ANSWER:

It is called Inertia. According to Newton, and his first LAW of motion, and I quote, "The TENDENCY of undisturbed objects to stay at REST or to keep moving with the same velocity is called

Inertia.

but HOPE first answer will help u

ANSWER:

as wood is a solid PARTICLES in here are tightly PACKED . so it has a fixed shape.as attraction between particles a more THEREFORE we might get hurt when we move our hand

Explanation:

CA=40

O=16

Cl=35

Ca(OCl)Cl

Here

40+16+35+35=126 units

ANSWER:

increased by 2.

Explanation:

FORCE= m×a

thus , if UNIT of force and mass both are increased by 2 => a is constant

=> E= F×s , s is constant

=> ENERGY is increased by 2.

The magnetic moment of a current carrying coil is given by μ = niAk

Where,

n is the number of loops

i is the current throught the coil

A is the area of CROSS section of the coil

k is the unit vector along the direction of the magnetic moment

Since there is only one loop, n=1

Therefore,

μ =8*π(0.1)^2 k

=0.08π k

And to FIND k, imagine the coil in front of you such that the current in the coil is flowing in counter-clockwise direction (as seen by you)

Now curl your fingers along the circumference of the loop, you thumb will POINT in the direction of k which is ALSO the direction of the magnetic moment of the loop

Hope this helps ;)

Answer:

IMAGE FORMED would be REAL inverted and diminished

Explanation:

Answer:

2400000000 is the DISTANCE between SUN and EARTH by APPLYING the FORMULA of D = s * t

V = 5V

I = 100×10^-9 A

R = V/I

= 5/100×10^-9

= 5×10^7 ohm

P = VI

= 5×10^-7 W

ANSWER:

if light ray travells NORMAL there will be no change in the DIRECTION in any medium (rare to denser or denser to RARER)

Explanation:

d) 30 Ω

Resistance, R = frac{rho l}{A}

Length, l = 300 m

Cross-section area, A = 1.0 MM2 = 10-6 m2

Resistivity, rho = 1.0 × 10−7 Ωm

Resistance, R = frac{10^{-7} TIMES 300}{10^{-6}}

R = 30 Ω

Here, m=20g=20×10−3kg,

T=800N,l=1m

v1=12lTm−−−√=12×180020×10−3−−−−−−−−−√=2002=100Hz

Frequencies of HIGHER MODES of VIBRATION are

Ultrasound are the SOUNDS with frequencies more than 20 KHZ or 2000 HZ. INFRA sounds are the sounds with frequencies less than 20 Hz

Answer:

hey mate i am not able to write the formula that's why I am posting a pick of the formula for acceleration ok

Total velocity before increasing is 10km/hour=60m

Total velocity after increasing is = 15/60 .

final velocity = v1 and initial velocity =v2

Hey I have done this type of sum for the first time so plz CHECK my ans one's HA . because I am still in 8th standard

hey mate I think my ans is WRONG check for this one .

Initial velocity = U = 10 km /hr

= 10 x 5 /18

= 2.77777

= 2.8 m /s

Final velocity = V = 15 km / hr

= 15 x 5 / 18

= 4.16 m /s [ approx .]

Time = t = 6 sec

a = acceleration

Equation of motion :

v = u + at

4.16 = 2.8 + 6a

6a + 2.8 = 4.16

6a = 4.16 - 2.8

6a = 1.36

a = 1.36 / 6

a = 0.22 m /s.square

I = Q/t

I = 300 / (10×60)

I = 0.5 A

ANSWER:2CM

Explanation: its answer is 2cm

ANSWER:

UNIFORM MEANS same or EQUAL to other

non uniform means not equal

As PER Newton's third LAW of motion, action and reaction act on different BODIES. The MAGNITUDE of the force exerted by the bodies are EQUAL. However, the reaction is always opposite in direction. Both action and reaction are simultaneous in nature, that means there will be a reaction, till the action is taking place

Explanation:

GIVEN,

here, P is the pressure,

V is the volume

and  is the ABSOLUTE temperature.

we know, dimension of P =

dimension of V =

dimension of  = K

so, dimension of P = dimension of {a/V²}

dimension of P × dimension of V² = dimension of a

= dimension of a

= dimension of a,

dimension of a =

ANSWER:

An INCREASE in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic ENERGY. Answer: Because of heat the PARTICLES will MOVES fastly and Kinetic energy is increased so Kinetic energy of molecules in a substance depend on its temperature

1) 7.21 has THREE SIGNIFICANT figures.

Appropriate NUMBER = 7.2

2) 12.141 has five significant figures.

Appropriate number = 12.14

3) 2.45 has three significant figures.

Appropriate number = 2.4

4) 0.0028 = 2.8 ×10^-3 has two significant figures.

Appropriate number = 2.8 × 10^-3

Rules for Determining the Number of Significant Figures -

• All the non zero numbers are included as significant figures.

• A zero becomes significant if it comes between two non zero numbers.

• If any NOTATION is given in exponential form then the numerical portion is counted as the significant figure.

• A decimal can't change the number of significant figures.

all are correct.

Answer:

The Directory of the rule in France was a five-member commission which directed France from 1795 when it substituted the Public Safety committee. On 9 November 1799, it was abolished by Napoleon Bonaparte in the Revolution of 18 BRUMAIRE and substituted by the FRENCH Consulate.

The Directory was continuously at war with international alliances at various events including  Prussia, the Kingdom of Naples, Russia Britain, Austria, and the Ottoman EMPIRE. It also added Belgium to their territory while Bonaparte captured a substantial part of Italy. The Directory instituted 196 short-lived sister democracies created after France, in Rome, Netherlands, and Switzerland.

The Directory or Directorate (French: le Directoire) was a five-member committeewhich GOVERNED France from 1795, when it replaced the Committee of Public Safety. On 9 November 1799, it was OVERTHROWN by Napoleon Bonaparte in the Coup of 18 Brumaire and replaced by the French Consulate. It gave its name to the final four years of the French Revolution.
