Answer: F = 106.72 N

Explanation: <u>Newton's</u> <u>Law</u> <u>of</u> <u>Universal</u> <u>Gravitation</u> states that two masses attract each other by a force pointing in a straight line to the center-of-mass of both masses.

It is directly proportional to the masses and inversely proportional to the square of their distance, represented as:

F=G\frac{m_{1}m_{2}}{r^{2}}

where

G is gravitational constant whose value is 6.67x10⁻¹¹ N(m/kg)²

m are masses in kg

r is distance in m

The force between the moon and a person with mass of 66kg is:

F=6.67.10^{-11}\frac{66(7.34.10^{22})}{(1.74.10^{6})^{2}}

F=\frac{3231.215.10^{11}}{3.0276.10^{12}}

F = 106.72 N

The force between a person with mass of 66kg and the moon is 106.72 N.

Which describes how the same force affects a small mass and a large mass
goldenfox [79]
You shall use the equation for force given by the second Law of Newton, this is F = m*a, where F is the net force that acts over the object, m is the mass of the object and a is the acceleration that the object will acquire. From that equation you can find a = F/m, which means that a is direct proportional to F and invsersely related to m. So, small masses accelerate faster than large masses, and <span>the answer is the option B. the small mass accelerates faster.</span>

The speed of a wave on a violin A string is 288 m/s and on the G string is 128 m/s. The force exerted on the ends of the string
Katyanochek1 [597]

Answer:

\dfrac{\mu_A}{\mu_G}=0.197

Explanation:

given,

Speed of a wave on violin A = 288 m/s

Speed on the G string = 128 m/s

Force at the end of string G  = 110 N

Force at the end of string A = 350 N

the ratio of mass per unit length of the strings (A/G). = ?

speed for string A

 v_A = \sqrt{\dfrac{F_A}{\mu_A}}.......(1)

speed for string G

 v_G = \sqrt{\dfrac{F_G}{\mu_G}}........(2)

Assuming force is same in both the string

now,

dividing equation (2)/(1)

\dfrac{v_G}{v_A}=\dfrac{\sqrt{\dfrac{F_G}{\mu_G}}}{\sqrt{\dfrac{F_A}{\mu_A}}}

\dfrac{v_G}{v_A}=\dfrac{\sqrt{\mu_A}}{\sqrt{\mu_G}}

\dfrac{128}{288}=\dfrac{\sqrt{\mu_A}}{\sqrt{\mu_G}}

\dfrac{\mu_A}{\mu_G}=0.197

A makes an angel of 30.0 above the positive x-axis, and B makes an angel of 45.0 below the negative x-axis. A=3.00 units and B=2
erik [133]
I think this is vectors. Sketch the two vectors A and B on the x axis and then find their magnitudes using cosine... i would like to know if i am correct.

When an oxygen atom forms an ion, it gains two electrons
kirill [66]
Note the atom of the Oxygen is electrically neutral, meaning it has equal numbers of electrons and protons.

So if it gains 2 electrons, it would have excess of 2 electrons, hence its charge would be -2.

Option B.

Which of the following is NOT a function of the lens in the eye?
tatyana61 [14]

Answer:

it is a light receptor that generates nerve signals that are sent to the brain

Explanation:

the lens are like the glasses, this means that is used to see things better. You just put them in your eye and that's all it's not connected to the brain
