An LED lightbulb has an efficiency of 11,5% and a power of 10 W. How much

Biology

The light bulb produces 1.15 J  energy in 1 second.

<u>Explanation:</u>

Efficiency of an electric appliance is defined as the ratio of output power to the input power. In a 100% efficient appliance all of the input power will be converted to output power. In the given question  it is given that

input power= 10W  

efficiency= 11.5%

(output power)/(input power)=efficiency  

output power = input power * efficiency

=10 \times (11.5/100)=1.15W

Now we have to calculate the energy produced by the light bulb in 1 second

energy=power \times time

=1.15 \times 1

=1.15J

Answer:

27:9:9:9:3:3:3:1

Explanation:

The gametes of the parental genotypes would be  

ABC, ABc, AbC, aBC, Abc, aBc, abC, abc

The cross between AaBbCc and AaBbCc will result into following offspring  (image is also attached)

        ABC        ABc           AbC   aBC         Abc     aBc abC abc

ABC AABBCC       AABBCc AABbCC   AaBBCC AABbCc AaBBCc AaBbCC AaBbCc

ABc AABBCc AABBcc AABbCc AaBBCc AaBbcc AaBBcc AaBbCc AaBbcc

AbC AABbCC AABbCc AAbbCC AaBbCC AAbbCc AaBbCc AabbCC AabbCc

aBC AaBBCC AaBBCc AaBbCC aaBBCC AaBbCc aaBBCc aaBbCC aaBbCc

Abc AABbCc AABbcc AAbbCc AaBbCc AAbbcc AaBbcc AabbCc Aabbcc

aBc AaBBCc AaBBcc AaBbCc aaBBCc AaBbcc aaBBcc aaBbCc aaBbcc

abC AaBbCC AaBbCc AabbCC aaBbCC AabbCc aaBbCc aabbCC aabbCc

abc AaBbCc AaBbcc AabbCc aaBbCc Aabbcc aaBbcc aabbCc aabbcc

The genotype ratio is 27:9:9:9:3:3:3:1
