How has the model of our solar system changed over time?

Answers

It depends.Ptolemy was one of the most famous astronomers who was convinced that or solar system was geocentric, or revolving around the earth. Then, Copernicus came around, along with Galileo, and the attempted to convince people that that wasn't true, but that we were revolving around the sun. In fact, if you're writing an essay, a good point to add would be that Galileo spent a large part of his life imprisoned for "disobedience of the (Roman) Gods.)"

It always depends of how our solar system changed over time.

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).

What is the difference between magnetic field and magnetic flux

Answers

Explanation:

The region around a moving charge in which it experience a force is called magnetic field. The force is called magnetic force. The force experienced due to moving charge is given by :

$F=q(v* B)$

q is the charged particle

v is the speed of particle

B is the magnetic field

The number of magnetic field lines passing through any surface is called magnetic flux. The formula used to find the magnetic flux is given by :

$\phi=B.A$

$\phi=BA\ cos\theta$

Hence, this is the required solution.

consider the phrase, " the quick brown fox jumped over the lazy dog." which details of this situation would a physicist who is modeling the path of a fox ignore?

Answers

The physicistmodelling the path of the fox will ignore the colour of the fox and the strength of both animals.

The given phrase:

"the quick brown fox jumped over the lazy dog."

To find:

the detail of the of the given statement which will be ignored by a physicist modelling the path of the fox.

The path of a motion is determined by:

time of motion

direction of motion

speed of motion,
the motion's trajectory, etc

The physicist will ignore the following details in the givenphrase:

the colour (brown)of the for: this is irrelevant to the motion of the fox
the strength(lazy) of both fox and dog

Thus, the physicist modelling the path of the fox will ignore the colour of the fox and the strength of both animals.

Answer:

Air resistance.

Explanation:

In this scenario the fox is jumped over the lazy dog then the trajectory of the fox will be parabolic. The physicist solve this problem by the help of projectile motion by taking vertical and horizontal component to solve this by using newton equation of motion.

But he should neglect or ignore the air resistance because the addition of air resistance will make the path more difficult and the problem will become tougher to apply newton equation to find the value up to more precision.

What is latent heat of fusion ...

Answers

The latent heat required for a solid to melt into liquid is called the Latent of Fusion.
This latent heat does not increase the kinetic energy of the substance undergoing a state change and thus doesn't show its presence by increasing temperature.

The enthalpy of fusion also known as (latent) heat of fusion is the change in enthalpy resulting from heating a given quantity of a substance to change its state from a solid to a liquid. The temperature at which this occurs is the melting point.

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 ?
