Answer:
The answer is
<h2>0.14 g</h2>
Explanation:
To find the mass of a substance given the density and volume we use the formula
<h3>mass = Density × volume</h3>
From the question
Density = 1.122 g/L
volume = 125 mL
We must convert the volume from mL to L
1000 mL = 1 L
125 mL = 0.125 L
volume = 0.125 L
Substitute the values into the above formula and solve for the mass
That's
mass = 1.122 × 0.125 = 0.14025
We have the final answer as
<h3>0.14 g</h3>

Answer:
f = 6 × 10^15 Hz in the ULTRAVIOLET (UV) region
Explanation:
Using λ = v/f
Where;
λ = wavelength (m)
v = speed of light (3 × 10^8m/s)
f = frequency (Hz)
According to this question, λ = 5.00 x 10^-6 cm
= 5.00 x 10^-8 m
λ = v/f
f = v/λ
f = 3 × 10^8 ÷ 5.00 x 10^-8
f = 0.6 × 10^(8+8)
f = 0.6 × 10^16
f = 6 × 10^15 Hz
In the electromagnetic spectrum (EM), a frequency of 10^15 is found in the ULTRAVIOLET region. This means that this radiation with a wavelength of 5.00 x 10^-6 cm and frequency of 6 × 10^15 Hz is in the ULTRAVIOLET region of the EM spectrum.
80ºF.
Explanation:
At a temperature of 80ºF, the milk has the highest thermal energy.
The thermal energy in a body increases as the temperature of the body increases.
To increase the temperature of a body, heat is a supplied to it or work is done on it.
- Heat is a form of thermal energy.
- As the heat increases, the particles of the milk gains more kinetic energy.
- This forces them to move more faster.
- A body with a higher temperature has more thermal energy.

Answer:
Stalagmites
Sinkholes
Stalacites
Explanation:
These features are created because the ground water dissolves solid rocks and move the solid rocks, dissolve solutions beneath the ground water gradually and therefore enlarging the cracks, which eventually form a cave. Ground water carries minerals which are then deposited and can form stalagmites or stalactites. If a stalactite and stalagmite combine together, they usually form a column.
