Answer:

\huge\boxed{\sf F= 350 \ N}

Explanation:

Considering pivot as the central point,

<u>Key:</u>

  • Torque = Force F × radius r
<h3>Anticlockwise torque = Clockwise torque</h3>

F_1r_1=F_2r_2

Here,

  • Anticlockwise force is F
  • Clockwise force is 600 N
  • r_1=70+50= 120 \ cm = 1.2 \ m
  • r_2=70 \ cm = 0.7 \ m
<h3><u>Solution:</u></h3>

Substitute the givens in the above formula.

F(1.2)=600(0.7)\\\\F(1.2)=420\\\\Divide \ 1.2 \ to \ both \ sides\\\\F=420/1.2\\\\F= 350 \ N\\\\\rule[225]{225}{2}

Compare the magnitude of the electromagnetic and gravitational force between two electrons separated by a distance of 2.00 m. As
Lesechka [4]
First you need to know about two laws, which are:
1) Coulomb's law
2) Newton's law of gravitation

1.
According to Coulomb's law, Electric force between TWO charges is:
F_{e} =  \frac{k*q_{1}*q_{2}}{r^{2}} -- (A)

Where, k = 1/(4*π*epsilon_not) = 9 * 10^{9} \frac{Nm^{2}}{C^{2}}

Both q_{1} and q_{2} = -1.61 x 10^{-19} C
r = Distance between the two charges = 2.00m

Plug-in the above values in (A), you would get:

F_{e} = (9 * 10^{9} ) (1.61 * 10^{-19}  * 1.61 * 10^{-19}) / (2*2)  

F_{e} = 5.83* 10^{-29} N

2.
According to Newton's law of gravitation:
F_{g} =  \frac{Gm_{1}m_{2}}{r^{2}} -- (B)

Where G = Gravitational constant = 6.674 * 10^{-11} m^{2} kg^{-1}s^{-2}

m1 = m2 = Mass of the electron = 9.11 * 10^{-31} kg
r = 2.0 m

Plug-in the above values in (B), you would get:

F_{g} = (6.674 * 10^{-11}) ( 9.11 * 10^{-31}  *  9.11 * 10^{-31}}[/tex]) / (2*2)  

F_{e} = 5.83* 10^{-29} N

F_{e} = 1.38 * 10^{-71} N

Now do Fe over Fg, you would get:
\frac{F_{e}}{F{g}}  = 4.23 * 10^{42}

Ans: So the blanks are:
1) 5.82
2) 1.38
3) 4.23

What factors will increase the amount of energy by kinetic
marissa [1.9K]

Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another inside a gravitational field, the force of gravity will do positive work on the object and the gravitational potential.

If raindrops are falling vertically at 8.30 m/s, what angle from the vertical do they make for a person jogging at 2.07 m/s?
dmitriy555 [2]

Answer:

∆ = 14°

Explanation:

Let the angle be ∆

Opposite = 2.07 m/s

Adjacent = 8.3 m/s

Tan ∆ = opposite / adjacent

Tan ∆ = 2.07 / 8.3

Tan ∆ = 0.2494

∆ = ArcTan (0.2494)

∆ = 14°

The angle from vertical the raindrops make for a person jogging is 14°

In the roman soldier model for refraction, a muddy stream crosses the road they are on walking on at 45. Will the soldiers in th
Mamont248 [21]

There are different refractive errors that are common and some of them are:

  • Nearsightedness (myopia) makes far-away objects look blurry.
  • Farsightedness (hyperopia) makes nearby objects look blurry.
  • Astigmatism can make far-away and nearby objects look blurry or distorted.
  • Presbyopia makes it hard for middle-aged and older adults to see things up close

<h3>What is Refraction?</h3>

This refers to the study of light phenomena that deflects when it passes through a medium in an oblique manner to another medium of a varying density.

Hence, we can see that there are everyday examples of refraction in simple terms which occurs and some of them are:

  • Glass
  • Human eyes
  • Ice crystals
  • Pickle jar
  • Microscope, etc.

Hence, we can see that your question is incomplete, so I gave you a general overview to help you get a better understanding of the concept of refraction.
