Answer:
39
Explanation:
Electrons weigh almost nothing, so their mass doesn't really matter for these types of problems. Just subtract 118-79 to find the remaining mass which is for the neutrons.
Answer:
Speed of wave = 1500 m/s
Explanation:
Given data:
Frequency of wave = 10 Hz
Wavelength of wave = 150 m
Speed of wave = ?
Solution:
Formula:
Speed of wave = Frequency × Wavelength
Now we will put the values in formula.
Speed of wave = 10 Hz × 150 m
Speed of wave = 1500 m/s
Hz = s⁻¹
There is no picture or question revolving around science
The answer is B
if im wrong sorry
