Answer :

• Ratio of the gravitational potential energy of the two bodies = 1 : 2

Explanation :

GIVEN :

• Mass of the both the bodies, m₁ = m₂ = m
• Height of the first body, h₁ = h
• Height of the SECOND body, h₂ = 2h
• Acceleration due to gravity, g = 10 m/s².

To FIND :

• Ratio of the gravitational potential energy of the two bodies.

Knowledge required :

Formula for Potential energy of a body :

⠀⠀⠀⠀⠀⠀⠀⠀⠀P.E. = mgh

Where,

• P.E. = Potential energy of the body.
• m = Mass of the body.
• g = Acceleration due to gravity acting on the body.
• h = Height at which the body is kept.

Solution :

First LET us find the Potential energy of the body at height of h.

By using the formula for potential energy possessed by a body and substituting the values in it, we get :

⠀⠀=> P.E. = mgh₁

⠀⠀=> P.E. = m × 10 × h

⠀⠀=> P.E. = 10mh

⠀⠀⠀⠀⠀⠀∴ P.E. = 10mh

Hence the potential energy possessed by the body at HIEGHT = h, is 10mh

Now let's find out the potential energy possessed by the body at height of 2h.

By using the formula for potential energy possessed by a body and substituting the values in it, we get :

⠀⠀=> P.E. = mgh₁

⠀⠀=> P.E. = m × 10 × 2h

⠀⠀=> P.E. = 20mh

⠀⠀⠀⠀⠀⠀∴ P.E. = 20mh

By comparing them, we get :

⠀⠀=> P.E.₁/P.E.₂

By substituting the values in it, we get :

⠀⠀=> P.E.₁/P.E.₂ = 10mh/20mh

⠀⠀=> P.E.₁/P.E.₂ = 1/2

⠀⠀=> P.E.₁ : P.E.₂ = 1 : 2

⠀⠀⠀⠀⠀⠀⠀∴ P.E.₁ : P.E.₂ = 1 : 2

Hence the ratio of the potential energy possessed by the body at height , h and 2h is 1 : 2.

OPTICALLY DENSER MEDIUM :

• It is the medium in which the light TRAVELS SLOWLY than other MEDIUMS is called a optically denser medium.

• Optically denser medium have the large refractive index.

OPTICALLY RARER MEDIUM :

• It is the medium in which light travels in more speed than optically denser medium.

• Optically rarer medium have the lower refractive index than the optically denser medium.

Given :-

VELOCITY of the car travelling = 20 m/s

Mass of the car = 1050 kg

To Find :-

The KINETIC energy of the car.

Analysis :-

Here we are given with the velocity and mass of the car.

In order to find the kinetic energy substitute the values such that kinetic energy is equal to one by two MULTIPLIED by mass and velocity.

Solution :-

We know that,

• KE = Kinetic energy
• m = Mass
• v = Velocity

Using the FORMULA,

Given that,

Velocity (v) = 20 m/s

Mass (m) = 1050 kg

Substituting their values,

⇒ KE = 1/2 × 1050 × 20²

⇒ KE = 1/2 × 1050 × 400

⇒ KE = 1050×400 / 2

⇒ KE = 420000 / 2

⇒ KE = 210000 J

Therefore, the kinetic energy of the car is 210000 J.

Answer:

Pressure is the amount of force APPLIED perpendicular to the surface of an object PER unit AREA and the for it is p (or P). The SI unit for pressure is the PASCAL (Pa), equal to one newton per SQUARE metre (N/m2, or kg·m−1·s−2).

FINAL ANSWER:

5 kg

GIVEN:

body gets 10 meter per second

doing work of 500 joules

h = 10 meters

m = ?

G 10 m/s

PE = 500 J              or                  Wd = 500 J

TO FIND:

MASS of the body

FORMULA USED:

PE = m×g×h

SOLUTION:

As the object gets closer to the GROUND, its potential energy decreases while its KINETIC energy increases .

∴ PE = m×g×h

  500 = m×10×10

  500 = 100×m

      m =

      m = 5 kg

• Writing would be impossible.

• All sports events would be pointless.

• Cars would not WORK Beacuse brakes also would become usless.

• Matches would not work.You would not be able to rub them.

• But, all the spinning machines would work properly.

• One advantage, your computer would work without overheating.This would lead to massive improvement in technology.

• Phone audio quality would be a lot better, as friction would not have any effect on telephone cables.

Answer:

Deer are adapted to different environments in a few ways. First of all and most important in colder regions, they have a reddish brown coat in late spring and summer MONTHS. Coming into winter they shed this coat and grow a new THICKER coat, this one more tan/grey, which helps with camouflaging themselves. But most importantly, the coat insulates them from cold environments, with the longer hair within the blanket of fur being hollow, providing them with a LAYER of insulation. They have very strong LEGS and can run over 25 mph on average, when need be. These strong leg muscles are used to jump over things in their way and what not as well as run from possible danger. Deer have a heightened sense of smell and hearing compared to humans and are very good at trusting their instincts when they get the FEELING they should run. Smaller adaptations, which may change a few times in a deer's life span, are ones such as bedding and mating locations and food type and sources. These may be changed or adjusted for many reasons, ie: new predators in the area, human population growth in the area forces them to assimilate or relocate, or simply that their original location wasn't providing them with what they needed anymore. I know that there is a lot more to it than that but that is a basic generalized “summary" I guess you could say.

THANKS MY ANSWERS PLZZ

ANSWER:

both Km/h and m/s are INTERLINKED with each other as if meter increases than km also increases . if s increases or decreases than hour will also effect .

we can say that ,

                   Km/h ∝ m/s

∴ km/HR = 1 km/1 hr = 1 × 1000 m/60 × 60 SEC = 1000/3600 m/sec = 5/18 m/sec                                

So, we say that to convert km/hr into m/sec, we multiply by 5/18.

Answer:

One of my favorite classes to teach is Physics for Elementary Education. It's a physics class DESIGNED to address the needs of future elementary school teachers—grades 1 through 6 or so. To guide the class, I've been using a version of Next Gen Physical Science and Everyday Thinking for a long time, maybe 13 years or so, and it is super awesome.

One of the major goals in this course is to help students understand the NATURE of science—in particular the idea that science is all about BUILDING and testing models. Throughout the course, the students collect data and build models of their own, but they also learn about existing scientific models, LIKE the heliocentric (sun-centered) model of the solar system.

Answer:

Any matter that is a SOLID has a definite SHAPE and a definite volume. The MOLECULES in a solid are in FIXED positions and are close TOGETHER

Earth is the only planet in the Solar System KNOWN to support life. This is because we are at just the right DISTANCE from the Sun so that our planet doesn't GET too hot or too cold. We also have one moon – the Moon. Mars – Mars is the FOURTH planet from the Sun, and is much SMALLER and colder than the Earth.

Answer:

SOLID has definite volume and shape, a LIQUID has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. FIGURE 3.3. 2: A Representation of the Solid, Liquid, and Gas States. (a) Solid O2 has a FIXED volume and shape, and the molecules are PACKED tightly together.

Answer:

VELOCITY is a vector expression of the DISPLACEMENT that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (ALSO known as speed ) is the METER per second (m/s). Alternatively, the centimeter per second (cm/s) can be USED to express velocity magnitude.

ANSWER:

YES ......................

Explanation:

Given,

Diagonals are equal

AC=BD .......(1)

and the diagonals bisect each other at right angles

OA=OC;OB=OD ...... (2)

∠AOB= ∠BOC= ∠COD= ∠AOD= 90

0

..........(3)

Proof:

Consider △AOB and △COB

OA=OC ....[from (2)]

∠AOB= ∠COB

OB is the common side

Therefore,

△AOB≅ △COB

From SAS criteria, AB=CB

Similarly, we prove

△AOB≅ △DOA, so AB=AD

△BOC≅ △COD, so CB=DC

So, AB=AD=CB=DC ....(4)

So, in quadrilateral ABCD, both pairs of opposite sides are equal, HENCE ABCD is PARALLELOGRAM

In △ABC and △DCB

AC=BD ...(from (1))

AB=DC ...(from $$(4)$$)

BC is the common side

△ABC≅ △DCB

So, from SSS criteria, ∠ABC= ∠DCB

Now,

AB∥CD,BC is the tansversal

∠B+∠C= 180

0

∠B+∠B= 180

0

∠B= 90

0

Hence, ABCD is a parallelogram with all sides equal and one angle is 90

0

So, ABCD is a square.

Hence proved.
