This question comes along with four answer choices:
a) the thermal energy moving from the coffee to her tongue
b) the thermal energy moving from her tongue to the coffee
c) her coffee
d) her tongue
Answer: a) the thermal energy moving from the coffee to her tongue.
Explanation:
Heat, heat energy and thermal energy are terms to refer the same thing.
Heat is the kinetic energy of the molecules or particles in a substance wich is transferred from hot substances to cool substances.
In the example, the coffe is hot and Ixchelt's tongue is cool, so the heat is the thermal energy transferred from the hot coffe to Ixtchel's tongue.
The thermal energy (heat) always flows from the hot to the cold, never the other way around.
Answer:
A
Explanation:
A is the answer
The wavelength of the radio wave is 5.5 × 10³ m. If the frequency of the wave is 5.5 × 10⁴ hertz and the speed of the wave is 3.0 × 10⁸ m/sec.
The speed(v) of a wave is the product of wavelength(λ) and the frequency(η). We can understand this relation by the definition of the speed, which is the distance travelled by the object in unit time. The unit of distance is meter, also the unit of the wavelength is meter. On the other hand the unit of frequency is sec⁻¹. So,
Speed of a wave(v) = wavelength(λ) × Frequency(η)
Wavelength(λ) = speed of the wave(v)/Frequency(η)
Wavelength(λ) = (3.0 × 10⁸)/(5.5 × 10⁴)
Wavelength(λ) = 5.5 × 10³ m
