Answer:
The speed of the stone is
v = 7.45 m/s
Explanation:
Length, L=0.551m
maximum tension in the spring = 9.6%
So let speed of stone be
Tv = TH + 9.6/ 100 * TH
Tv - m*g = m*v^2/L
TH = m*v^2 / L
Factor mass to cancel in the equation
Solve to v
v^2= L*g*100 / 9.6
Replacing numeric:
v^2=0.551m*9.8m/s^2*100 / 9.6
v = sqrt( 56.24 m^2/s^2)
v = 7.45 m/s
The Huygens<span>-Fresnel </span>principle<span> states that every point on a wavefront is a source of wavelets. These wavelets spread out in the forward direction, at the same speed as the source wave. The new wavefront is a line tangent to all of the wavelets. </span>
Work or energy spent=force times distance=25N*4m=100Nm
power=energy or work divided by time=100Nm/5s=20Nm/s
Based on the principles of heredity, some common medical conditions with a family history include hypertension, hemophilia, shortsighted ness, diabetes, etc.
<h3>What is a family history of a medical condition?</h3>
A family history of a medical condition is a detailed history of members of a family who suffer from a particular disease of a medical condition.
Since characters are passed on from parents to offspring, sometimes certain diseases too are passed on from parents to offspring.
For example, a family may have a history of hypertension, this disease may be due t a defect in a gene, thus, all the offspring in that family who inherit this defect will suffer from the disease.
Other diseases that may be in a family include, hemophilia, shortsighted ness, diabetes, etc.
In conclusion, diseases that are found in a family occur due to the principles of heredity.

Answer:
The incidence angle is 0.145°.
Explanation:
Given that,
Distance due to east = 119 m
Distance due to north= 47.0 km
We need to calculate the incidence angle
Using formula of incidence angle
Where, y = distance due to north
x = distance due to east
Put the value into the formula
Hence, The incidence angle is 0.145°.
