(3)Explain magnetic separation method. |
|
Answer» ong>Explanation: Magnetic separation is the process of separating components of MIXTURES by USING magnets to attract magnetic materials.The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as Ferromagnetism/ferromagnetic (materials strongly AFFECTED by magnetic fields) and paramagnetic (materials that are less affected) but the effect is A large diversity of mechanical means are used to separate magnetic materials.During magnetic separation, magnets are situated inside two separator drums which bear liquids. Due to the magnets, magnetic particles are being DRIFTED by the movement of the drums. This can CREATE a magnetic concentrate (e.g. an ore concentrate). |

(i) Name any three parts in plant cell which differentiate it from an animal cell and mention their function. |
|
Answer» ong>Answer: • Cell Wall Plants possess cell wall while animal cells don't. • CONTRACTILE Vacuole Though it is present in both plant and animal cells, the size of a contractile vacuole is larger in plant cells. It is mainly DUE to the reason that plants do not have any other method of osmo-regulation. • Plastids Plant cells have organelles called plastids which help them in PHOTOSYNTHESIS. ANIMALS don't have plastids. |

Acceleration of a particle is given by a = t3 - 3t2 + 5, where t = time in seconds and a =acceleration in m/s2. Velocity of the particlewhen t = 2 sec is 8 m/s. velocity of the particlewhen t = 4 sec isans.22 m/s32 m/s25 m/s28 m/s |
|
Answer» ong>ANSWER: The answer is 32 m/s. Explanation: a = t^3 - 3t^2 On differentiating, ∆v = 3t^2 - 6t v - 8 = 3 × ( 4^2 - 2^2 ) - ( 6×4 - 6×2 ) v - 8 = 3 × ( 16 - 4 ) - ( 24 - 12 ) v = 36 - 12 + 8 v = 24 + 8 v = 32 m/s |

Acceleration of a particle is given by a = t3 – 3t2 + 5, where t = time in seconds and a =acceleration in m/s2. Velocity of the particlewhen t = 2 sec is 8 m/s. velocity of the particlewhen t = 4 sec isans.22 m/s32 m/s25 m/s28 m/s |
|
Answer» ong>Answer: 22 m/s Explanation: velocity = ∫a .DT = ∫(t³ - 3t² + 5) dt = (t⁴/4) - t³ + 5t + C
At t = 2, velocity is 8 m/s velocity = (2⁴/4) - 2³ + 5(2) + C 8 = 4 - 8 + 10 + C 2 = C Therefore, at t = 4 velocity = (4⁴/4) - 4³ + 5(4) + C = 4³ - 4³ + 20 + 2 {C=2} = 22 m/s |

A motor cycle and rider having a total weight W=1500N travels in a vertical plane following acurve of radius r=50m at a speed of 10m/sec.Compute the thrust exerted by the road as itpasses over the crest C on the curve as shownin the Fig. Assume g=10m/s2ans.1600N1500N1000N1200N |
|
Answer» >
In CASES like these, the thrust (or normal) exerted by the road is the sum or difference of the weight of the body and centripetal force. In this case,. thrust = weight - centripetal force = mg - m v^2 / r = 1500 - (1500/10) × ( 10^2 ) / 50 = 1500 - 150 × 100 / 50 = 1500 - 300 = 1200 N PS- The FIGURE is not given and the question isn't as clear, but this is what I THINK the question is asking.

Safety must not be compromised and some ground rules need to be followed FIRST. The basic guidelines regarding the safe handling of electricity documented below will help you while working with electricity. 1. Avoid water at all times when working with electricity. Never touch or try repairing any electrical equipment or circuits with wet hands. It increases the conductivity of the electric current. 2. Never use equipment with frayed cords, damaged insulation or broken plugs. 3. If you are working on any receptacle at your home then always turn off the mains. It is also a good idea to put up a sign on the service panel so that nobody turns the main switch ON by accident. 4. Always use insulated tools while working.

State Newton's second law of montion . Derive f=ma |
|
Answer» ong>ANSWER: Newton's second law of motion PERTAINS to the behavior of objects for which all existing forces are not BALANCED. The second law states that the ACCELERATION of an OBJECT is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. |

|
Answer» Laws of REFRACTION state that: The incident ray refracted ray, and the NORMAL to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. This is also KNOWN as Snell's law of refraction The term 'absolute refractive index' of a medium is defined as the ratio of the velocity of light in a VACUUM to the velocity of light in the medium refractive index= speed of light in air / speed of light in the given medium HOPE it has helped you |
