Why society might initially reject a new scientific theory?

1 answer:

6 0

I was about to say: because people generally get comfortable with
what they think they know, and don't like the discomfort of being told
that they have to change something they're comfortable with.

But then I thought about it a little bit more, and I have a different answer.

"Society" might initially reject a new scientific theory, because 'society'
is totally unequipped to render judgement of any kind regarding any
development in Science.

First of all, 'Society' is a thing that's made of a bunch of people, so it's
inherently unequipped to deal with scientific news. Anything that 'Society'
decides has a lot of the mob psychology in it, and a public opinion poll or
a popularity contest are terrible ways to evaluate a scientific discovery.

Second, let's face it. The main ingredient that comprises 'Society' ... people ...
are generally uneducated, unknowledgeable, unqualified, and clueless in the
substance, the history, and the methods of scientific inquiry and reporting.

There may be very good reasons that some particular a new scientific theory
should be rejected, or at least seriously questioned. But believe me, 'Society'
doesn't have them.

That's pretty much why.

It is difficult to extinguish a fire on a crude oil tanker, because each liter of crude oil releases 2.80 × 10 7 J of energy whe

Answer:

10.4L of water is expended when 1L of crude oil is burned.

Explanation:

This problem requires us to calculate the volume of water that must be expended to absorb the amount of energy released from the burning of 1.00L of crude oil.

In going from water at 18.5°C to steam at 285°C, the water undergoes 3 stages:

Absorption of heat from 18.5°C to 100°C >> phase change to vapour at 100°C >> heating from 100°C to steam at 285°C

Given Cw = 4186 J/kg°C and Cs = 2020 J/kg°C. The latent heat of of vaporization of water Lv = 2.256 ×10⁶ J/kg

The total heat absorbed in the process per kilogram

H = Cw × (100 – 18.5) + Lv + Cs × (285 – 100)

H = 4186 × 81.5 + 2. 256 ×10⁶ + 2020× 185

= 2.696 ×10⁶ J/kg

The amount of heat in J/L of water needed can be calculated as follows:

Density of water = 1000kg/m³ =

1000 kg/m³ × 1m³/1000L = 1kg/L (Basically conversion of density in kg/m³ to kg/L)

Let the volume of water needed be V litres.

Then the mass of water that must be expended = Density × Volume

= 1kg/L × V L = Vkg

The heat that would be absorbed by the water when 1L of crude oil is burned is V×H

= 2.696×10⁶ × V

This is also equal to 2.80×10⁷ J of energy (given).

So,

2.696×10⁶V = 2.8×10⁷

V = (2.80×10⁷)/(2.696×10⁶) = 10.4L of water.

How far will it go, given that the coefficient of kinetic friction is 0.10 and the push imparts an initial speed of 3.9 m/s ?

Akimi4 [234]

Answer:19.5 m

Explanation:

Given

coefficient of kinetic Friction $\mu _k=0.10$

Initial speed $u=3.9\ m/s$

Friction is present so it tries to stop to the object and stops it completely after moving certain distance let say s

maximum deceleration provided by friction is

$a_{max}=\mu _k\cdot g$

$a_{max}=0.1\times 3.9=0.39\ m/s^2$

using equation of motion

$v^2-u^2=2 as$

where $v=final\ velocity$

$u=initial velocity$

$a=acceleration$

$s=displacement$

$(0)-(3.9)^2=2\times (-0.39)\times s$

$s=19.5\ m$

Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of length 1.25 m and finds that it makes 419

Zina [86]

Answer:

$g=2406.8m/s^{2}$

Explanation:

firstly we have to find the frequency and then the angular frequency.

The frequency will be:

$f=\frac{419}{60} \\f=6.98Hz$

The angular frequency is:

ω $=2\pi f$

ω $=2*\frac{22}{7} *6.98$

ω $=43.88rad /sec$

Now we can apply simple pendulum relationship

ω $=\sqrt{\frac{g}{l} }$

make g the subject of the formula

$g=w^{2} l\\g=43.88^{2} *1.25\\g=2406.8m/s^{2}$

A squirrel, a train, a bird, and a car are all traveling at the same velocity. Which object has the greatest amount of kinetic e

Tanzania [10]

The greatest amount of kinetic energy is found with the train because it takes most energy to reach that velocity and also to slow down to a halt.
