Answer:
The machine-gun was one of the deadliest weapons of the Western Front, causing thousands of casualties. It was a relatively new weapon at the start of the war, but British and German forces soon realised its potential as a killing machine, especially when fired from a fixed defensive position.
The Vickers machine-gun (above) was famed for its reliability and could fire over 600 rounds per minute and had a range of 4,500 yards. With proper handling, it could sustain a rate of fire for hours. This was providing that a necessary supply of belted ammunition, spare barrels and cooling water was available. When there was no water to hand, soldiers would urinate in the water jacket to keep the gun cool!
Explanation:
Answer:
So reservoir will take 455000 sec to raise 35 cm
Explanation:
We have given surface area of the reservoir = 650000 
Rate of flow = 0.5 m/sec
Height through which reservoir is raise = 35 cm = 0.35 m
So volume 
We have to calculate the time
Time is given by 
Answer:
When it rains, rainwater soaks into the ground and puts pressure on the existing water in the ground, forcing some of it to move through natural cracks and openings in the rock until it reaches the surface and forms a(n) spring.An underground layer of permeable rock that is situated between two layers of impermeable rock so that water is trapped within it is called a(n) confined aquifer.
Explanation:
I did it on Edge2020
<span>Faunal succession recognized in the sequence of fossils in stratified sedimentary rocks was a key concept that led to the concept of evolution of life on Earth</span>. T<span>his principle is from Willian Smith, an English geologist. It used to determine the age of the rocks and strata.</span>
650 × 16 = 10400
10400 ÷ 100 = 104
<u>So the answer is 104</u>
