The gravitational effect on other bodies determines the weight (or the mass) of a planet. We must somehow measure the strength of its "tug" on another object in order to use gravity to find the mass of a planet. We can harness Newton's equations to deduce what the mass of the planet must be through observing the time it takes for the satellite to orbit its primary planet.

 

Given:

 

Mass of Venus = 4.87 x 1024 kg

= 4986.88

Mass of Jupiter = 1.898 x 1024 kg

= 1943.552

Mass of Jupiter compared to mass of Venus

 

1943.552 / 4986.88

= 0.3897330595482546

= 0.3897330595482546 x 100%

= 38.97%

 

So, in this problem, <span>the mass of Jupiter is about 0.39 times the mass of Venus.</span>

8. A car initially has 100 J of total energy. After driving down the road, the car's
sveta [45]

The work done on the car is -20 J.

Work done on the car is negative, meaning that the car actually does work on the external system.

<h3>Energy and law of conservation of energy</h3>
  • Energy is the ability to do work
  • the law of conservation of energy states that the total energy in a system is conserved

From the law of conservation of energy, the initial energy of the car before it moves down the road remains constant or unchanged.

  • Initial energy = 100 J
  • Initial energy = Final energy - work done on car
  • Final Energy = Work done on car + initial energy

80J = Work done on car + 100 J

Work done on car = 80 - 100J

Work done on car = -20 J

Hence, the work done on the car is -20 J

Work done on car is negative.

Since work done on the car is negative, it means that the car actually does work on the external system. Hence, the decrease in the energy of the car.

To provide some perspective on the dimensions of atomic defects, consider a metal specimen that has a dislocation density of 105
-Dominant- [34]

Explanation:

LD₁ = 10⁵ mm⁻²

LD₂ = 10⁴mm⁻²

V = 1000 mm³

Distance = (LD)(V)

Distance₁ = (10⁵mm⁻²)(1000mm³) = 10×10⁷mm = 10×10⁴m

Distance₂ = (10⁹mm⁻²)(1000mm³) = 1×10¹² mm = 1×10⁹ m

Conversion to miles:

Distance₁ = 10×10⁴ m / 1609m = 62 miles

Distance₂ = 10×10⁹m / 1609 m = 621,504 miles.

The bear is white in color because it is a polar bear.

<h3>What are the color of bears?</h3>

Bears are very large carnivorous animals found around the cold regions of the Arctic or North Pole.

The color of bears, may be brown, black or white depending on how far North the bears are found.

Bears found close to the Arctic or North pole are white polar bears.

Based on the description of the house, every side of the home faces South meaning that the individual lives in the North pole.

Therefore, the color of the bear will be white.

in conclusion, polar bears are white in color.
