Answer:

The equation of motion of S.H.M x=0.5cos(100+43π).

Comparing it with general equation motion of S.H.M, described as FOLLOWS, we get, x=Acos(ωt+θ)

(1) FREQUENCY= 2πω, Where ω=100= 2π

100 =(50π)Hz

(2)Initial phaseϕ= 43π

(3)Amplitude A=0.5cm

Maximum velocity=ωA=100×0.5=500m/s

(4)Maximum acceleration=ω 2A=100

2×0.5=50m/s 2

(5)TOTAL energy= 21 mω

2 A 2(Mass of the particle=0.1kg)= 21 ×0.1×(100) 2×(0.5) 2=125J

Answer:

Capillary tube is basically a expansion DEVICE looks similar to this . Expansion is required so that the refrigerant temperature while entering into evaporator COIL is less/low TEMP so that heat FLOWS from your room to the refrigerant in the coil and it boils.

ANSWER:

GASEOUS STATE of HYDROGEN ••••••••

Answer:

EXPLANATION:

Ocean thermal energy conversion (OTEC) uses the ocean thermal gradient between COOLER deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity.OTEC can operate with a very high capacity FACTOR and so can operate in base load mode.. The DENSER COLD water masses, formed by ocean surface water interaction

ANSWER:

V=IR.

I=200 mA=0.2A

R=20

so,V=0.01volt

Answer:

loudness is DIRECTLY proportional to (AMPLITUDE)^2

THE RMS SPEED OF HYDROGEN AT 25°C IS 1.93KM/S

The RMS speed which is the root mean square speed of NAY gaseous molecule is given by:-

                                     V=

• WHERE R= universal gas constant=

• T = Temperature

• M= Molecular weight of gaseous molecule

• In this QUESTION we have to CALCULATE this speed for hydrogen molecule

• M = 0.002 kg/mol

• T = 273+27= 300 K

• Putting above in formula  we get  V= 1.93 km/s

Answer:

when ASCENDING more apparent weight felt

when LIFT DESCENDING less apparent weight felt

Explanation:

Answer:

Because of scattering of LIGHT.

Explanation:

Water vapours which constitute the clouds are large enough to ABSORB MONOCHROMATIC light they is white light.

Thus it SCATTERS white light and it appears to be white

Answer:

The mass of an OBJECT is a measure of the object's inertial PROPERTY, or the amount of matter it contains. The weight of an object is a measure of the FORCE exerted on the object by gravity, or the force needed to SUPPORT it. The pull of gravity on the earth gives an object a downward ACCELERATION of about 9.8 m/s2.

1 When a carpet is beaten with a stick, the dust comes out of it because of law of INERTIA. Initially the dust particles are at REST along with the carpet. Beating the carpet with the stick makes the carpet to move but the dust particles REMAIN at rest DUE to inertia at rest, thus the dust gets DETACHED from the carpet.

ANSWER:

when TORQUE is MAXIMUM

Explanation:

When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, CALLED a CHANNEL. Once then light is GONE the air COLLAPSES back in and creates a sound wave that we hear as thunder. The REASON we see lightning before we hear thunder is because light travels faster than sound!

The answer will be 10

Explanation:

According to the problem the capacitance of the parallel plate is 100 pF

The thickness of the SHEETS is given as 1 mm

The dielectric CONSTANT of the paper is given

Now let the number of foils required is p and it will need (p-1) capacitors

Now let the dielectric constant is K

Therefore the capacitance is given by

c = ke0(p-1)A/d

=> (p-1) = cd/ke0A = cd/k x 4πe0A = 4π/πr^2 =  4cd/ k x 4πe0r^2

                 = 4 x 10^(-1) x 1 x 10^(-3) x 9 x 10^9/4(1.0 x 10^(-2))^2 = 9

p = 10

Explanation:

ICAP×jcap=kcap

then,,,,,icap.(icap×jcap)=icap.kcap

as we KNOW that

icap.icap=jcap.jcap=kcap.kcap=0

so icap.icap=0

i.e,,,icap.(icap×jcap)=0

Answer:

The AVERAGE speed is 2.7m/s APPROXIMATELY.

EXPLANATION:

First speed = 3m/s

Second speed = 2m/s, and

Third speed = 3m/s

Average speed = Total DISTANCE / Time taken

= 3m + 2m + 3m/ 1s + 1s + 1s

= 8m / 3s

Therefore, Average speed = 2.7m/s(nearly).

ANSWER:

The instantaneous VELOCITY of the ball at the TOP of its PATH is 0 m/s .

The acceleration at the top will be EQUAL to the acceleration due to gravity which equals to 9.8 m/s^2 .

Answer:

N = N0 E^-ct

N / N0 = .8 = e^-c      where t = 1 min   (c has units of 1 / min)

LN .8 =  -c

c = .223

N / N0 = 1/2 = e^(-t* .223)

ln .5 = -.223 t

t = .693 / .223 = 3.11 min = 186.6 sec

ANSWER:

VELOCITY is 2.19multiply106m/s=c137

ANSWER:mass×acceleration

Explanation:

ANSWER:

• Scattering OCCURS when light or other energy waves pass through an imperfect medium (such as air filled with particles of some sort) and are deflected from a straight path. The colours of light separate as the SUN's RAYS pass through the atmosphere, and blue is the colour that reaches us.
• Since blue light is at the short-wavelength end of the visible spectrum, it is more strongly scattered in the atmosphere than longer wavelength red light.

ANSWER:

Contact FORCES are forces which are caused by two objects touching each other. There are lots of DIFFERENT elementary forces which physicists study such as Electric and Magnetic (both of these are components of electromagnetic force), gravitational, and nuclear forces. Contact forces are a result of electric force.

In PHYSICS, action at a distance is the concept that an object can be moved, changed, or otherwise affected without being physically TOUCHED (as in mechanical contact) by another object. That is, it is the nonlocal interaction of objects that are separated in space.
