I believe the answer would be polygenic. The word translates to "multiple genes". This occurs when many genes make up one specific thing such as our hair color or eye color.
Answer: a dark (absorption) line
Explanation:
This is as a result of absorption of electromagnetic a specific wavelength. The pattern followed by such lines is characteristic of specific atoms in the path of radiation.
Answer:
70560 m
Explanation:
The formula to calculate the distance travelled during a free fall motion is
where
d is the distance travelled
g = -9.8 m/s^2 is the acceleration due to gravity
t is the time
In this situation,
t = 120 s
Therefore the distance travelled after 120 s is
Answer:
The work done by the frictional force is 600J.
Explanation:
The work 
done by the frictional force is
.
Now, 
and 
; therefore,
Hence, the work done by friction is 660J.
Answer:
88.3
Explanation:
Emf in a rotating coil is given by rate of change of flux:
E= dФ/dt=(NABcos∅)/ dt
N: number of turns in the coil= 80
A: area of the coil= 0.25×0.40= 0.1
B: magnetic field strength= 1.1
Ф: angle of rotation= 90- 37= 53
dt= 0.06s
E= (80 × 0.4× 0.25×1.10 × cos53)/0.06= 88.3V
