Answer:

FALSE.

Explanation:

Newton's third law states that :

Every action has equal and opposite reaction
That is , the magnitude is the same but the directions are opposite
The action reaction forces DONOT operate on the same body.

For example ,

If a block is kept on the ground , the action force is the normal force acting on it due to the ground. BUT , NOTE THAT : the reaction force isn't the gravitational force on the body ! It is the normal force acting on the ground due to the block !

Thus,

we conclude that action and reaction forces donot act on the same body and therefore , this case has the answer : FALSE

Unless otherwise posted, what is the speed limit in a school zone? florida

Naya [18.7K]

The speed limit in the school zone in Florida may not be less than 15 miles per hour excluding the local directive. No school zone speed limit intends to be more than 20 miles per hour in an urbanized zone as well-defined in section 334.03. The speed limit may possibly in force only all through those times 30 minutes before or during and 30 minutes after the periods of time when pupils are incoming at a regularly organized school session. Stable signs labeling school zones and school zone speed limits shall be identical in size, color and shall have the times all through which the restraining speed limit is compulsory clearly designated thereon.

Which is an important step in how an electric motor uses magnetic force to produce motion?

Romashka [77]

The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. Hope this helps. Have a nice day. Feel free to ask more questions.

How many electrons must be removed from each of two 4.85-kg copper spheres to make the electric force of repulsion between them

VladimirAG [237]

Answer:

$n=2.611*10^{9}electrons$

Explanation:

Given data

mass of copper m=4.85 kg

charge of electron qe= -1.6×10⁻¹⁹C

To find

Number of electron n must be removed

Solution

Equate the magnitude of electric force Fe of repulsion between two two spheres to the magnitude of gravitational force of attraction between them

$F_{e}=F_{g}\\ k\frac{q_{e}q_{e}}{r^{2} }=G\frac{m^{2} }{r^{2} }\\ k(q_{e})^{2}=Gm^{2}\\$

where q is charge of each sphere which is equal to number n of removed electrons multiplied by each charge qe

$k(nq_{e})^{2}=Gm^{2}\\n=\sqrt{\frac{Gm^{2}}{k(q_{e})^{2}} }\\ n=\sqrt{\frac{(6.67*10^{-11}N.m^{2}/kg^{2})(4.85kg)^{2}}{(8.99*10^{9}N.m^{2}/C^{2} )(1.6*10^{-16}C)^{2}} }\\n=2.611*10^{9}electrons$

As an object is undergoing free fall motion.As it falls the objects?,speed increases,acceleration increases,both of these,or non

Alex_Xolod [135]

The speed will increase, as there is acceleration, while the acceleration will remain constant, as gravity is constant.
