Answer:
<em>L1 = WL/w</em>
Explanation:
Jacques's weight = W
Jacques's distance from the pivot = L
Gilles's weight = w
Gilles's distance from the pivot must be L1
For the two boy to balance each other, they must generate equal amount of torques around the pivot
Torque = distance x weight
For Jacques, the torque generated = WL
For Gilles, the torque generated = wL1
Balancing the two torques, we have
WL = wL1
the distance L1 must be equal to
<em>L1 = WL/w</em>

Breccia<span> and </span>conglomerate<span> are very similar rocks. They are both clastic sedimentary rocks composed of particles larger than two millimeters in diameter. The </span>difference<span> is in the shape of the large particles. In </span>breccia<span> the large particles are angular in shape, but in </span>conglomerate<span> the particles are round</span>

Given
slit width 
wavelength of light 
Screen is placed at a distance of 
The angle for the first minima is given by
for m=1
and one half of central maxima is given by
Width of central maxima 
Explanation:
a) Sum of moments about the pivot:
∑τ = Iα
(10 kg × 10 m/s²) (0.3 m) + F (-0.4 m) = 0
F = 75 N
b) Sum of moments about the pivot:
∑τ = Iα
(20 N) (0.3 m) + (20 N) (-0.2 m) + F (-0.7 m) = 0
6 Nm − 4 Nm + F (-0.7 m) = 0
F = 2.9 N
