A particle makes 240 revolution per minute on a circular radius of 2m find: (1) it's period (2) it's angular velocity (3) it's linear velocity (4) it's acceleration
Answer:
(1) The period 0.25 secs
(2) The angular velocity is 25.14 rad/s
(3) The linear velocity is 50.28 m/s
(4) The acceleration is [tex]1264 m/s^{2}[/tex]
Explanation:
(1) Period is defined as the time taken for one revolution
∴ [tex]Period = \frac{Time }{Number of revolutions }[/tex]
From the question, the particle makes 240 revolution per minute
That is, For 240 revolution, the time taken = 1 minute
Time = 1 minute = 60 secs
Number of revolutions = 240
∴ [tex]Period =\frac{60}{240} \\[/tex]
Period = 0.25 secs
The period 0.25 secs
(2) The angular velocity, ω is given by
ω [tex]= \frac{2\pi }{T} \\[/tex]
where [tex]T[/tex] is the period
∴ω = 2 ×[tex]\frac{22}{7}[/tex] / 0.25 (take [tex]\pi = \frac{22}{7}[/tex])
ω = 25.14 rad/s
The angular velocity is 25.14 rad/s
(3) The linear velocity, v is given by
v = ωr
Where v is the linear velocity
ω is the angular velocity
and r is the radius
From the question, r = 2m
From v = ωr
∴v = 25.14 × 2
v = 50.28 m/s
The linear velocity is 50.28 m/s
(4) The acceleration is given by
[tex]a =[/tex] ω × v = ω(ωr) =ω²r
∴ [tex]a = 25.14^{2}[/tex] × [tex]2[/tex]
[tex]a = 1264.04 m/s^{2} \\a = 1264 m/s^{2}[/tex]
The acceleration is [tex]1264 m/s^{2}[/tex]

How are electromagnetic spectrum or waves different from other waves?
Answer:
Electromagnetic spectrum is the arrangement of all kinds of radiation according to their frequency and wavelength. They don't require a material medium for their propagation.They are transverse waves that travel in a direction perpendicular to the direction of vibration.
what a measurement standard is defined as?
Answer:
Measurement is the competion of known quantity to unknown quantity.
Explanation:
I hope that it will be right answer
Answer:
Measurement standard is relationship of a physical quantity.
Explanation:
Measurement standard is the fundamental reference and measuring the compared the device, these reference is controlled to the objects conditions to the physical quantity.
Measurement standard are international and perfect master standard and they can not used to the general purpose, there are following categories are:-(1) primary standards (2) secondary standard (3) working standard.(1) primary standard is also known as the master standard to the careful conditions, they are used to the long internals only and they compare to the secondary standard.(2) Secondary standard is also known as the primary standard these type of standard are compared to the regular intervals, and distribute to the safe custody.(3) Working standard is also used to the workshop and laboratories by the worker these are to used in the materials reduce cost.Measurement standard is the need of working to the standards in based to the international standard system.when is your weight is equal to mg?
Answer:
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg.
Answer:
Weight is always equal to mg.
as we know the formula
Weight=mass(m)× acceleration due to gravity (g)
Your may may be when our weight is equal to Zero.
Our weight is zero:1) at the center of the earth because value of g is 0 there
2)in the space at null point
3)during weightlessness

Time (t) being in which body remains in air = 4 seconds
Why did Hubble's data change our view of the universe?
Answer:
Hubble has helped survey galaxies that existed when the universe was only 600 million years old. Previous estimates had suggested that galaxies didn't form until the universe was at least two billion years old. The instrument's images have helped scientists understand how galaxies evolve.

A ship coming from sea enters the river ,with its hull sink more or less in river water?Give reasons.
Explanation:
Hey, there!
Answer: It sinks more.
We know that the water of sea is salty in nature which increases the density of water in sea and donot let's ship sink but in condition of river water it doesn't have any effects of salty water as it doesn't contain salty water due to which it's density is no more than the densityof ship which let's it sink more than sea water.

Answer:
The correct answer is option b and c.
differences between work against friction and work against gravity.
Friction is the force that is resisting the motion of an object so it will always point in the opposite direction of that of movement. ... The force of gravity points downwards . So when you do work against gravity it means that the force acting on that object points in the upward direction .

When is elastic potential energy stored and when is it released in: a toy glider launcher the elastic cords or springs beneath a sun-lounger a diving board?
Answer:
Explanation:
Assuming a toy glider works on a spring potential energy is stored when the spring(launcher) is fully compressed..and is released when the spring is released.
Potential Energy is stored when the diver has stepped on the board, and the board is at the bottom of its movement, and is released when the diver jumps off.

force of earth is 6 into 10 to the power 24 Kg 1 kg-iii 6.4 find the force
Answer:
Explanation:
Here is the answer---
Given Conditions ⇒
Mass of the Earth(m₁) = 6 × 10²⁴ kg.
Mass of the Moon(m₂) = 7.4 × 10²² kg.
Distance between the Earth and the Moon(d) = 3.84 × 10⁵ km.
= 3.84 × 10⁸ m.
Gravitational Constant(G) = 6.7 × 10⁻¹¹ Nm²/kg².
Using the Newton's law of Gravitation,
F = G × m₁× m₂ × /d².
F is the Force of Gravitation between the Earth and the Moon.
Substituting the Given Values in the Formula,
∴ F = (6.7 × 10⁻¹¹ × 6 × 10²⁴ × 7.4 × 10²²) ÷ (3.84 × 10⁸)²
⇒ F = (6.7 × 6 × 7.4 × 10¹⁹) ÷ (14.7456)
⇒ F = 20.1741 × 10¹⁹ N.
⇒ F ≈ 20.2 × 10¹⁹ N.
Thus, the Gravitational Force of Attraction between the Earth and the Sun is 20.2 × 10¹⁹ N.

A U-tube is open on both ends and partially filled with water. Benzene (does not mix with water, density = 897 kg/m3) is poured into one arm forming a column of benzene 4 cm high. What is the difference in height between the two columns of water?
Answer:
0.459cm
Explanation:
Using
Po+ (L + h1) dBg= Po + Lx DW xg
So
h1= L( dw/dB-1)
= L( 1000/897-1)
= 4cmx 0.114
h = 0.459cm
Starting at point 0, you travel 500 m on a straight road that slopes upward at a constant angle of 5 degrees. What is your height above the starting point? Answer in meters to the nearest centimeter
Answer:
43.58 m
Explanation:
If you travel 500 m on a straight road that slopes upward at a constant angle of 5 degrees
Using trigonometry ratio
Sin 5 = opposite/hypothenus
Where the hypothenus = 500m
Opposite = height h
Sin 5 = h/500
Cross multiply
500 × sin 5 = h
h = 500 × 0.08715
h = 43.58m
Therefore, the height above the starting point is equal to 43.58m

is changing from 145 m/s to 75m/s?
A. 4.67 m/s
B. 3.4 m/s
C. 45 m/s
D. 23 m/s
Answer:
A. 4.67 m/s²
Explanation:
u = 145 m/s
v = 75 m/s
t = 15 s
a = v - u / t
= 145 - 75 / 15
= 4.67 m/s²

Answer:
. The branch of medical science called PHYSIOLOGY considers the functions of anatomical parts, whereas ANATOMY describes the form and organization of body parts.
Explanation:
THIS is because Anatomy the branch of life studyconcerned with the study of the structure of organisms and their parts
Whilw physiology studies the functioning of these parts
The branch of medical science that considers the functions of anatomical parts is called physiology, whereas anatomy describes the form and organization of body parts.
Physiology is the study of how body parts function and work together to maintain life processes and perform specific tasks. It focuses on the mechanisms and processes that underlie bodily functions, such as digestion, circulation, and muscle contraction.
On the other hand, anatomy is concerned with the structure, shape, and organization of body parts, including organs, tissues, and cells.
Together, anatomy and physiology provide a comprehensive understanding of the human body and its intricate workings, helping medical professionals diagnose and treat illnesses and maintain overall health.
Therefore, The branch of medical science that considers the functions of anatomical parts is called physiology.
