Dominant genes and recessive genes are both given to a parents offspring. However, not both can be expressed causing the difference of dominant and recessive. Dominant genes are more likely to be expressed and recessive genes are more likely to be repressed.
Answer:
707 m/s
Explanation:
Since the root mean temperature is directly proportional to the root mean square velocity.
We have
V1/V2 =√T1/T2
V1= root mean square velocity of nitrogen at 300K
V2= root mean square velocity of nitrogen at 600K
Thus;
517/V2 = √300/600
517/V2 = 0.707
V2 = 500/0.707
V2= 707 m/s
Answer:75m
Explanation: simple kinematics . xo=0 , vo=0
x=xo+vo*t +at*t/2 = 6*5*5/2 =75m
Answer:
Cycles per second is dependent on the construction of the alternator and the 120 volts is dependent upon the current and resistance in the circuit according to the ohms law.
Explanation:
We are given with AC of 120 volts, 20 amperes and 60 hertz frequency.
<u>According to the Ohm's law, we find its resistance:</u>
So, this 6 ohm resistance controls the current controls the magnitude of the AC current, while the frequency of the current remains constant and depends upon the construction and rotational speed of the armature of the alternator producing the current.
Here the value of frequency is the number of times the current changes its direction or the polarity in one second.
