tion:Voltage is the PRESSURE from an ELECTRICAL circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do WORK such as ILLUMINATING a light. In BRIEF, voltage = pressure, and it is measured in volts (V).

nothing Explanation:Heat is a FORM of kinetic energy … so all heat energy is kinetic energy, but not all kinetic energy is heat energy. Generally, heat is the kinetic energy stored MICROSCOPICALLY as random motion of MANY particles, while MECHANICAL kinetic energy is that stored as directed motion of objects

wo infinitely LONG parallel wires a and b carrying current of 10A and 20A respectively in opposite. direction are placed at a separation of 30 CM.To find:Position where the Magnetic field will be ZERO?Calculation:The required position (point P) will have the field intensity EQUAL and opposite to one another :So, point P is 30 cm from 10 Amp WIRE and 30+30 = 60 cm from 20 Amp wire.

friction FORCE is acting as opposite force which is balancing the block.now friction force on body ID less and force applied is force so it BECOMES an UNBALANCED force and starts moving.

Explanation The angular ACCELERATION is also known as rotational acceleration. It is a quantitative EXPRESSION of the change in angular velocity per UNIT TIME.

colour of matter?​Ans. The color of something is the color of light that it reflects most when light of all colors shines on it. ... If the electrons GIVE out EXACTLY the same light as they ABSORB, the substance is "colorless".. HOWEVER if the color of the light emitted is different from the color absorbed, then the substance has a color.

Platelets are tiny blood CELLS that help your body form CLOTS to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the SITE of DAMAGE and form a PLUG (clot) to fix the damage

tion:If the number of turns in the coil of galvanometer are decreases then the RESISTANCE of galvanometer decreases. Explanation: The wire's resistance is proportional to its LENGTH. The length of the wire LOWERS as the number of turns is reduced, and THUS the resistance FALLS.

The masses of two BLOCKS are 2kg and 1kg, the time is 2sec.The acceleration of masses is given as,a= (m 2 +m 1 )(m 2 −m 1 )g = (2+1)(2−1)g = 3g The acceleration of the centre of MASS is given as,a cm = (m 2 +m 1 )(m 2 −m 1 )× 3g = (2+1)(2−1)× 3g = 9G The distance travelled by centre of mass is given as,s= 21 at 2 = 21 × 9g ×4=2.22mThus, the distance travelled by the centre of mass is 2.22m.Explanation:hope it is useful

This is how they do it. LIQUID nitrogen is often referred to by the abbreviation, LN2. Liquid nitrogen is a diatomic liquid, which MEANS that the diatomic character of the COVALENT N bonding in N2 gas is retained after liquefaction. Di meaning TWO, ATOMIC meaning atoms, or two atoms that form a molecule.please mark as brainliest.

:-RECOIL velocity of the gun is 1.33 m/s .Explanation :-We have :-→ Mass of the bullet (m) = 30 g = 0.03 kg→ Mass of the gun (M) = 9 kg→ Velocity of the bullet (m) = 400 m/sTo find :-→ Recoil velocity of the gun (V) .________________________________After the bullet is fired, the gun will recoil in the opposite direction (backwards) . So the value of recoil velocity will be -V m/s .According to "Law of CONSERVATION of Momentum", total momentum of the system will remain conserved. So, by using this concept, we have :-⇒ M(-V) + mv = 0⇒ -MV = -mv⇒ V = -mv/(-M)⇒ V = mv/MPutting VALUES in the obtained FORMULA, we get :-V = mv/M⇒ V = (0.03 × 400)/9⇒ V = 12/9⇒ V = 1.33 m/s

-A ball of mass 150 grams going at a SPEED of 20 metre per second is hit by a BAT if it moves BACK with the same velocity. To Find :-Change in momentumSolution :-We know that1 kg = 1000 g150 g = 150/1000150 g =0.15 kgMomentum = mv Δp = mv - muΔp = m(v - u)Δp = 0.15[(-20) - 20]Δp = 0.15[-40]Δp = -6 kg/msHenceMomentum is -6 kg m/s

⇒m1(v1−u1)t=−m2(v2−u2)t⇒m1(v1−u1)=− The above EQUATION represents that the TOTAL momentum of the SYSTEM after collision is EQUAL to the total momentum of the system before collision. THEREFORE, the law of conservation of momentum is proved.

nal force is a CONTACT force that ACTS in the opposite direction to the motion of an object. This force can cause OBJECTS in motion to come to rest, as they act in the opposite direction to its motion. E.g. - If you roll a ball on a surface, it WOULD come to rest after a SHORT while.

tion:CLEARLY, the speed of sound in an ideal gas is INDEPENDENT of pressure. THEREFORE, the speed of sound remains constant even if we change the pressure of the MEDIUM. So, the ratio of velocity of sound in air at 4ATM pressure and that at 1atm pressure will be 1:1.

static FRICTIONAL force was preventing movement in the first 2 cases and sorry I didn't UNDERSTAND the 2nd QUESTION

The temperature CHANGES it's optical activity. This depends on the wavelength of LIGHT used and the substance. From my own personal experience, a 633nm laser will result in little change in optical activity. A green (546.1nm) has a much more easily measurable change (if you are doing a lab).We have the equation[α]=αlcwhere [α] is the SPECIFIC rotation (at a specific temperature and wavelength), α is the observed rotation, l is the path length (through the sugar water), and c is the concentration (in this case the sugar).I'm not exactly sure why temperature changes the specific rotation, but my best guess (from experiments that I have done) is that temperature changes the polarization of the substance. (Should make sense if you think of how water INTERACTS with light at different temperatures) Our above equation is sometimes written as[α]Tλ=αlcWhere T is temperature and λ is the wavelength. So the only thing that can change in here is the ORIGINAL polarization of the substance.

In ATOMIC physics and quantum chemistry, the ELECTRON configuration is the distribution of electrons of an ATOM or molecule (or other physical structure) in atomic or molecular ORBITALS.
