Answer:

Explanation:

LET e1 and e2 be two given unit vectors. Let their SUM give unit vector e3. Therefore ,

e1+e2=e3.

Squaring on both SIDES,

e1^2 + e2^2 +2e1e2 cos (theta)=e3^2. Here, ( theta) is angle between e1 and e2.

Substituting the magnitudes,

1 + 1 +2(1)(1) cos ( theta)=1.

Therefore , cos (theta)=-(1/2).

Therefore ,

(Theta)= 120 degree.

Now, we calculate MAGNITUDE of difference of e1 and e2.

| e1- e2|= sqrt[e1^2-(2)(1)(1)(-1/2) +e2^2]=sqrt[ 1+1+1]= sqrt of (3)

Answer:

60 kmph

Explanation:

1st CASE:

distance= 20km

speed=40kmph

TIME=distance/speed

=20/40

= 1/2 hr

2nd case:

distance=40km

speed=80kmph

time = 40/80=1/2 hr

hence, for equal time,

AVERAGE speed:-

(speed1+speed 2) /2

=(40+80) /2

=120/2

= 60kmph.......(ANS)

ANSWER:

The SOUND do not DEPEND because

Explanation:

The sound do not have mass . if an object having mass the PRESSURE will appear. so sound do not depend

on pressure

first i will tell u the 3rd LAW as its very simple...XD

'every action has an equal and opposite reaction'

for ex: FIRING a bullet

action: bullet leaving the pistol

reaction: force experienced by the man holding the gun

1st law states that also known as law of inertia

'a body in the state of motion or in the state of rest will remain in the same state until an external unbalanced force is applied'

Ex : a man sitting in a bus MOVES forward when BRAKES are applied by the driver. (as if his base is stuck with the seat of the bus...XD)

hope this helps and PLZ do not mind my jokes cause my teacher taught me like that.

ANSWER:

v=20m/s

Explanation:

Answer:

E=mc^2 - Deriving the EQUATION - Easy. When Einstein first PROPOSED his SPECIAL Theory of Relativity in 1905 few people understood it and even fewer believed it. It wasn't until 1919 that the Special Theory was "PROVED by inference" from an experiment carried out on his General Theory of Relativity.

ANSWER:

SEARCH on the GOOGLE OK .

this statement is false as the DISPLACEMENT can be ZERO

a particle MOVING in a circular path will return to its original position after COMPLETING one round.

In this case displacement becomes zero.

ANSWER:

The flow of energy in the ECOSYSTEM isunidirectional because the energy lost as heat from the living organisms of a food CHAIN cannot be reused by plants in PHOTOSYNTHESIS. During the transfer of energy through successive trophic levels in an ecosystem, there is a loss of energy all along the PATH.

ANSWER:

Because the magnetic flux is PROPORTIONAL to the instantaneous current, while the emf is proportional to the >RATE of change< of the current.

EXPLANATION:

The balancing of rotating BODIES is important to avoid vibration. ... In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre of ROTATION.

Answer:

the application of HC for biodiesel production is undeniably NOVEL in this area. Only a few studies have been done in biodiesel production using HC approach as DEPICTED in Table 3. HC for biodiesel synthesis from vegetable has been explored a decade ago by pioneering work of Ji et al. (2006) in 2006. ...

it is no doubt that HC was efficient, referring to YIELD efficiency. The yield efficiency was SHORTENED in the order of HC, MW, UC and MS (Table 3). ...

Answer:

The protons, however, are produced using a similar technique to the CRT – in this case with an ion SOURCE known as a duoplasmatron. A cathodefilament emits electrons into a vacuum chamber CONTAINING SMALL amounts of hydrogen gas. The protons are then confined by magnetic fields and accelerated to become a beam.

Explanation:

The BOOLEAN expression for a LOGIC NAND gate is denoted by a single dot or full stop symbol, ( . ) with a line or Overline, ( ‾‾ ) over the expression to SIGNIFY the NOT or logical negation of the NAND gate giving us the Boolean expression of: A.B = Q.

Answer:

1440 C

Explanation:

ACCORDING to the given QUESTION,

I = current = 0.4 A

t = time = 1 h = 3600 s

q = charge = ?

And we are ASKED to find the amount of charge.

We know,

• I = q/t

• q = I × t

Putting the values we get,

• q = 0.4 × 3600

• q = 1440 C

Thus amount of charge is 1440 C when current is 0.4 A and time is 1 hr.

Answer:

Two Requirements for TOTAL Internal Reflection. Total internal reflection (TIR) is the phenomenon that involves the reflection of all the incident light off the BOUNDARY. The light is in the more dense medium and APPROACHING the less dense medium. the angle of incidence is greater than the so-called critical angle.

EXPLANATION:

HYDROSTATIC pressure refers to the pressure exerted by a fluid (gas or liquid) at any point in SPACE within that fluid, assuming that the fluid is incompressible and at rest. Pressure within a liquid DEPENDS only on the density of the liquid, the acceleration due to gravity, and the depth within the liquid.

This STATEMENT is absolutely TRUE as FORCE is a vector QUANTITY therefore its sure that it will have some particular direction.

Therefore your answer is True.
