Answer:
<h3>
If we add impurity into a matter then elasticity</h3><h2>May change</h2>
Explanation:
When we add impurity into a matter then elasticity of the substance increases.
Answer:
Explanation:
F = GmM/d²
As gravity force is proportional to the inverse of the square of the distance,
doubling the distance will reduce the weight to a forth.
F' = GmM/(2d)²
F' = ¼GmM/d²
F' = ¼F = ¼(4000)
F' = 1000 N
To solve this problem it is necessary to apply the concepts related to linear momentum, velocity and relative distance.
By definition we know that the relative velocity of an object with reference to the Light, is defined by
Where,
V = Speed from relative point
c = Speed of light
On the other hand we have that the linear momentum is defined as
P = mv
Replacing the relative velocity equation here we have to
Therefore the height with respect the observer is
Therefore the height which the observerd measure for her is 0.56m
Answer:
12.24 m/s
Explanation:
Speed: This can be defined as the rate of change of distance with time. The S.I unit of speed is m/s.
Using the formula,
a = v/t................ Equation 1
Where a = acceleration of the sprinter, v = speed of the sprinter, t = time.
making v the subject of the equation,
v = at ................. Equation 2
Given: a = 5.1 m/s², t = 2.4 s.
Substitute into equation 2
v = 5.1(2.4)
v = 12.24 m/s.
Hence, the speed of the sprinter = 12.24 m/s
Increase in frequency over time until they reach fixation, replacing the ancestral allele in the population
