Different theories in science rely on the current available knowledge that has been obtained through a certain way of data collection/that has used certain technology to obtain such data. With new technology, new datasets can be obtained that perhaps are not in line with previous theories. By improving technology, new datasets can be obtained and through this theories can be advanced, improved and developed.

ou are walking down a straight path in a park and notice there is another person walking some distance ahead of you. The distanc

alexgriva [62]

Answer:

The value is $d = 31.45 \ m$

Explanation:

Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as

$v_r = v_s - v_c$

substituting 1.05 m/s for $v_c$ and 2.75 m/s for $v_s$

So

$v_r = 2.75 - 1.05$

=> $v_r = 1.7 \ m/s$

Generally the distance by which the person is ahead of you is mathematically represented as

$d = v_r * t$

substituting 18.5 s for $t$

$d = 1.7 * 18.5$

=> $d = 31.45 \ m$

A two-dimensional crystal has a rectangular unit cell, with spacings between the centers of the atoms of 0.5 nm in one direction

pav-90 [236]

So directly the cell density value in a rectangle is:

$5*10^{17} cells/cm^{2}$

In this exercise, we must first calculate the area of the rectangle, remembering that you need to convert from nm to cm is:

$A=B*H\\A=(0.4*10^{-7})*(0.5*10^{-7})= 2*10^{-15}$

Next, let's calculate the density from the calculated area:

$\frac{N}{A} = \frac{1000}{2*10^{-15} } = 5*10^{17}$

In this way, the calculation represents that there is:

$5*10^{17} cells/cm^{2}$

Absolute zero (K=0 or -273.15°C) is what temperature on the Farenheit scale? a) 459.4°F b) -301.43 °F c) 233.05°F d) -40.15°F e

ANEK [815]

Answer:

e) None of these is true

Explanation:

Given that

Temperature = 0 K

We know that relationship between kelvin and Farenheit scale

$\dfrac{K-273}{100}=\dfrac{F-32}{180}$

Now by putting the values

$\dfrac{K-273}{100}=\dfrac{F-32}{180}$

$\dfrac{0-273}{100}=\dfrac{F-32}{180}$

So F= - 459.67°F

So we can say that 0 K is equal to - 459.67°F.

So the our option e is correct.
