Did the heliocentric model explain the drawbacks of the geocentric model?

Answers

Answer 1

Answer:

uuuugggghhhhhhhhggggffffffffffffff

Answer 2

Answer:

The geocentric model could not fully explain these changes in the appearance of the inferior planets (the planets between the Earth and the Sun). Furthermore, Galileo's observations of Jupiter's moons made it clear that celestial bodies do move about centers other than the Earth.

You have given us a very weird question. Things do not mesh

If the mass is 500 kg and sits 25 m above the lowest spot on the track, the potential energy is

PE  = mgh = 500(9.8)(25) = 122500 Joules,

not the reported 61250 Joules

So either the Joules is incorrect or the mass is supposed to be 250 kg.

In either case, in the absence of friction, the potential energy will convert to kinetic energy.

½mv² = mgh

     v = √2gh

which does not involve the use of either Joules or kilograms.

Maximum velocity when starting from rest is

v = √(2(9.8)25) = √490 = 22.135943...

v = 22 m/s

Weight of 1kg, 1.5kg and 2kg are attached at distance of 1m 5m and 7m respectively from the same end.
find the tension in each vertical string

Answers

Answer:

Fp = 36 N

Fq = 58 N

Explanation:

Let the left end be the reference end with string p closest to it.

Let CCW moments be positive

Sum moments about p to zero

1(9.8)[2 - 1] + Fq[6 - 2] - 5(9.8)[8/2 - 2] - 1.5(9.8)[5 - 2] - 2(9.8)[7 - 2] = 0

                                                                              Fq[4] = 23.5(9.8)

                                                                                  Fq = 57.575 ≈ 58 N

Sum moments about q to zero

1(9.8)[6 - 1]  - Fp[6 - 2] + 5(9.8)[6 - 8/2] + 1.5(9.8)[6 - 5] - 2(9.8)[7 - 6] = 0

                                                                                                     Fp = 35.525 N

or

Sum vertical forces to zero

Fp + 57.575 - (9.8)(1 + 1.5 + 2 + 5) = 0

Fp = 35.525  ≈ 36 N

If a ball is kicked horizontally off of a building at 8.0 m/s, what is the horizontal velocity (vx) after 3
seconds?

Answers

The characteristics of the projectile launch allows to find the result for the velocity on the x axis is:

In the horizontal axis there is no acceleration and therefore the speed must be kept constant. The horizontal speed is  vₓ = 8.0 m / s

In projectile launching we have an application of kinematics to motion in two dimensions near the surface of the Earth.

In this case, on the vertical axis we have an acceleration directed towards the center of the planet and called the gravity acceleration.

In the horizontal axis or x axis there is not acceleration, except in special cases that we tone is how much the resistance of the air.

Consequently in the horizontal axis there is no acceleration and therefore the speed must be kept constant, the result for the horizontal speed is:

           vₓ = 8.0 m / s

A.They both hit the ground at the same time

B.Which hits first depends on the weather & temperature of the air.

C.The 200 g gold coin hits the ground first

D.The 10 g dime hits the ground first

Answers

Answer:

Explanation:

The both hit the ground at the same time. There is no air resistance and that includes the factors brought up in B.

C and D are both eliminated. If you dropped an 800 kg honda Fit it would hit the ground at the same time as the two coins. When you look at the formulas used to derive time, they look like

d = vi * t + 1/2 a* t^2

vi = 0

the distance to fell is the same for all three masses.

a is the same for all 3 masses.

So when you solve for t, there is no mention of the mass of the object falling. Therefore t is dependent only on the height.

A snowboarder drops from rest into a halfpipe of radius R and slides down its frictionless surface to the bottom

(a) Show that the snowboarder's speed at the bottom of the halfpipe is
v = 2gR (use conservation of energy)
(b) Show that the snowboarder's centripetal acceleration at the bottom is
ac = 2g (Apply the expression for centripetal acceleration)
(c) Show that the normal force on the snowboarder at the bottom of the halfpipe has a magnitude of 3mg (Use Newton's second law of motion)

Answers

A snowboarder drops from rest into a halfpipe of radius R and slides down its frictionless surface to the bottom, the snowboarder's speed is [tex]\mathbf{v = \sqrt{2gR}}[/tex]

The snowboarder's centripetal acceleration at the bottom is [tex]\mathbf{a_c = 2g}[/tex]. The normal force acting on the snowboarder at the bottom of the halfpipe = 3mg

According to the conservation of energy, at any given point of motion, the energy of a system will always be constant.

Using the conservation of energy at rest and also at the bottom of the pipe.

Total potential energy of the person(since its at rest = Total kinetic energy at the bottom of the pipe.

[tex]\mathbf{mgR = \dfrac{1}{2}mv^2}[/tex]

The objective is to make the velocity (v) the subject of the formula:

[tex]\mathbf{gR = \dfrac{1}{2}v^2}[/tex]

[tex]\mathbf{2gR = v^2}[/tex]

[tex]\mathbf{v = \sqrt{2gR}}[/tex]

(b)

Using the expression for centripetal acceleration;

[tex]\mathbf{a_c = \dfrac{v^2}{R}}[/tex]

here,

let's replace [tex]\mathbf{v \ \ \ with \ \ \sqrt{2gR}}[/tex];

Then;

[tex]\mathbf{a_c = \dfrac{(\sqrt{2gR})^2}{R}}[/tex]

[tex]\mathbf{a_c =2g}[/tex]

From the image attached below;

Provided that:

n = normal forcew = mg  weight of the person[tex]\mathbf{F_c}[/tex] = centripetal force

Then, we can infer that the normal net force acting on the person can be computed as:

[tex]\mathbf{F_c = n -mg}[/tex]

By rearrangement;

[tex]\mathbf{n =F_c +mg}[/tex]

where;

[tex]\mathbf{F_c = 2 mg}[/tex]

n = 2mg + mg

n = 3mg

Therefore, we can conclude that the snowboarder's speed, centripetal force, and normal force are proved.

A 20 N force pulls to the right and friction pulls 5 N. If the mass is 5 kg, find acceleration.​

Answers

Answer:

Explanation:

Force - frictional Force = m * a

20N - 5N = 5 * a

15N = 5*a

15N / 5 = a

a = 3 m/s^2

You should note a couple of things.

1. The frictional Force always opposes the direction of motion. In this case it is minus and the 20 N is plus. It makes the acceleration less. If the friction force was not there then 20 N = m * a

20N = 5 kg * a

a = 20/5

a = 4 m/s^2.
