The correct answer is A. Action and reaction forces

Explanation:

Isaac Newton was an important English physicist, astronomer, and mathematician mainly known in the field of physics for his tree laws related to motion. In the case of the third law, this law states every action of movement implies a reaction that is expressed as an opposite force in equal magnitude that acts against the first object that is moving, for example when you push an object there with your hand is a first force you apply to the object you are pushing, but also the object applies an opposite proportional force in your hand which shows action and reaction forces. Therefore Newton's third law of motion describes action and reaction forces.

A beam of light with a wavelength 760 nm in air travels in water. The index of refraction of water is 1.33. What is the waveleng
BabaBlast [244]

Answer:

<em>The wavelength of water = 571.43 nm</em>

Explanation:

Refractive index of water = wave length of light in air/wave length of light in water

R.d = λ₁/λ₂.................. Equation 1

making λ₂ the subject of equation 1

λ₂ = λ₁/R.d...................... Equation 2

R.d = refractive index of water , λ₁ = wave length of light in air, λ₂ = wave length of light in water

<em>Given: R.d = 1.33, λ₁ = 760nm</em>

<em>Substituting these values into equation 2</em>

λ₂  = 760/1.33

<em>λ₂  = 571.43 nm</em>

<em>Therefore the wavelength of water = 571.43 nm</em>

A brass washer has an outside diameter of 4.50 cm with a hole of diameter 1.25 cm and is 1.50 mm thick. The density of brass is
-Dominant- [34]
We will find the mass from 
mass = density x volume 
We are told the density and must find the volume from the dimensions given 
the volume of the washer will be the area x thickness (remembering to convert all measurements to meters) 
if the washer had no hole, its area would be pi (0.0225m)^2 (remember to convert to meters and to use radius) 
the area of the hole is pi(0.00625m)^2 
so the area of the washer is pi[(0.0225m)^2 - (0.00625m)^2] = 1.5x10^-3 m 
the volume of the washer is 1.5x10^-3 m x 1.5x10^-3 m = 2.25x10^-6 m^3 (the thickness of the washer is 1.5 mm = 1.5x10^-3m) 
thus, the mass of the washer = 8598kg/m^3 x 2.25x10^-6m^3 = 0.0189kg = 18.9 grams

Susan's 12.0 kg baby brother Paul sits on a mat. Susan pulls the mat across the floor using a rope that is angled 30∘ above the
Pavlova-9 [17]

Answer:1.71 m/s

Explanation:

Given

mass of Susan m=12 kg

Inclination \theta =30^{\circ}

Tension T=29 N

coefficient of Friction \mu =0.18

Resolving Forces Along x axis

F_x=T\cos \theta -f_r

where f_r=friction\ Force  

F_y=mg-N-T\sin \theta

since there is no movement in Y direction therefore

N=mg-T\sin \theta

and f_r=\mu N

Thus F_x=T\cos \theta -\mu N

F_x=29\cos (30)-\0.18\times (12\times 9.8-29\sin (30))                

F_x=25.114-18.558

F_x=6.556 N

Work done by applied Force is equal to change to kinetic Energy

F_x\cdot x=\frac{1}{2}\cdot mv_f^2-\frac{1}{2}\cdot mv_i^2

6.556\times 2.7=\frac{1}{2}\cdot 12\times v_f^2

v_f^2=\frac{6.556\times 2.7\times 2}{12}

v_f^2=2.95

v_f=1.717 m/s

An object with mass M is attached to the end of a string and is raised vertically at a constant acceleration of g 10 . If it has
RoseWind [281]

Answer:

Work done against gravity will be

W = Mgℓ

Explanation:

Work done to raise the mass from ground to given height is against gravity

So here work done is given by the formula

W = F.d

here we know that

F = Mg

it is the force due to gravity which is also known as weight

so here distance moved by the object is given as

d = ℓ

now work done is given as

W = Mg ℓ
