vacuum walls: prevents heat loss by comduction and radiation
silvered walls prevent loss by radiation
ceramic base prevents loss by conduction
cap prevents by radiation and convection and reduces by comduction
Answer:
distance is how far away something has travelled from another object, while displacement is how far something is from the other object. Displacement is a vector quantity, unlike distance.
784 Newton ( mass x gravity = 80 x 9.8)

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.
