Answer:
Width w = 4m
Glow depth = y1 = 20m
Outlet discharge = 40m
V1= velocity of flow = 40/20*4 = 1/2 = 0.5m/s
Froud number = v1/√gy1
= 0.5/√9.81x20 = 0.0356
1. Y2/20 = 1/2[-1+√1+8*(0.0356)²]
Y2 = 0.05
2. Energy loss in the jump = (20-0.05)²/4x20x0.05
= 1985m
Answer:
He probably tripped the wiring, when metal hits the electricity it creates a reaction that burns the wiring.
Explanation:
Answer: c) they have low genetic variability among them.
When a plant is grown for several generations of offspring of a plant, then there are some common things which are to be noted which are found similar in the offspring and in the parent of the offspring. The flowers and fruits and the time or season they come in are absolutely the same.
Answer:
Smaller impurity atom will nullify some of the compressive strain of a dislocation in a crystal. Because, smaller impurity atoms located near a dislocation creates tensile strain on atoms around it thereby partially nullifying compressive strain at the dislocation.
Answer:
The correct option is d ( Neither A nor B)
Explanation:
Technician A made 2 mistakes in his statement.Firstly the tire is self supporting not self sealing.
Secondly, this tire does not provide permanent sealing of punctured area option a is incorrect.
This self-supporting tire after being affected with complete air leakage can temporarily bear the load of the car and avoid rolling over a distance of 80 km at a maximum speed of 55 mph. Here is what technician B suggested incorrectly as the tire after being.Here the technician B suggested incorrectly as the tire after being affected with puncture can not travel at any speed so option B is wrong
Since option a and b are incorrect and c is invalid.
