1) which planet's orbit was Kepler first studying when he began to developed his laws of orbital motion? Answer: Mars

2) which is the best description of Earth's orbit? Answer: almost circular

3) which orbital shape did most scientists in the early 1600s think the planets of our solar system have? Answer: circular

4) which of these describes Kepler's third law of orbital motion? Answer T^2 OX a^3

5) which statement describes Kepler's third law of orbital motion? Answer The square of orbital period is proportional to the cube of the semi-major axis.

Explanation:

I just took the connexus quick check and got a 100%

T2 ∝ a3 is the relation that describes Kepler’s third law of orbital motion, therefore the correct answer is option C.

There are three laws of Kepler as follows,

The orbit of the planet is elliptical and the sun is present at one of the two foci of the elliptical route followed by the rotating planet.

A line segment linking a planet and the Sun covers equal regions throughout equal intervals of the time period.

The semi-major axis length of an elliptical planet's orbit is equal to the square of the planet's orbital period.

T2 ∝ a3 is the relation that describes Kepler’s third law of orbital motion,

Thus, the correct answer is option C.

Answer:

The key difference between ionic bonding and metallic bonding is that the ionic bonding takes place between positive and negative ions whereas the metallic bonding takes place between positive ions and electrons.

Explanation:

About (metallic bonding) → Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons and positively charged metal ions.

About (ionic bonding) → Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds

The main difference between potential and kinetic energy is that one is the energy of what can be and one is the energy of what is. In other words, potential energy is stationary, with stored energy to be released; kinetic energy is energy in motion, actively using energy for movement.

Answer:

The weight of an object is the force it exerts due to gravity. Pressure is force per unit area, or force divided by area over which the pressure is exerted.

Answer:

What did this scientist discover?

Nikola Tesla discovered and created Bluetooth back in 19, November 5, 1898.

"The Transmission of Electrical Energy Without Wires", Electrical World and Engineer, January 7, 1905. Tesla, Nikola, World System of Wireless Transmission of Energy, Telegraph and Telegraph Age, October 16, 1927.

How was it discovered?

In 1901 Tesla began his work of a large high-voltage wireless energy transmission station called the Wardenclyffe Tower. ... Some devices already employ wireless energy transfer without the use of metal contacts. The power is transferred through the plastic cases using magnetic induction.

How does this discovery or invention impact the world today?

It changed the new age by listening to music with wireless earbuds.

Answer:

Explanation:

N = mg = (1.00 + 0.500)(9.81) = 14.7 N

The magnitude of the normal force exerted on book A by the table is 14.7 N

From the question, we are to determine the magnitude of the normal force.

The normal force ca be calculated by using the formula

[tex]F_{n} = mg[/tex]

Where [tex]F_{n}[/tex] is the normal force

m is the mass

and g is the gravitational field strength ( g = 9.8 m/s²)

The mass will be addition of the masses since Book B is placed on top of the book.

Thus,

m = 1.00 kg + 0.500 kg = 1.50 kg

Then,

[tex]F_{n} = 1.5 \times 9.8[/tex]

[tex]F_{n} = 14.7 \ N[/tex]

Hence, the magnitude of the normal force exerted on book A by the table is 14.7 N

The displacement of your motion during the entire motion is 22.5 m

The given parameters;

The displacement of your motion during the entire motion is calculated from your average velocity and time of motion.

This magnitude of this displacement is calculated  as follows;

[tex]s = (\frac{u+ v}{2} )t\\\\s = (\frac{1.5 + 3}{2} ) \times 10\\\\s = 22.5 \ m[/tex]

Thus, the displacement of your motion during the entire motion is 22.5 m.

Answer:

Explanation:

The resistor R2 is shorted out, so is not in the circuit. The remaining resistors are in a series circuit with a total resistance of ...

  R1 +R3 +R4 = 1k +4.7k +1k = 6.7k

The current is the ratio of the applied voltage to this total resistance:

  I = V/R = (9 v)/(6.7k) ≈ 1.3433 mA

The voltage across each resistor is the product of this current value and the resistance:

  R1 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts

  R2 voltage = 0

  R3 voltage = (4.7 kΩ)(1.3433 mA) = 6.3134 volts

  R4 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts

Option D is correct. Around the age of five, children begin to experience their first dreams and nightmares

By the time children are five years old, several developments occur in their sleep patterns.

Option A is incorrect because the typical 90-minute sleep cycles of alternating REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement) are not yet established at this age.

Option B is also incorrect as the sleep time distribution between REM sleep and quiet sleep (similar to NREM stages 1 and 2) is not necessarily equal at this stage.

Option C is inaccurate because 60-minute sleep cycles producing up to 13 cycles per day do not align with the typical sleep patterns of five-year-olds.

However, option D is correct. Around the age of five, children begin to experience their first dreams and nightmares.

This is an important milestone in their cognitive and emotional development, as it reflects the maturation of the brain regions involved in dreaming and the processing of emotions during sleep.

Answer:

Explanation:

The lift force will have a vertical component equal to the weight of the plane and a horizontal component sufficient to supply the needed centripetal accleration.

R = 8.01 mi = 12891 m

ω = 2π/T =  2π/(0.106(3600)) = 0.016465 rad/s

F = m√(g² + (ω²R)²)

F = 8930√(9.81² + (0.016465²(12891))²)

F = 8930√(9.81² + 3.49²)

F = 92,996.480...

F = 93.0 kN

θ = arctan(3.49/9.81) = 19.6°
