1,173,611.11
C = 1/1,173,611.11
C = 8.52 x 10⁻⁷ C
The total capacitance of the circuit is calculated as follows;
Ct = 8.52 x 10⁻⁷ C + 2.5 x 10⁻⁶ C
Ct = 3.35 x 10⁻⁶ C
The total energy of the circuit is calculated as follows;
U = ¹/₂CtV²
U = ¹/₂(3.35 x 10⁻⁶ )(12)²
U = 2.41 x 10⁻⁴ J

#SPJ1
Answer:
Water leaves the sprinkler at a speed of 2.322 m/sec
Explanation:
We have given internal diameter of the garden
Speed of water in the hose is
Number of holes n = 22
Diameter of each holes
According to continuity equation
So water leaves the sprinkler at a speed of 2.322 m/sec
a. subduction.
Explanation:
A subduction zone is a zone where the oceanic crust dives beneath the continental crust.
- Subduction zones are typical features of convergent margins where two plates pulls together.
- They are formed by continent-oceanic covergence and ocean - ocean covergence.
- In oceanic - continent convergence, the denser oceanic crust slides under the continental crust because it is denser than the mantle below.
- In oceanic - oceanic crust convergence, either of the plate slides under the other into the mantle.
- Trenches, volcanoes, earthquakes are typical geologic features associated with them.

The amplitude cannot be determined.
Explanation:
Given the parameters in the problem statement, it is impossible to determine the amplitude of the wave.
The velocity of the wave cannot be determined from the information of the velocity and period of the wave.
Velocity of the wave;
Velocity = Frequency x Wavelength
- The amplitude of a wave is the vertical displacement of a wave from rest.
- Amplitude of a wave is not related to velocity of a wave.
