Give me an example of a case where the branches of natural science appear to overlap

1 answer:

4 0

There are numerous example wherein the branches of natural science appear to overlap. The fields include, biophysics, biochemistry, biopsychology, neurophysics, geochemistry, and etc. these sciences that are clustered majorly as chemistry, physics, biology, geology and other major sciences are aggregated into a subbranch that are now cross-sciences because with the help of one spectrum or field it can also support and explain other certain phenomemons like why do living creatures eat (Biology) and what do they eat what are then the molecular compositions or atomical compositions of these goods (Chemistry), and in plants why does some plants bend and how much in order to attain sunlight (Physics and biology) and lastly, what type of soil do most plants or creatures adapt to (Geology).

A certain CD has a playing time of 74.0 minutes. When the music starts, the CD is rotating at an angular speed of 480 revolution

Rashid [163]

Answer: $0.00636\ rad/s^2$

Explanation:

Given

CD has a playing time of $t=74\ min\ or\ 74\times 60\ s$

Initial angular speed of CD is $480\ rpm$

Final angular speed of DC is $210\ rpm$

Angular speed, when rpm is given

$\omega =\dfrac{2\pi N}{60}$

$\omega_i=\dfrac{2\pi \times 480}{60}\\\\\Rightarrow \omega_i=16\pi \ rad/s$

Final speed

$\Rightarrow \omega_f=\dfrac{2\pi \times 210}{60}\\\\\Rightarrow \omega_f=7\pi \ rad/s$

Using equation of angular motion

$\Rightarrow \omega_f=\omega_i+\alpha t$

Insert the values

$\Rightarrow 7\pi =16\pi +\alpha \times 74\times 60\\\Rightarrow -9\pi =\alpha \cdot (4440)\\\\\Rightarrow \alpha=-\dfrac{9\pi}{4440}\\\\\Rightarrow \alpha=-0.00636\ rad/s^2$

Magnitude of angular acceleration is $0.00636\ rad/s^2$

An object has 90000 J of kinetic energy and is moving at 12 m/s. what is the objects mass?

Klio2033 [76]

Answer:

1250kg

Explanation:

we can solve this using the formula for the Kinetic Energy

$Kinetic.Energy=\frac{1}{2}*mass*velocity^{2}\\mass=\frac{2*Kinetic.Energy}{velocity^{2}}\\mass=\frac{2*90000}{12^{2}}\\\\mass=1250kg$

Challenge: Determine the speed of the waves at each tension setting (high, medium and low). Explain what measurements you made t

Svetradugi [14.3K]

Answer:

high tension: 4.2 × 1.5 = 6.3 cm/s

medium tension: 2.8 ×1.5 = 4.2 cm/s

low tension: 0.8 × 1.5 = 1.2 cm/s

Explanation: Given Settings:

amplitude: 0.75 cm

damping: zero

Using

Speed = frequency ×wavelength

Where

Wavelength = 0.75 × 2 = 1.5 cm

Therefore:

high tension: 4.2 × 1.5 = 6.3 cm/s

medium tension: 2.8 ×1.5 = 4.2 cm/s

low tension: 0.8 × 1.5 = 1.2 cm/s
