Answer:
i think it Naturalistic observation
Explanation:
A uniform metal rod with of length 80cm and a mass of 3.2kg is supported horizontally by two vertical spring balances C and D. Balance C is 20cm from one end while D is 30cm from the other end would show the reading of 1.06 Kg and 2.13 kg respectively
<h3>What is gravity?</h3>
It can be defined as the force by which a body attracts another body towards its center as the result of the gravitational pull of one body and another, The gravity varies according to the mass and size of the body for example the force of gravity on the moon is the 1/6th times of the force of gravity on the earth.
As given in the problem, A uniform metal rod of the length of 80cm and mass of 3.2kg is supported horizontally by two vertical springs balance C and D. Balance C is 20cm from one end while D is 30cm from the other end
The weight of the rod acting downward is from the center of the rod at 40 cm
Let us suppose the reading on the spring balance C and D are P and Q respectively
By using the equilibrium for the vertical force
Fv=0
P + C = 3.2
By using the equilibrium for the moment around the left corner
20×P+ 50×Q= 40 ×3.2
By solving for both P and Q from the above two equations we would get
P =1.06 and Q = 2.13
Thus, the reading on the spring balance C and D would be 1.06 Kg and 2.13 kg respectively

Answer:
The force will be 
Explanation:
Let's use the centripetal force equation.
Where:
m is the mass of the bunch of bananas
ω is the angular speed
R is the radius
Now, 1 rev every 4 seconds or 0.25 rev/sec is the angular speed, but we need to write this speed in rad per second.
FInally, the force will be:

Answer:
Explanation:
Let the allele for dark color be represented by "D" and the allele for light color be represented by "d"
Also D is dominant over d
Similarly, let the allele for obese trait in mice be represented by "O" and the allele for lean trait in mice be represented by "L"
Obese and lean exhibit incomplete dominance
Genotype of true breeding dark and obese mice be DDOO
Genotype of true-breeding lean and light mice is ddLL
Offspring from F1 cross -
DdOL
F2 cross is between DdOL * DdOL
DO DL dO dL
DO DDOO DDOL DdOO DdOL
DL DDOL DDLL DdOL DdLL
dO DdOO DdOL ddOO ddOL
dL DdOL DdLL ddOL ddLL
dark and intermediate between obese and lean offspring genotype –
2 DDOL, 4 DdOL
So total six out of sixteen offspring are dark and intermediate between obese and lean -
Answer:
Efficiency can be increase by using rollers in conjunction with the inclined plane. Wedge. The wedge is an adaptation of the inclined plane. It can be used to raise a heavy load over a short distance or to split a log
