Answer:
A)Explanation:
Let object distance be u.
Image distance v = 1.06 - u
Focal length = 20 cm = .2 m
Applying lens formula
1 / v - 1 / u = 1 / f
1 /( 1.06-u) - 1 / u = 1 / .2
5 u² -3.3u - 1.06 =0
It will have two roots
u₁ = .1636 m, u₂ = .8964 m
B ) Magnification
= u = .1636m , v = .8964m
m = .8964 / .1636 = 5.48
C ) When u = .8964m ,v = .1634m
m = .1634 / .8964
=.182
Answer: The energy incident on the solar panel during that day is .
Explanation:
Given: Mass = 250 kg
Initial temperature =
Final temperature =
Specific heat capacity = 4200
Formula used to calculate the energy is as follows.
where,
q = heat energy
m = mass of substance
C = specific heat capacity
= initial temperature
= final temperature
Substitute the values into above formula as follows.
As it is given that water absorbs 25% of the energy incident on the solar panel. Hence, energy incident on the solar panel can be calculated as follows.
Thus, we can conclude that the energy incident on the solar panel during that day is .

Answer:
x-component=-9.3 m
Magnitude of A=17.7m
Explanation:
We are given that
We have to find the x-component of A and magnitude of A.
According to question
Substitute the values then we get
m
The value of x-component of A is negative because the vector A lie in second quadrant.
Hence, the x- component of A=-9.3 m
