<u>Properties of different planets</u>

Saturn is the second largest planet in the solar system and it’s most well-known for its bright and beautiful rings that circle its equator. These rings are composed of numerous ice and rock particles

Neptune has the strongest winds in the solar system and the winds are known for whipping the clouds at a speed of approximately 2000 Km/h

Astronomers used the orbit of Uranus to predict the existence of Neptune in 1846.

Jupiter has an iconic Great Red Spot just off the planet’s center which is approximately 1.3 times the Earth’s diameter and its winds move at a speed approximately 425 mph.

Answer:

Saturn: It is most well-known for its rings

Uranus: its orbit was used to predict the existence of another planet.

Neptune: It has the strongest winds in the solar system.

Jupiter: It has a giant storm three times the width of Earth.

Explanation:

Saturn: Saturn is most well-known for its rings and the ring system of Saturn can extend up to 282,000km or 175,000mile from the planet. The rings of Saturn together with the planet itself can fit in the distance between the Earth and the Moon.

Uranus: Uranus's orbit is used to predict the existence of another planet because It orbits the sun quite unusually, being the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees.

Neptune: Neptune has the strongest wind in the solar system as it is the fourth largest and the farthest planet of the Solar System with the most powerful wind speeds out of all the planets.

Jupiter: Jupiter is considered to be the fifth planet from the Sun and the largest planet of the Solar System. It is the oldest planet of the Solar System. Its size is twice the size of all other planet combined and it has a century old storm that is bigger than Earth.

Jason drives uphill from home to school, averaging 20 miles per hour. On the way back, he drives back downhill from school to ho

r-ruslan [8.4K]

Answer:

Average velocity = 30 miles per hour

Explanation:

Given that

Velocity for uphill = 20 miles per hour

Velocity for downhill = 60 miles per hour

We know that

Distance = Velocity x time

Total distance = Average velocity x total time

Lets take distance from home to school is s

Time taken from home to school= s/20 hr

Time taken from school to home= s/60 hr

Total time =s/20+s/60

Total distance = Average velocity x total time

s + s = Average velocity x (s/20+s/60)

So average velocity = 30 miles per hour

You're in a car that gets 28 miles per gallon of gas, driving it at a constant speed. If you took the gas from the car tank, and

Nataly [62]

Answer:

The diameter of the hose is 0.326 mm.

Explanation:

Given that,

Speed of car = 28 miles/galllon

We need to calculate the radius

The rate of flow of fluid is from the equation of continuity

$\dfrac{V}{t}=Av$

Where, A = area of cross sectional

$\dfrac{V}{t}=\pi r^2v$

We know that,

The velocity is the ratio of displacement of gas per unit time.

$\dfrac{V}{t}=\pi r^\dfrac{x}{t}$

$\dfrac{V}{x}=\pi r^2$

Put the value into the formula

$\dfrac{0.00378541}{28\times1609.34}=\pi r^2$

$r=\sqrt{\dfrac{0.00378541}{28\times1609.34\times\pi}}$

$r=1.63\times10^{-4}\ m$

We need to calculate the diameter of the hose

$d = 2r$

Put the value of r

$d=2\times1.63\times10^{-4}$

$d=0.326\ mm$

Hence, The diameter of the hose is 0.326 mm.

Ellie has two wire circuits, each connected to its own 6 V battery. One circuit has a resistance of 0.80 Ω. The other circuit ca

Vikentia [17]

The second circuit with 4.5 A current has more resistance.

Explanation:

potential difference= 6 V

resistance of first circuit=0.80 Ω

for second circuit, current= i=4.5 A

using Ohm's law V= i R

6=4.5 R

R=1.33 Ω

So the second circuit has a greater resistance.

g A raindrop charged to 10 mC experiences electric field of 10,000 V/m from a tip of a tree branch. What is the electric force a

Andrews [41]

Answer:

The electric force acting on the raindrop is 100 N.

Explanation:

Given;

charge of the raindrop, Q = 10 mC = 0.01 C

electric field strength, E = 10,000 V/m = 10,000 N/C

The force acting on the raindrop is given as;

Electric Force = electric field strength x charge of the raindrop

F = EQ

F = (10,000 N/C) (0.01 C)

F = 100 N

Therefore, the electric force acting on the raindrop is 100 N.

The cable supporting a 2130-kg elevator has a maximum strength of 2.18×104 n . what maximum upward acceleration can it give the

Vlada [557]

Answer;

=0.43 m/s²

Solution;

There will be the tension in the cable, T, upwards and the weight of the elevator, mg, downwards.

By Newton's second law, the sum of the forces will be equal to mass×acceleration.

Resultant force = m × a

Then T - mg = ma so the tension in the cable is

T = m(g+a)

The cable will break when T = 21,800 N

Solving for a, that happens when

a = 21800/2130 - g

= 10.23 - g (in m/s^2)

If you're using g = 9.8 m/s^2

Then the maximum acceleration allowed is 10.23-9.8 = 0.43 m/s^2
