Why is physics an important part of history

Physics
2 answers:
tigry1 [53]4 years ago
8 0

Answer:

History and physics are intertwined through all the revolutionary thinkers, scientists, and people who studied these ideas. For example, many historical thinkers such as Isaac Newton and Galileo Galilei not only had revolutionary ideas, but they also changed life forever as the people knew it. It shocked the people and taught them new things, and upset the church.

History is often disregarded in the study of physics, yet it is inherently connected to scientific inquiry through documentation of theory and subject matter through time. Scientific figures throughout history often serve as role models and examples for future physicists as well. Dredging up the history textbooks may seem like an absurd way to advance science, but consider: History involves ideas, theories, and equations that become the foundation for future improvements. Here are six reasons why understanding the history of physics could be useful to physicists and future physicists alike.

What does it mean if the moon is waxing and waning
konstantin123 [22]
Both verbs come from Olde English. 
That's why everybody clearly understood their meaning until
a hundred years ago, but nobody understands them now.


"Waxing"  =  growing

For two weeks after the New Moon, it's growing toward Full.
First it's a waxing crescent for a week, then it's waxing gibbous.


"Waning"  =  shrinking

For two weeks after the Full Moon, it's shrinking toward New.
First it's waning gibbous for a week, then it's a waning crescent.

What disadvantage of convex mirror​
Eddi Din [679]

Answer:

The disadvantage is that convex mirror is that they make it appear like those objects are at a more noteworthy distance than they actually are. It always gives a virtual, erect and a diminished image.

A ship's propeller of diameter 3 m makes 10.6 revolutions in 30s. What is the angular velocity of the propeller?
ycow [4]

Answer:

The angular velocity of the propeller is 2.22 rad/s.

Explanation:

The angular velocity (ω) of the propeller is:  

\omega = \frac{\Delta \theta}{\Delta t}                              

Where:

θ: is the angular displacement = 10.6 revolutions

t: is the time = 30 s

\omega = \frac{\Delta \theta}{\Delta t} = \frac{10.6 rev*\frac{2\pi rad}{1 rev}}{30 s} = 2.22 rad/s

Therefore, the angular velocity of the propeller is 2.22 rad/s.

I hope it helps you!

three resistors which values of 15 ohm 40 ohm 60 ohm respectively are connected in parallel. what is their equivalent resistance
VashaNatasha [74]

1) Equivalent resistance, 1/R = 1/15 + 1/40 + 1/60 = 8+3+2 /120 = 13/120

R = 120/13 = 9.23

2) Current, I = V/R = 115/9.23 = 12.45 A

A particle has a charge of +1.5 µC and moves from point A to point B, a distance of 0.15 m. The particle experiences a constant
kirill [66]

Answer:

Part a)

F = 6 \times 10^{-3} N

Direction of force is along the motion of charge

Part b)

E = 4000 N/C

direction of electric field is along the direction of motion

Explanation:

Part a)

As we know that the change in electric potential energy is equal to the work done by electric field

W = EPE_A - EPE_B

W = 9.0 \times 10^{-4} J

now from the equation of work done we know that

W = F.d

(9.0 \times 10^{-4}) = F(0.15)

F = 6 \times 10^{-3} N

Direction of force is along the motion of charge

Part b)

As we know the relation between electrostatic force and electric field given as

F = qE

(6 \times 10^{-3}) = 1.5 \times 10^{-6} E

E = 4000 N/C

direction of electric field is along the direction of motion
