Answer: The soil will be warmer than the water.
Explanation:
The heat (thermal energy) absorbed can be found using the following equation:
Where:
is the heat
is the mass of the element
is the specific heat capacity of the material.
is the variation in temperature
<u>In the case of soil we have:</u>
(1)
Where:
<u>In the case of water we have:</u>
(2)
Where:
Isolating from both equations:
(3)
(4)
(5)
(6)
Comparing (4) and (6) we can find the soil will be warmer than the water.
Answer:
1. Solid to liquid:ice cube melting into water.
2. Liquid to gas:water boiling
3. Solid to gas:dry Ice transfer into carbon dioxide directly.
Explanation:
The term phase transition (or phase change) is most commonly used to describe transitions between solid, liquid, and gaseous states of matter, as well as plasma in rare cases.
The frequency of the wave is determined as 7.96 Hz.
<h3>
Frequency of the wave</h3>
The frequency of the wave is calculated as follows;
y = A sin(ωt - kx)
where;
- A is amplitude of the wave
- ω is angular speed of the wave
ω = 2πf
f = ω/2π
f = (50)/(2π)
f = 7.96 Hz
Thus, the frequency of the wave is determined as 7.96 Hz.

Answer is 240 ohms
Use the equation V=IR, rearranging it to make R (resistance) the subject.
R = V/I
Substitute the values:
V = 120
I = 0.5
Resistance = 120 / 0.5
Resistance = 240 ohms
