The jovian planets contain a large percentage of the gases

Answers

Answer 1
Answer: The Jovian planets contain large percentage of Gases its because they are formed outside of what they called as frost line where temperature is low enough for ice condensation unlike terrestrial planets formed close to the sun where the temperature is very appropriate for metal and rock to condense.
Answer 2
Answer:

The Jovian planets contain a large percentage of the gases Hydrogen and Helium.

Animals in cold climates often depend on two layers of insulation: a layer of body fat [of thermal conductivity 0.200W/(m⋅K) ] surrounded by a layer of air trapped inside fur or down. We can model a black bear (Ursus americanus) as a sphere 1.60m in diameter having a layer of fat 3.90cm thick. (Actually, the thickness varies with the season, but we are interested in hibernation, when the fat layer is thickest.) In studies of bear hibernation, it was found that the outer surface layer of the fur is at 2.80∘C during hibernation, while the inner surface of the fat layer is at 30.9∘C a) What should the temperature at the fat-inner fur boundary be so that the bear loses heat at a rate of 51.4W ? b) How thick should the air layer (contained within the fur) be so that the bear loses heat at a rate of 51.4W ?

You lift a 45N bag of mulch? 1.2meters and carry it a distance of 10 meters how much work was done

Answers

W = Fxd
However, when you carry it, the actual bag of mulch isnt changing height so the only work done on the actual bag is when you lift it.
W = 45N x 1.2m
= 54J

If you notice that two waves combine and a part of the resulting wave has less light intensity than either of the individual waves, you're observing A. destructive interference. B. polarization. C. constructive interference. D. diffraction.

Answers

If you notice that two waves combine and a part of the resulting wave has less light intensity than either of the individual waves, you're observing destructive interference. Destructive interference happens when the two waves that combine have amplitudes with opposite signs,which results in subtraction- combined wave with a lower amplitude.

CONSIDER A TRAIN WHICH CAN ACCELERATION OF 20CM/SEC AND SLOW DOWN WITH ACCELERATION OF 100 CM/SEC FIND THE MINIMUM TIME FOR TRAIN TO TRAVEL BETWEEN THE STATIONS 2.7 KM PER A PART

Answers

The train accelerates at the rate of 20 for some time, until it's just exactly
time to put on the brakes, decelerate at the rate of 100, and come to a
screeching stop after a total distance of exactly 2.7 km.

The speed it reaches while accelerating is exactly the speed it starts decelerating from.

Speed reached while accelerating = (acceleration-1) (Time-1) = .2 time-1

Speed started from to slow down = (acceleration-2) (Time-2) = 1 time-2  

The speeds are equal.
.2 time-1 = 1 time-2
time-1 = 5 x time-2

It spends 5 times as long speeding up as it spends slowing down.

The distance it covers speeding up = 1/2 A (5T)-squared
= 0.1 x 25 T-squared = 2.5 T-squared.

The distance it covers slowing down = 1/2 A (T-squared)
= 0.5 T-squared.

Total distance = 2,700 meters.
(2.5 + .5) T-squared = 2,700
T-squared = 2700/3 = 900

T = 30 seconds

The train speeds up for 150 seconds, reaching a speed of 30 meters per sec
and covering 2,250 meters. 
It then slows down for 30 seconds, covering 450 meters.

Total time = 180 sec = 3 minutes, minimum.

Observation:
This solution is worth more than 5 points.
This can be done by hit and trial easily.

Considering train accelerate for 13000s and deaccelerate for 1000s
so total distance covered is = 20cm/s * 13000s + 100cm/s*100s
= (260000 + 10000 )cm
= 270000cm
= 2.7km

So total time taken is - 13100 seconds

Describe a ways car manufacturers try to reduce drag and why.

Answers

Aerodynamic drag can be reduced by altering the density of the air and the vehicle speed, but these factors are not easily controlled. Instead, to reduce drag, car manufacturers can make the height and width of the front of the car smaller. ... This shape reduces drag and the forces that try to propel the car backwards

Aerodynamics is a way to reduce drag that uses car manufacturers.

What is aerodynamic ?

Aerodynamics is the motion of the air. airplane flies cause of aerodynamics.

Aerodynamics is the study of forces that are resulted by motion of the air.

To reduce the aerodynamic drag further, the manufacturers use character lines on the exteriors of the car's body right from its concept stage. These lines help the air to pass smoothly over the body and thus, reducing the air resistance.

cars have flat vertical face in front. When it moves through air, drag force directly proportional to the velocity applies on the car which opposes motion of the car. after studding aerodynamics when we make triangular like shape to the front body of the car, it cuts the air and front air goes from side of the car which reduces oppose to the motion, and car can have more speed.

An 8.10 kilogram box of mass is kept at a height of 0.99 meters above ground level. What is the potential energy of the box? (given g = 9.8 meters/second2). A. 68 joules. B. 79 joules. C. 81 joules. D. 99 joules. E. 1.0 × 102 joules

Answers

The answer is B. 79 joules.

To calculate this we will use the formula for potential energy (PE):
PE = m * g * h
where m is mass of an object, g is gravitational acceleration, h is a height at which is the object.

It s given:
m = 8.10 kg
g = 9.8 m/s²
h = 0.99 m

After replacing them in the formula for potential energy:
PE = 8.10 * 9.8 * 0.99 = 78.6 J ≈ 79 J

The answer would be 79J because when you multiply 8.1*0.99*9.8 you get 7.89, which rounds to 7.9.

Answer choice (B).
