First off how is it automation, when the person who asked the question just said “when people REPLACE systems.” Automation is like the use of systems and machines. The person answered automation which is the toatal opposite of the answer, which is C, Manual labor. Manual labor is where humans work instead of the machines/systems.

So in simpler words......C.
Have a great day!

Please help!!!

V125BC [204]

Answer:C

Explanation:

For every action or force there is an equal and opposite reaction or force

So the force on the bat is the same as the force on the ball but in opposite directions

Now the ball will fly farther but that is a different law

Prior to science lab, Maria had been drinking a can of soda. When she walked into the lab she set it down on the hot plate at he

Vesnalui [34]

Answer:

The hypothesis as to what happened to the soda and the air in the can are as follows;

The solubility of air in the soda is high at low temperatures, such that air (carbon dioxide, CO₂) is trapped in the soda and when it is drank, it gives it its fresh taste

By placing the can of soda on the hot plate, drives off the air in the soda such that the space directly above the liquid soda is filled with the original air (carbon dioxide), in the soda

By dipping the soda upside down in the sink half filled with water, the soda is cooled down and the air (carbon dioxide) directly above the surface of the liquid soda is reabsorbed into the liquid soda, such that if the lid of the soda is sealed, the vacuum created by the empty space directly above the liquid soda becomes a region of low pressure and the combined pressure from the atmosphere and the liquid level in the sink, causes the can to immediately crushed (deformed).

A proton is traveling horizontally to the right at 1.8 × 106 m/s. (a) Find the magnitude and direction of the weakest electric f

Mars2501 [29]

Answer:

528398.4375 N/C opposite to the direction of the proton

$3.56\times 10^{-8}\ s$

288.24609375 N/C in the same direction of the motion of the electron

Explanation:

t = Time taken

u = Initial velocity = 0

v = Final velocity = $1.8\times 10^{6}\ m/s$

s = Displacement = 3.2 cm

a = Acceleration

Mass of electron = $9.11\times 10^{-31}\ kg$

Mass of electron = $1.67\times 10^{-27}\ kg$

q = Charge of particle = $1.6\times 10^{-19}\ C$

$v^2-u^2=2as\\\Rightarrow a=\dfrac{v^2-u^2}{2s}\\\Rightarrow a=\dfrac{0^2-(1.8\times 10^6)^2}{2\times 0.032}\\\Rightarrow a=-5.0625\times 10^{13}\ m/s^2$

Electric field is given by

$E=\dfrac{ma}{q}\\\Rightarrow E=\dfrac{1.67\times 10^{-27}\times -5.0625\times 10^{13}}{1.6\times 10^{-19}}\\\Rightarrow E=−528398.4375\ N/C$

The electric field is 528398.4375 N/C opposite to the direction of the proton

$v=u+at\\\Rightarrow t=\dfrac{v-u}{a}\\\Rightarrow t=\dfrac{0-1.8\times 10^6}{-5.0625\times 10^{13}}\\\Rightarrow t=3.56\times 10^{-8}\ s$

The time taken is $3.56\times 10^{-8}\ s$

$E=\dfrac{ma}{q}\\\Rightarrow E=\dfrac{9.11\times 10^{-31}\times -5.0625\times 10^{13}}{-1.6\times 10^{-19}}\\\Rightarrow E=288.24609375\ N/C$

The electric field is 288.24609375 N/C in the same direction of the motion of the electron
