Explanation:

As from the expression of power..

We know.

PRESSURE = Force / area

So we conclude

Pressure is DIRECTLY proportional to Force.

Thus, as force increases the pressure ALSO increases.

Thermal conductivity MEASURES the ability of a metal to conduct heat. This property varies across different TYPES of metal and is important to consider in applications where high operating TEMPERATURES are common.

In pure metals, thermal conductivity stays roughly the same with increases in temperature. However in alloys the thermal conductivity increases with temperature.

Which Metals Conduct Heat The Best?

Common metals ranked by thermal conductivity

ANSWER:

Ordinary air pressure is the weight of a column of air that extends to the top of the Earth's atmosphere divided by the cross-sectional AREA of the column. Air pressure can be measured using a MERCURY barometer.

In the case of a Mercury Barometer the pressure exerted by 760mm column of mercury is the same as that of a column of air extending to the top of the atmosphere. Thus my measuring the height of column of mercury one can measure the pressure of the air. This method is not in much use these days because Mercury is considered a bio-hazard. One could use water instead of mercury except it would not be very practical since the a column of water that will equal that of air pressure is 10.3m high.

Hence, The atmospheric pressure can SUPPORT 10.3 m vertical height of water .

Perfect question

An object is starting from rest and moving with an acceleration of 2m/s² . What will be its velocity after 10 seconds ?

Answer

GIVEN :

Initial velocity = Zero. (object in rest)

Acceleration of the object = 2m/s².

Time = 10sec.

To find :

Final velocity of the object.

Solution :

As we are providing with Initial velocity, accerlation and time, we can use 1st equation of

MOTION .i.e.,

• v = u + at

where,

v denotes final velocity

u denotes initial velocity

a denotes acceleration

t denotes time

So, using first equation of motion,

➠ v = u + at

➠ v = (0) + (2)(10)

➠ v = (2)(10)

➠ v = 20m/s

thus, velocity after 10 seconds is 20m/s.

Some RELATED equation of motion :

1st equation of motion : v = u + at

2nd equation of motion : s = ut + 1/2 at²

3rd equation of motion : v² = u² + 2as

Answer:

The mechanical advantage of the lever is the ratio of output FORCE to input force, This relationship shows that the mechanical advantage can be COMPUTED from ratio of the DISTANCES from the fulcrum to where the input and output forces are applied to the lever, assuming no losses due to friction, FLEXIBILITY or wear.

The first part of the motion is the motion with constant acceleration at . The initial velocity for this motion is 80 m/s. Then we can WRITE the equation, which DESCRIBES the dependence of height of the rocket on time:

From this equation we can find the time when the rocket reaches the height 1000 m = h:

The solution of this equation is 10 s. So after 10 seconds, the engine fails. The velocity at this moment of time is

After this moment of time we have free fall motion – there is only one force acting on the object (it is gravitational force) – this force provide free fall acceleration.

The initial velocity is 120 m/s pointing upward. The acceleration is pointing downward. The initial height of the rocket is 1000 m. Then the equations which describe this motion are the following:

To find the maximum height of the rocket we can use the last equation. The velocity at the maximum height is 0. Then

To find the time when the rocket hits the ground we NEED to use the first equation:

When the rocket hits the ground h=0. Then

From this equation, we can find time: 31 s.

Then we can find the time when the rocket is in the air: it is the sum of the time when it reaches 1000 m and the time when it hits the ground:

To find the speed of the rocket when it hits the ground we need to use the last equation:

When the missile hits the ground h=0. Then

Answer:

PLANE mirrors and CONVEX mirrors will always produce an UPRIGHT IMAGE. A CONCAVE mirrorwill only produce an upright image if the object is located in front of the focal point.

Wormhole theory

Wormholes were first theorized in 1916, though that wasn't what they were called at the time. While reviewing another physicist's solution to the equations in Albert Einstein's theory of general relativity, Austrian physicist Ludwig Flamm realized another solution was possible. He described a "white hole," a theoretical time reversal of a black hole. Entrances to both black and white holes could be connected by a space-time conduit.

In 1935, Einstein and physicist NATHAN Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of "bridges" through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance. The shortcuts came to be called Einstein-Rosen bridges, or wormholes.

Einstein's field equations hit physics like a tsunami in 1915, and theorists are still sorting through the wreckage. Beyond describing the force of gravity, his HYPOTHESES also brought a paradigm-shattering message about the nature of reality. More than a rigid backdrop, space and time bend and fold along with the mass of stars and planets. That insight sparked a race to calculate just how much abuse space could take from the matter that drifts through it.

Within a year, physicist and astronomer Karl Schwarzschild found the first exact solution to Einstein's equations, calculating how space-time curves around a single ball of mass. In his answer lay the seeds of what physicists today call a singularity — a spherical mass shrunken down to an infinitely dense point, wrapping space around it so tightly that the region pinches off from the rest of the universe. It forms a no man's land whose event HORIZON fractures the link between cause and effect.

Black holes, the most famous singularities, are regions of space so warped that no exits exist. The OUTSIDE universe can influence the inside of a black hole's horizon, but the interior can't affect the exterior.

the difference between two positive INTEGERS is 50

the ratio of these INTEGERSE 1:3

These Integers

.

Let,

First Integers = x

Second Integers = y

Case 1.

(the difference between two positive integers is 50)

↪ x - y = 50 ___________(1)

Case 2.

(the ratio of these integerse 1:3)

↪ x : y = 1: 3

↪x/y = 1/3

↪3x - y = 0 _____________(2)

Subtract equ(1) & equ(2)

↪ x - 3x = 50

↪-2x = 50

↪x = -50/2

↪x = -25

Keep Value of x in equ(1)

↪ -25 - y = 50

↪y = -25 - 50

↪y = -75

According to question, both Integers are positive , so NEGLECT NEGATIVE sign by all values.

.

First Integers will be = 25

Second Integers will be = 75
