Answer:
50 MHz
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Given, Wavelength = 6 m
Thus, Frequency is:
Also,
Also, 1 Hz = 
MHz
So,<u> Frequency = 50 MHz.</u>
Answer:
Organic compound
Explanation:
Acetominophen's molecular formula is C8H9NO2. Right from the formula you can also see that the compound has C (carbon) in it, therefore making it an organic compound (in which the definition is that the compound contains carbon in it).
Remembering that
d = m ÷ v
d = ?
m = 104 g
v = 21 cm³
Therefore:
d = 104 ÷ 21
<span>d = 4,95 g÷cm³</span>
Answer:
B They go through many developmental changes.
Explanation:
According to the passage, development of frogs are susceptible to minor environmental changes due to the series of developmental changes they undergo.
During the developmental phase of a typical frog, several complicated cellular differentiation cycles occurs. These cycles are connected to one another and they are triggered by certain signals and responses. Disruption in certain environmental factors can affect the various developmental changes.
