Answer:
B.
Explanation:
Causes mutations in DNA.
The signature mutation caused by ultraviolet light is a CC to TT mutation, caused when a CC dimer is mispaired with two adenine bases during replication. Because of these mutations, the connection between ultraviolet damage to DNA and cancer is quite clear.
Answer:
Please see below as the answer is self-explanatory.
Explanation:
- In order to have a destructive interference, the path difference between the sources of the sound, must be equal to an odd multiple of the semi-wavelength, as follows:
- The minimum posible value for this distance, is when n=1, as it can be seen here:
- In any traveling wave, there exists a fixed relationship between the wave speed, the frequency and the wavelength:
- Therefore, assuming that the speed of sound keeps constant, if the frequency is increased, in order to keep the right side of the expression above balanced, λ must be decreased.
- As the smallest separation that produces destructive interference is directly proportional to the wavelength, this means that this separation will decrease if the cellists produced a note with a higher frequency.
A- 85m per second
B- 85 sdcounds
The direction of the acceleration is the same as the direction of the net force: 34 degrees. Apply the equation <eq04017> to find the magnitude of the net force, giving you 35.4 N. Use the magnitude of the force and the mass to find the magnitude of the acceleration: a = F/m = (35.4 N)/(0.10 kg) = 354 m/s2.
