If two planets are close enough to each other do they have a greater gravitational pull then two planets that are farther away?

(ex: let's say the planets are about the same size!)

Yes because if they are further away it makes it hard for them to attract each other

Answer: I would say Yes because they further away they are from each other the harder it is for the plants to interact with each other. the further away they are the harder it is for them. Hopefully this helps!!

Write a scientific question that is specific and testable. Jack and Jill when up a hill to fetch a pail of water. Once they got
Naya [18.7K]

The scientific method consists of making an observation, ask a question, formulate hypothesis, predict, test, iterate

The scientific question that can be asked is; <u>What is the </u><u>depth of the well</u>

<u />

The reason why the above question is appropriate is as follows:

The items Jack and Jill found at the well

  • No pail
  • A stopwatch
  • Nine equal sized rocks

The information they can get using what they found are;

The time it takes the rock to reach the water surface in the well

The depth of the well

The well's depth, <em>h</em>, is given using the equation of free fall, as follows;

h = \dfrac{1}{2} \cdot g \cdot t^2

Where;

g ≈ Acceleration due to gravity ≈ 9.81 m/s²

By recording the time each rock takes to reach the water surface in the well, the average depth of the well, h_{ave}, can be found by finding the average of the 9 calculated values for <em>h</em> using the 9 stones

Therefore;

The scientific question that is specific and testable is <u>how </u><u>deep </u><u>is the </u><u>well</u><u>, or what is the well's depth</u>

A thin uniform rod (mass = 0.53 kg) swings about an axis that passes through one end of the rod and is perpendicular to the plan
gladu [14]

Answer:

(a) L = 0·73 m

(b) 4·39 × 10^{-3} J

Explanation:

(a) From the figure, consider the torque about the point where the rod is attached because if we consider another point then there will be hinge forces acting on the rod at the point of attachment

Let L m be the length of the rod and β be the angle between the rod and the vertical

Let α be the angular acceleration of the rod

As the force of gravity acts at the centre so from the figure, the torque about the point of attachment will be 0·53 × g ×(L ÷ 2) ×sinβ

Assuming that the value of amplitude of this oscillation to be small

As torque = moment of inertia × angular acceleration

0·53 × g ×(L ÷ 2) ×sinβ = ((0·53 × L²) ÷ 3) × α (∵ moment of inertia of the rod from the point of attachment)

<h3>For small oscillations, α = ω² × β</h3>

After substituting the value of α and solving we get

ω = √((3 × g) ÷ (2 × L))

Time period = (2 × π) ÷ ω =  (2 × π) ÷ √((3 × g) ÷ (2 × L))

∴ (2 × π) ÷ √((3 × g) ÷ (2 × L)) = 1·4

Substituting the value of g as 9·8 m/s² and solving we get

L = 0·73 m

(b) At the maximum amplitude condition the velocity will be 0 and potential energy will be maximum and maximum kinetic energy will be attained at the lowest point and hinge forces will not do work as the point of attachment is not moving

∴ Taking the reference for finding the potential energy as the lowest point

<h3>Maximum potential energy = Maximum kinetic energy </h3><h3>As total energy is constant, since there is no dissipative force</h3>

Maximum potential energy =  (0·53 × g × L ×(1 - cosβ)) ÷ 2 (∵ increment in height is (L × (1 - cosβ)) ÷ 2

∴ Maximum potential energy =  (0·53 × g × L ×(1 - cosβ)) ÷ 2 After substituting the value we get

Maximum potential energy = 4·39 × 10^{-3} J

∴ Maximum kinetic energy = 4·39 × 10^{-3} J

What are the similarities between strong nuclear force and weak nuclear force
Artemon [7]
Alike because they both act on the quarks making up the nucleons and they have very short ranges. The Strong Nuclear Force is an attractive force between protons and neutrons that keep the nucleus together and the Weak Nuclear Force is responsible for the radioactive decay of certain nuclei. Which also makes them very different

A ball is dropped from an aircraft flying at an altitude of 8,848 meters assuming gravity is 9.8m/s what is the total amount of
Dafna11 [192]
In this question, you're determining the time (t) taken for an object to fall from a distance (d).

The equation to represent this is:
Time equals the square root of 2 times the distance divided by the gravitational force of earth.
In equation from it looks like this (there isn't an icon to represent square root so just pretend like there's a square root there):
t = 2d/g (square-rooted)

d = 8,848m and g = 9.8m/s

Now plug in the information we have:
t = 2 x 8,848m/9.8m/s (square-rooted)

The first step is to multiply 2 times 8,848m:
t = 17,696m/9.8m/s (square-rooted)

Now divide 9.8m/s by 17,696m (note that the two m's (meters) cancels out leaving you with only s (seconds):
t = 1805.72s (square-rooted)

Now for the last step, find the square root of the remaining number:
t = 42.5s

So the time it takes the ball to drop from the height (distance) of 8,848 meters, and falling with the gravitational pull of 9.8 meters per second is 42.5 seconds.

I hope this helps :)

What is Brewster's angle for an air-glass n = 1.58 surface
arlik [135]

n₂ = index of refraction of glass = 1.58

n₁ = index of refraction of air = 1

θ = Brewster's angle

Brewster's angle is that incident angle at which the the reflected light from the interface of two medium is completely polarized.

Brewster's angle is given as

θ = tan⁻¹(n₂ /n₁ )

θ = tan⁻¹(1.58/1 )

θ = 57.7 deg

hence the Brewster's angle comes out to be 57.7 deg
