A bullet of mass 10 gram is fired from a gun of mass 8 kg with a velocity of 160m/s.Find the velocity of recoil of gun.Find force required to stop the gun in a distance of 25 cm.-before fire,u1(veloci
How do i convert 50ps to Gs??
Convert 200MW to mW??-50 ps = 50*10^-12 s =(50*10^-12)*{(10^-9)*(10^9)} s = (50*10^-12)*{(10^-9)}{*(10^9)} s(50*10^-12)*{(10^-9)}G s = 5*10^-20 Gs
200MW = 200*10^6 W =
On an inclined plane, sometimes the force applied is up the incline,sometimes its down the incline BUT sometimes its stationary. My question is, when do you ADD the Rn value with mgsintheta and when d
A bullet of mass 20 gram travelling with a velocity of 16m/s penetrates a sand bag and is brought to rest in 0.05 seconds.Find the depth of penetration and average retarding force of the sand.-Impulse
If white light passes through slits, colored fringes may be observed.
What phenomenon is responsible for this?-Well, your question contains the answer!! Diffraction!!
Different wavelengths are diffrac
How do you estimate the gravitational force which the Moon exerts upon your body while we are on the surface of the Earth?
From the first answer how do you go about answering it as a percentage of yo
A man performs in a room with a ceiling 1.85 m above hand level. What is the maximum upward speed (in m/s) which he can give a ball without letting it hit the ceiling?-Use the kinematics eq;

1) The specific heat of water is one of the highest of all substances. Why does this make water a useful liquid to use in hot water bottles?
2) Could you use a lump of metal to warm your bed instead
electron exist with companion to its anti electron. How about other virtual particle like gluon does it exist with companion to his antiparticle-No. Electrons arent created at all, they just are. If a
Im looking for about 1L to 2 Litres worth. Ive been looking at SAE motor oil but its pretty expensive. 5 liquids of varying viscosity would be optimal. Nothing too thick like honey, it has to flow out
How is white light in diffraction different to white light shining into a prism to show colours?-White light shining into a prism shows colours because of dispersion or splitting of white light. In di
Nothing in science is certain. It may be extremely probable but nothing is 100%-In answer to UR 2nd question there used to be a standard answer
death and taxes :>)
Help me ! -It is called atom. But only up to that. Beyond that we do not know, whether it is tiny or not. For example, electron which is contained in Hydrogen atom cannot be considered as tinier than
Your friend reasons that if ultraviolet light can
activate the process of fluorescence, infrared
light should also. Your friend looks to you for
approval or disapproval of this idea.
