The bat hits the baseball forward. The baseball hits the bat backwards.

The bee hits the windshield northward./The windshield hits the bee southward

Explanation:

Newton's third law states that:

"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"

It is important to note that the action force and the reaction forces act on the same pair of objects.

Let's now analyze each case:

- The earth pulls down on the chair./The ground pushes up on the chair.  --> NO. The correct pair would be: The earth pulls down on the chair / the chair pulls up on the earth (in fact, the chair exerts a gravitational force on the Earth as well, pulling upward)

- The bat hits the baseball forward. The baseball hits the bat backwards.  --> TRUE. This is an example of action/reaction force pair.

- The boy pushes rightward on the box./Friction resists the motion leftward on the box.  --> FALSE. The correct pair would be: The boy pushes rightward on the box / the box pushes leftward on the boy

- The bee hits the windshield northward./The windshield hits the bee southward.  --> TRUE. This is an example of action/reaction force pair.

The rope pulls the box upward./The earth pulls the box downward. --> FALSE. A correct pair would be: the rope pulls the box upward / the box pulls the rope downward.

What will happen and give a reason
djyliett [7]

Answer:

1 or 2 or 3

Explanation:

it depends whether the coat is a light or dark colour. if it is lighly coloured it will not absorb heat from the sun and wont melt the snowman. if it is darkly coloured it will be number 1

the coat wont make a difference if the temperature of the snowman is the same and the temperature outside the snoman and the sun isnt shining. the coat would just make him look smart - so number 2

it coul keep in the cold and block out the warmth so number 3

Nuclear energy can be used to power _______.
hoa [83]
<span>Nuclear power plants produce radioactive waste that must be stored properly. It is very impossible for a nuclear power plant to have no waste at all since lots of chemicals are used to create the process as it gives energy to other machines. Nuclear energy can be used to power all of the above choices. Radioactive waste can not be released into local water supplies since the wastes are very radioactive and may cause mutation to the fishes and bioaccumulation which will affect humans as well. It will also cause air pollution if the chemicals are not stored properly.</span>

The Pacific Plate is moving 29 mm/year toward the north and 20 mm/year toward the west relative to the North American Plate. Sho
adell [148]

Answer:

7 mm per year

Explanation:

It is given that :

The Pacific plate is moving towards north at = 29 mm per year

The Pacific plate is moving towards west at = 20 mm per year

We have to calculate the total relative motion towards the northwest.

So we have to find the resultant of the two motions.

Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.

Therefore, finding their resultant,

R^2=(29)^2+(20)^2

R^2=(49)^2

R = 7

Therefore, total relative motion towards the northwest is 7 mm per year.

ASHA 777 [7]

Answer:

a=2.304×10¹⁶m/s²

Explanation:

Given data

Distance d=2.5 nm=2,5×10⁻⁹m

Mass of proton m=1.6×10⁻²⁷kg

charge of proton q=1.6×10⁻¹⁹C

To find

acceleration a

Solution

Apply the Coulombs Law

F=k\frac{q_{1}q_{2}  }{r^{2} }

Where k is coulombs constant (k=9×10⁹Nm²/C²)

q=q₁=q₂

r=d

So

F=k\frac{|q^{2} |}{d^{2} }\\ as \\F=ma\\ma=k\frac{|q^{2} |}{d^{2} }\\a=\frac{k}{m} \frac{|q^{2} |}{d^{2} }\\a=\frac{(9*10^{9} )*(1.6*10^{-19} )^{2} }{(1.6*10^{-27} )*(2.5*10^{-9} )^{2} }\\ a=2.304*10^{16}m/s^{2}
