Explanation:

IMAGE1: Projection of a on b (a1), and rejection of a from b (A2).

IMAGE2: When 90° < θ ≤ 180°, a1 has an opposite direction with respect to b.

The vector projection of a vector a on (or onto) a NONZERO vector b (also known as the vector component or vector resolution of a in the direction of b) is the orthogonal projection of a onto a straight line parallel to b.

Formula: proj(u)=(u.v/v.v).v

Answer:

(i) magnitude of potential ENERGY is greater than kinetic energy.

Explanation:

Because the VALUE of potential energy depend upon the VIRTUE of height.

The motion of an aircraft through the air can be explained and described by physical principals discovered over 300 years ago by Sir Isaac Newton. Newton worked in many areas of mathematics and physics. He developed the theories of gravitation in 1666, when he was only 23 years old. Some twenty years later, in 1686, he presented his three laws of motion in the "PRINCIPIA Mathematica Philosophiae Naturalis." The laws are shown above, and the application of these laws to aerodynamics are given on separate slides.

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external FORCE. This is normally taken as the definition of inertia. The key point here is that if there is no net force acting on an object (if all the external forces cancel each other out) then the object will maintain a constant velocity. If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force.

The SECOND law explains how the velocity of an object changes when it is subjected to an external force. The law defines a force to be equal to change in momentum (mass times velocity) per change in time. Newton also developed the calculus of mathematics, and the "changes" expressed in the second law are most ACCURATELY defined in differential forms. (Calculus can also be used to determine the velocity and location variations experienced by an object subjected to an external force.) For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a:

F = m * a

For an external applied force, the change in velocity depends on the mass of the object. A force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways.

The third law states that for every action (force) in nature there is an equal and OPPOSITE reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A. Notice that the forces are exerted on different objects. The third law can be used to explain the generation of lift by a wing and the production of thrust by a jet engine.

Answer:

SPEED=DISTANCE/TIME. To work out the speed of the sound in metres per SECOND, divide the distance in metres by the average time in seconds. For EXAMPLE 170 metres DIVIDED by 0.50 seconds = 340 m/s. You have CALCULATED the speed of sound!

The dimensions of a rectangular block measured with a vernier calliper having least count 0.01 cm or, 0.1mm is 4.0 MM × 10.0 mm × 10.0 mm.

we KNOW, formula of volume , V = LBH

using log both sides,

logV = log(lbh)

or, logV = logl + LOGB + logh

differentiating both sides,

or, dV/V = dl/l + db/b + dh/h

or, ∆V/V = ∆l/l + ∆b/b + ∆h/h

= 0.1/4 + 0.1/10 + 0.1/10

= 0.025 + 0.01 + 0.01

= 0.045

or, ∆V/V = 0.045

or, ∆V/V × 100 = 0.04 × 100 = 4.5%

or, % error in volume of rectangular box = 4.5%

Answer:

• Time = 5 secs
• Velocity = 10 m/s

Explanation:

Given that ;

Initial velocity (u) = 0

Acceleration (a) = 2 m/s²

Displacement(s) = 25 m

We will USE EQUATION of motion :

v² - u² = 2as

⇒ v² - 0 = 2 * 2 * 25

⇒ v² = 100

⇒ v² = (10)²

⇒ V = 10 m/s

Hence, the velocity of the car is 10 m/s.

_______________________

Again, using equation of motion ;

v = u + at

⇒ 10 = 0 + 2 * t

⇒ 10 = 2t

⇒ t =

⇒ t = 5 secs

_______________________

Hence, the time TAKE by car is 5 secs and the velocity acquired is 10 m/s.

•v = u + at

Let us BEGIN with the first equation, v=u+at. This equation only talks about the ACCELERATION, time, the initial and the FINAL velocity. Let us assume a body that has a mass “m” and initial velocity “u”. Let after time “t” its final velocity becomes “v” due to uniform acceleration “a”. Now we know that:

Acceleration = CHANGE in velocity/Time Taken

Therefore, Acceleration = (Final Velocity-Initial Velocity) / Time Taken

Hence, a = v-u /t or at = v-u

Therefore, we have: v = u + at

_____________________________•v² = u² + 2as

We have, v = u + at. Hence, we can write t = (v-u)/a

ALSO, we know that, Distance = average velocity × Time

Therefore, for constant acceleration we can write: Average velocity = (final velocity + initial velocty)/2 = (v+u)/2

Hence, Distance (s) = [(v+u)/2] × [(v-u)/a]

or s = (v² – u²)/2a

or 2as = v² – u²

or v² = u² + 2as

_____________________________•s = ut + ½at²

Let the distance be “s”. We know that

Distance = Average velocity × Time. Also, Average velocity = (u+v)/2

Therefore, Distance (s) = (u+v)/2 × t

Also, from v = u + at, we have:

s = (u+u+at)/2 × t = (2u+at)/2 × t

s = (2ut+at²)/2 = 2ut/2 + at²/2

or s = ut +½ at²

I hope it helps u

ANSWER:

this QUESTION is WRONG

EXPLANATION:

In an AC, or alternating current, Generator, the electrical current periodically reverses its direction. With a DC, or DIRECT current, Generator, the current flows only in one direction. The major difference between an AC Generator and a DC Generator is that the DC Generator REQUIRES a MECHANISM to provide a DC output

Answer:Not that It is not Daily Rates, It's the rate of Per UNIT Where 1 unit = 1 kWh (Also Called 1 =B.T.U = BOARD of TRADE Unit). for INSTANCE, If you switched ON a 1000 watt bulb for 1 hour, It mean you consumed 1000 watts for an hour i.e. (1000 watts for 1 hour = 1KWH = 1 unit of Energy).

i have been performed complex IMPEDANCE spectroscopy and want to know that how i can FIND dielectric constant (real and imaginary parts) from impedance

Explanation:

{eq}V = 21 \space V {/eq}

{eq}R_{1} = R_{3} = 3.8 \space \Omega {/eq}

{eq}R_{2} = R_{4} = 8.8 \space \Omega {/eq}

The CIRCUIT diagram can be simplified by taking the effective CAPACITANCE of {eq}R_{1}, R_{2}, {/eq} and {eq}R_{4} {/eq}. This is SIMPLY:

{eq}R_{1,2,4} = (\frac{1}{8.8} +\frac{1}{8.8})^{-1} + 3.8 {/eq}

{eq}R_{1,2,4} = 8.2 \space \Omega {/eq}

The other HALF of the resitors containing the {eq}12 \space \Omega {/eq} resistor:

{eq}R_{half} = (\frac{1}{4} +\frac{1}{12})^{-1} + 2.0 {/eq}

{eq}R_{half} = 5 \space \Omega {/eq}

The effective resistance of the whole circuit is therefore:

{eq}R_{eff} = (\frac{1}{5} +\frac{1}{8.2})^{-1} + 3.8 {/eq

HEIGHT OF COLUMN..

PROCEDURE:

◆Take a plastic bottle or a beaker which has tube LIKE structure.

◆Fill the CONTAINER full with water.

◆Now with any sharp object make holes to the container one by one from top to bottom.

◆You can observe that water flowing out from top holes are coming with LESS force and falling just infront of the beaker.But the water flowing out from bottom holes are coming with HIGHER force and falling far from container.

◆Repeat the same experiment with half filled container . you will notice change in FLOW of water outside.

Answer:

The PERCENTAGE error in the volume of the block is 0.011%

EXPLANATION:

According to the PROBLEM the length of the rectangular block  is l

l= 12.13(+-)0.02cm

BREADTH of the rectangular block  is b

b= 8.16(+--)0.01cm

height of the rectangular block  is h

h= 3.46(+-)0.01 cm

therefore the volume will be,

v= lbh =(12.13+0.02)(8.16+0.01)(3.46+0.01)

        =342.47+0.04 cm^3

Percentage error can be find subtracting theoritical RESULT with from the experimental.

therefore,

%error= (Vexperimental−Vtheoritical)/Vtheoritical

             =342.47−(342.47+0.04)/(342.47+0.04)

            =0.011%

Answer:

0.8

Explanation:

as x is given 40 CM which is EQUAL to half oscillation/half WAVELENGTH, the double of 40 CM is wavelength size, i.e. 80CM is wavelength.

also standard UNIT of measurement of wave length is meters, so wavelength is 80/100, i.e. 0.8 meters

ANSWER:

EXPLANATION:

It's ACCELERATION is 5m/s^2

It COVER 30 m

Answer:

distance=15cm

displacement=0cm

Explanation:

the body took 3 ROUNDS so 1ST round is 5cm and the other 2 rounds of 5cm each, then the total is 15 cm, so distance is 15cm and because the path is CIRCULAR the body TAKES a round and again comes back to the initial position, so the displacement is 0cm.
