How did new technology in WW1 change the way battles were fought

<span>Before i get into technology. This is the ammount of deaths a war (other then the American Civil War) would have had before WW 1, around 50,000-200,000. World War 1 had almost 11 million deaths. Since WW 1 proposed new machine guns that were smaller and faster and could hold much more bullets then the earlier machine guns, it could take a load of lives. Because of the machine guns, the soldiers had to "dig in" (dig trenches and stay there) to avoid the machine gun fire. When the Germans launched chemical warfare in 1915 with Chlorine Gas, the average WW 1 soldier started to have to carry around a gas mask. In 1916 when France and Britain started using tanks, the trenches of WW 1 started to be deaper, and have huge mounds built around them to stop the tanks from advancing. When scouting air planes began to become bombers, other planes started to have to have machine guns built on them to stop the planes from bombing, thus the dog fights (airplanes fighting in the sky) were born.</span>

Answer: B) Elaborative rehearsal

Explanation: Elaborative rehearsal is the technique through which a term is recalled or remembered along with its meaning to create a connection with something an individual knows about that term.It is considered as the effective method for memorizing the terms for long period of time. It can be done by viewing images, example etc.

According to the mentioned scenario, Jeremy is using the elaborative rehearsal technique for remembering the concept examples so that he can remember the theory in deep manner for long duration.

Other options are incorrect because serial position effect is used for recalling term in series from first to last. Contextual cue are termed as environmental aid for memory and maintenance rehearsal involves continuous thinking for recalling the term.Thus, the correct option is option(B).

A basketball is dropped from the edge of a cliff at the same time that second basketball is thrown upward from the ground. When

pentagon [3]

Answer:

The collision occurs at a height of 1/3 of the total height of cliff.

Explanation:

The situation is represented in the attached figure:

For the stone dropped from top of cliff we have

Initial velocity of drop= 0 m/s.

Now the time at which it attains a velocity of 2v is obtained from first equation of kinematics as

$v_{f}=u_{i}+gt\\\\2v=0+gt\\\\\therefore t=\frac{2v}{g}$

Thus the distance it covers in this time can be calculated using third equation of kinematics as

$v_{f}^{2}=v_{i}^{2}+2gh\\\\(2v)^{2}=2gh_{1}\\\\\therefore h_{1}=\frac{2v^{2}}{g}$

For the stone thrown upwards the velocity at collision is give as 'v' thus the velocity at which it is thrown upwards can be calculated by first equation of kinematics as

$v=v_{i}-gt\\\\\therefore v_{i}=v+gt\\\\v_{i}=v+g\times \frac{2v}{g}\\\\\therefore v_{i}=3v$
