Whats a relation between physics, biology and chemistry? normal answers only

Physics

ELEN [110]3 years ago

Comparison:

Physics: studies the behaviour of the universe, to keep it simple.

Chemistry: it's the study of matter and their properties/interactions.

Biology: studies life.

Conclusion

As you can see, all those subjects try to give us a deeper understanding of our surroundings. If we combine the study of matter, the study of the universe and the study of life we can reach unimaginable levels of knowledge.

Hope it helped,

Biology is the study of living thing,Physics is the study of matter and the law of nature to understand the behaviour of matter. Physics and Biology they learn about biological system in a molecular or atomic level

The base of a right prism is a rhombus with diagonals of 6 and 8. If the altitude of the prism is 12, what is the total surface
Agata [3.3K]

Answer:

total surface area is 432

Explanation:

Given data

base  = 6

diagonals = 8

altitude = 12

to find out

total surface area

solution

we know total surface area of prism is

total surface area = lateral surface area + 2base area  ..............1

so

first we calculate base perimeter i.e = 2 length + 2 width

so perimeter = 2(8) + 2(6) = 25

and area  = length * width = 8*6 = 48

so lateral surface area is perimeter * height i.e

lateral surface area = 28* 12

lateral surface area = 336

put this value in equation 1 we get

total surface area = lateral surface area + 2base area

total surface area = 336 + 2(48)

total surface area is 432

A law enforcement officer in an intergalactic "police car" turns on a red flashing light and sees it generate a flash every 1.2
butalik [34]

Answer:

The velocity of the police car relative to earth is v_{rel} = 2.51\times 10^{8} m/s

Given:

time for flash generation of the inter galactic police car, t = 1.2 s

time between flashes as measured from earth, t' = 2.2 s

Solution:

Utilising Einstein's equation for time dilation to calculate the velocity of the police car, the equation is given by:

t' = \frac{t}{\sqrt {1 - \frac{v^{2}}{c^{2}}}}                                (1)

where, c = speed of light in vacuum = c = 3\times 10^{8}

re arranging eqn (1) for velocity, v:

v_{rel} = c\times \sqrt {1 - (\frac{t}{t'})^{2}}                               (2)

Now, from eqn (2)

v_{rel} = 3\times 10^{8}( \sqrt {1 - (\frac{1.2}{2.2})^{2}})

v_{rel} = 3\times 10^{8}\times 0.838

v_{rel} = 2.51\times 10^{8} m/s

What are 2 way X-rays and radio waves are different
Kaylis [27]
There are two main points that should be emphasized about the different types of electromagnetic radiation. The sequence from longest wavelength (radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy

hope this helps you!✌

A horizontal spring with spring constant of 9.80 N/m is attached to a block with a mass of 1.20 kg that sits on a frictionless s
Andreas93 [3]

Answer:

Explanation:

Given

at certain point displacement and velocity is 0.345 m and 0.54 m/s

Therefore Potential and Kinetic Energy associated is

U=\frac{1}{2}kx^2

U=\frac{1}{2}\times 9.8\times (0.345)^2

U=0.583 J

Kinetic Energy K=\frac{1}{2}mv^2

k=\frac{1}{2}\times 1.2\times (0.54)^2=0.174 J

Total Energy T=U+K=0.583+0.174=0.757 J

Total Energy is conserved hence at maximum displacement  all energy will be Potential energy

T=\frac{1}{2}kA^2

where A=maximum displacement

0.757=\frac{1}{2}\times 9.8\times A^2

0.1544=A^2

A=0.393 m

Maximum speed occurs at equilibrium Position where Potential Energy is zero

thus T=\frac{1}{2}mv^2

0.757=\frac{1}{2}\times 1.2\times v_{max}^2

v_{max}=1.123 m/s

(c)When block is at 0.2 m from Equilibrium speed then its Potential Energy is

U=\frac{1}{2}kx^2=\frac{1}{2}\times 9.8\times (0.2)^2=0.196 J

T=U+K

K=0.757-0.196=0.561 J

K=\frac{1}{2}mv^2

0.561=\frac{1}{2}\times 1.2\times v^2

v=0.966 m/s
