Answer:
H_w = 2.129 m
Explanation:
given,
Width of the weir, B = 1.2 m
Depth of the upstream weir, y = 2.5 m
Discharge, Q = 0.5 m³/s
Weir coefficient, C_w = 1.84 m
Now, calculating the water head over the weir
now, level of weir on the channel
H_w = y - H
H_w = 2.5 - 0.371
H_w = 2.129 m
Height at which weir should place is equal to 2.129 m.

Elastic potential energy is given by formula
here we know that
Now using above formula we have
So elastic potential energy in the chord is 14400 J
Answer:
width of the slit = a = 0.0935 mm
Explanation:
width of central maximum for single slit diffraction is:
----- (1)
Distance between source and screen = L = 5.5 m
Width of bright band = w = 8 cm
= 0.08 m
λ = 680 nm
Width of the slit = a = ?
Arranging (1) for a
a = 0.0935 mm
When Jeep is in motion the Canvas top is initially flat
so when Jeep is in motion the air at the top of the Jeep is in high speed
while the air inside the jeep is not moving that fast
so as per Bernuolli's Theorem we know
so if we increase the speed the pressure will decrease
so the canvas will experience less pressure at the top of canvas while at the bottom it will have more pressure from inside
so the Canvas will bulge outside or curved outside
