option (c) is the right answer

Apption C is correct

U = 19.6m/sg= -a ( because it works downward)v= u+at(took a=g=10)19.6+10*239.6m/s- answer

value of g is negative

the gravity acts in downward direction.. havung value (9.8m/s²) ↓

An object is thrown upward then ,final velocity (v)=0 ,initial velocity (u)=3m/s,time (t)=5sec.Height (s)=?To find S, we find acceleration V=u+at0=3+a×5-3=5a-3/5=ausing second equation of motion S=ut+1/2×a×t square S=3×5+1/2×-3/5×5 squareS=15-3/10×25S=15-15/2S=30-15÷2S=15/2S=7.5m/s

Force is in same direction and of same magnitudeit would be added up as 50 + 50 is equal to hundred Newton of force= 100N

no correct sister

we should take components of gravitational force

answer is 12N when we draw fbd N=mgsinα

Some measure factor on which speed of sound(in air medium) depend are: 1.Temperature (velocity of sound is directly proportional to square root of temperature). 2. Pressure 3.Density(velocity of sound is inversely proportional to square root of density) 4.Humidity(Humid air have low density so that have higher velocity and vice versa).

loudness is determined by amplitude and pitch is determined by frequency. loudness is measured in decibels and pitch in hertz

Hypermetropia (long-sightedness) is a common eye condition where nearby objects appear blurred, but your vision is clearer when looking at things further away.

If you feel your eyes are often tired and you have problems focusing on objects close to your eyes, you may have hypermetropia.

Both myopiaand hypermetropia canbe easilycorrectedby the Optometrist at your local Vision Express, using prescription glasses or contact lenses specifically designedto. counteract their effects.

Longsightedness iscorrectedusing a convex (outward facing) lens.

Farsightedness, orhyperopia, occurs when an irregularly-shaped eye prevents light from properly lining up with the retina.

People of any age, including babies, can be farsighted.

Presbyopiais an age-related condition in which the lens of the eye becomes less flexible.

Option (D) is correct.

1.) LED Bulbs are energy efficient. 2.) These bulbs have long life. 3.) These bulbs are environment Friendly i.e, not emmit harmful radiations.

The velocity of image will have the same magnitude as that of velocity of child. The velocity of image will have a negative sign to indicate that the image is moving in a direction opposite to that of the child.

Velocity of image = - 5 km h⁻¹

There are two main types of mechanical energy. They aremotion energyand stored mechanical energy.Motion energy: This is the energy something has because it is moving (eg a speeding cricket ball).

minimum length=height/2=1.8/2=0.9m

1)Heatis a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy. To review, temperature is a measure of the ability of a substance, or more generally of any physical system, to transferheatenergy to another physical system.

2)Heat conduction(orthermal conduction) is the movement ofheatfrom one solid to another one that has different temperature when they are touching each other. For example, we can warm our hands by touching hot-water bottles. ... Other ways to transferheatare bythermalradiation and/or convection.

Convectionisheattransfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source ofheat, carrying energy with it.Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law)

option (a) is correct.

When q1q2>0 then repulsiveWhen q1q2<0 then attractive

As like charge repel each other and unlike charge attract each other and product of like charge is always positive and product of unlike charge is negative

Mass of the earth (Me) = 6×10²⁴ Kg

Mean orbital radius of earth around the sun (r) = 6.4 × 10^6m

P.E of the rocket at earth's surface (Uo) = -GMem/Re

P.E of the rocket at height h from the earth's surface.

Uh = -GMem/(Re + h)

Increase in PE (∆U) = Uh-Uo

= -GMem/(Re + h) - (-GMem)/Re

= GMem[ 1/Re - 1/(Re + h)]

= GMem× h/Re(Re + h)

g = GMe/Re²

GMe = gRe²

∆U = gRe² × m×h/Re(Re+h)

= mgh/( 1 + h/Re)

According to law of conservation of energy .

Increase in P.E = KE of the rocket

1/2 × mv² = mgh/(1 + h/Re)

v²( 1 + h/Re) = 2gh

h = v²Re/( 2gRe - v²)

Here, v = 5 km/s = 5000 m/s

Re = 6.4 × 10^6 m g = 9.8 m/s²

h = (5 × 10³)²× 6.4×10^6/{ (2×9.8×6.4×10^6) - (5×10³)²}= 1600 km

Distance from the centre of the earth = h + Re = 6400 + 1600 = 8000 km = 8× 10^6m

The gallium column can be computed by the use of the defini­tion:(hGa) (dGa) = (hHg) (dHg)whereh = height of a column,d = density,therefore hGa = [{(hHg) (dHg)} / (dGa)]1 atm pressure = hHg = 760 mm Hg = 76.0 cm Hg. The density ofmercury = dHg = 13.6 gm/cm3 . Therefore, hGa = [{(76.0 cm Hg) (13.6 gm/cm3)} / (6.09 gm/cm3)] = 169.7 cm Ga = 1697 mm Ga
