Each parent contribute 50 percent. A person have 46 genes and 23 comes from the mother and 23 comes from the father
Answer:
The box displacement after 6 seconds is 66 meters.
Explanation:
Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object (
), in meters, can be determined by the following expression:
(1)
Where:
- Initial velocity, in meters per second.
- Time, in seconds.
- Acceleration, in meters per square second.
If we know that
,
and
, then the box displacement after 6 seconds is:

The box displacement after 6 seconds is 66 meters.
Answer:
The answer is "
"
Explanation:
For point a:
Energy balance equation:


From the above equation:

because the rate of air entering the tank that is
constant.
Since the tank was initially empty and the inlet is constant hence,
Interpolate the enthalpy between
. The surrounding air
temperature:

Substituting the value from ideal gas:

Follow the ideal gas table.
The
and between temperature
Interpolate

Substitute values from the table.
For point b:
Consider the ideal gas equation. therefore, p is pressure, V is the volume, m is mass of gas.
(M is the molar mass of the gas that is
and R is gas constant), and T is the temperature.


For point c:
Entropy is given by the following formula:

<u>Answer :</u>
(a) d = 0.25 m
(b) d = 0.5 m
<u>Explanation :</u>
It is given that,
Frequency of sound waves, f = 686 Hz
Speed of sound wave at
is, v = 343 m/s
(1) Perfectly destructive interference occurs when the path difference is half integral multiple of wavelength i.e.
........(1)
Velocity of sound wave is given by :




Hence, when the speakers are in phase the smallest distance between the speakers for which the interference of the sound waves is perfectly destructive is 0.25 m.
(2) For constructive interference, the path difference is integral multiple of wavelengths i.e.
( n = integers )
Let n = 1
So, 


Hence, the smallest distance between the speakers for which the interference of the sound waves is maximum constructive is 0.5 m.
