I would say B.) the blonde hair was a result of the expression of a recessive gene. - the dominate gene is brown hair and the recessive gene is blonde hair...hope this helps
Answer:
The coefficient of friction in the hall is 0.038
Explanation:
Given;
mass of the Parker, m = 73.2 kg
applied force on the parker, F = 123 N
frictional force, Fs = 27.4 N
the coefficient of friction in the hall = ?
frictional force is given by;
Fs = μN
Where;
μ is the coefficient of friction
N is normal reaction = mg
Fs = μmg
μ = Fs / mg
μ = (27.4) / (73.2 x 9.8)
μ = 0.038
Therefore, the coefficient of friction in the hall is 0.038
Answer:
No.
Explanation:
The force that two particle experience is inversely proportional to the sqare of the distance, this is:
for a distance D
If we move them so that D is doubled:
= 
Then the force they experience is one fourth of the original.
A higher temperature, stiffer materials, and less dense materials increase the speed of sound.
