Answer:

The answer is

A. Switch

Explanation:

A switch is a device for making and breaking current in an electric circuit, it is mostly made of a non conducting material to prevent the user from being electrocuted, switches comes in range of types depending on the area of applications.

vampirchik [111]

Answer:

Plausible deniability.

Explanation:

Plausible deniability.

It is the ability of a person to refuse to accept knowledge of responsibility, if any secret(demeaning) action is done by others in an organizational hierarchy as there may be lack of evidence to confirm their involvement. Specially for high level official who can willfully deny any awareness of the to avoid themselves getting involved in blame game.

A machine has a velocity ratio of 6 and is 80%efficient. What effort would be needed to lift a load of 300N with the aid of this
valkas [14]
Efficiency =Velocity Ratio/Mechanical Advantage *100%

80%=6/MA*100%
Therefore MA=7.5

MA=Load/Effort
7.5=300/E
E=300/7.5
E=40

An arrow is launched upward with an initial speed of 100 meters per second (m/s). The equations above describe the constant-acce
BigorU [14]

Answer:

510 m

Explanation:

The arrow is fired upward, so the motion of the arrow is a free fall motion, therefore we can find the maximum height by using the suvat equation

v^2-u^2=2as

where

v is the final velocity

u is the initial velocity

a is the acceleration

s is the displacement

Here we have:

v = 0 (at the point of maximum height, the velocity of the arrow is zero)

u = 100 m/s (initial velocity)

a=g=-9.8 m/s^2  (acceleration of gravity, downward)

s = ? is the maximum height

Solving for s,  we find the maximum height of the arrow:

s=\frac{v^2-u^2}{2a}=\frac{0-100^2}{2(9.8)}=510 m
