Directly proportional to the product of the two charges and inversely proportional to the square of the distance between them
Answer:
The germline (the gametes)
Explanation:
Mutations are permanent changes in the DNA sequence. They can occur randomly, from mistakes during DNA replication, or as the result of external factors like UV radiation.
For these mutations to be passed on to the next generation, they must be present in the DNA of the gametes(i.e. the egg and sperm cells). This is because this is the DNA that goes on to make the offspring in the next generation following fertilisation.
If mutations are present in somatic cells (i.e. cells other than the gametes), they are not passed on to the next generation. For example, if someone gets mutations in their skin cells as a result of exposure to UV rays, this will not be passed on to their children.
Answer: The velocity with which the sand throw is 24.2 m/s.
Explanation:
Explanation:
acceleration due to gravity, a = 3.9 m/s2
height, h = 75 m
final velocity, v = 0
Let the initial velocity at the time of throw is u.
Use third equation of motion
The velocity with which the sand throw is 24.2 m/s.
When we say directly northeast that is equivalent
to 45˚ north of east.
First let us determine the north and east
components of the acceleration using cos and sin functions:<span>
North = 2.18 * sin 45
East = 2.18 * cos 45
<span>Then we set to determine the east component of the plane’s
displacement by calculating using the formula:
d = vi * t + ½ * a * t^2
d = 135 * 18 + ½ * 2.18 * cos 45 * 18^2
<span>d = 2430 + 353.16 * cos 45 = 2679.72 m</span>
Calculating for the north component:
North = ½ * 2.18 * sin 45 * 18^2 </span></span>
North = 249.72 m
Hence magnitude is:
Magnitude = sqrt (2679.72^2 + 249.72^2)
Magnitude = 2,691. 33 m<span>
</span>
Calculating for angle:
Tan θ = North ÷ East <span>
<span>Tan θ = 249.72 m ÷ 2679.72 m</span></span>
θ = 5.32°<span>
</span>
So the plane was flying at 2,691. 33 m at 5.32<span>°</span>
Answer:
193.4 J/K
Explanation:
For a closed system, the entropy is given as the natural logarithm of microstates.
The number of particles ( grains of sand ) N = 28
The number of boxes ( compartments ) M = 1000
Entropy is the logarithm of number of microstates
But the number of microstates is given by
