Answer:
According to the scientists, evidence of an underground ocean suggests that Enceladus is one of the most likely places in the solar system to "host microbial life". Emissions of water vapor have been detected from several regions of the dwarf planet Ceres.
Explanation:
Answer: The given statement is false.
Explanation:
Heat flux is defined as the flow of heat or energy per unit time in per unit area. S.I. unit of heat flux is watts per square meter.
Heat flux is represented by the symbol 
.
So, it means heat flux is not measured in watts only as it includes per unit area also.
Therefore, we can conclude that the given statement heat flux, or the rate of heat transfer per unit area, is measured in watts (Watts) only, is false.
Answer:
The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.
Explanation:
Given data:
Wavelength of x-ray = 8.82 nm
frequency of x-ray = ?
Solution:
speed = Wavelength × frequency
frequency = speed / Wavelength
c = 3 × 10⁸ m/s
f = c/ λ
f = 3 × 10⁸ m/s /8.82 × 10⁻⁹m
f = 0.340 × 10¹⁷ s⁻¹
The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.
