Why are “input” and “output” good words to use when discussing systems?

Answer:

Because it gives a direct relation that can be used to obtain the efficiency E = Input/output which tell us how the system works, for example, if the efficiency is bigger than one, this means that the system amplifies the input (the output is bigger than the input) while if the efficiency is less than one, the output is smaller than the input.

Where these quantities can be forces, heat, electricity, or anything.

What is true about resistance? Check all that apply. A. It is the excess accumulation of electric charge B. It is measured in oh

Alekssandra [29.7K]

Answer:

B, C and E

Explanation:

The unit of resistance in the international system is the Ohm, the equation that describes the resistance is:

$R=p\frac{l}{S} \\$

Where (l) is for lenght of the wire, (S) is the area and (p) its the constant associated to the conductor.

It's related by the Ohm's Law:

$R=\frac{V}{I}$

A jet plane is launched from a catapult on an aircraft carrier. In 2.0 s it reaches a speed of 42 m/s at the end of the catapult

Dvinal [7]

Answer:

Explanation:

Given

time taken $t=2\ s$

Speed acquired in 2 sec $v=42\ m/s$

Here initial velocity is zero $u=0$

acceleration is the rate of change of velocity in a given time

$a=\frac{v-u}{t}$

$a=\frac{42-0}{2}=21\ m/s^2$

Distance travel in this time

$s=ut+0.5at^2$

where

s=displacement

u=initial velocity

a=acceleration

t=time

$s=0+\0.5\times 21\times (2)^2$

$s=42\ m$

so Jet Plane travels a distance of 42 m in 2 s
