pe semiconductor is a TYPE of material used in ELECTRONICS. It is made by adding an impurity to a pure semiconductor such as silicon or germanium. The impurities used may be phosphorus, arsenic, ANTIMONY, BISMUTH or some other chemical element. They are called donor impurities.

A) 10000 kgm/sB) 8 kgm/sExplanation:A) GIVEN, MASS = 2000 kg Velocity = 5 m/s Momentum = mass × velocity M = 2000 × 5 M = 10000 kg m/s B) Mass of BULLET =0.02 kgVelocity =400 m/sMomentum =0.02×400=8 kg.m/s

The RIGHT-hand rule imposes the following procedure for choosing one of the two directions. With the THUMB, INDEX, and MIDDLE fingers at right angles to each other (with the index finger pointed STRAIGHT), the middle finger points in the direction of c when the thumb represents a and the index finger represents b.Explanation:mark as brainliest

ht-hand rule imposes the following procedure for choosing one of the two DIRECTIONS. With the THUMB, index, and middle fingers at RIGHT angles to each other (with the index finger POINTED STRAIGHT), the middle finger points in the direction of c when the thumb represents a and the index finger represents b.

an exothermic REACTION is a ``reaction for which the OVERALL standard enthalpy CHANGE ΔH⚬ is NEGATIVE.''

ection of the force on the wire is determined by FLEMING's left-hand rule. The motor EFFECT is when a coil of current-carrying wire rotates DUE to its PRESENCE in a magnetic FIELD.

The CURRENT amplification factor or current GAIN of a TRANSISTOR is the RATIO of output current to the input current. If the transistor is connected on base mode the current gain α=IEIC and if the transistor is connected in common EMITTER mode, the current gain α=IBIC.

A concave lens of focal length 15 cm forms an image 10 cm from the lens. How far is the OBJECT PLACED from the lens? DRAW the RAY diagram. so the object is placed 30 cm away from the concave lens.

93.6kmph, 69 metres.Explanation:We have U as 72kmph. This is equal to 20 m/s. t= 3 seconds. To FIND final velocity, v, use the formulav=u+at=20+2*3= 26 m/s= 93.6 km/hr.To find distance, use formulas= UT +0.5at^(2).s=20*3 +2*9/269 m

tion:Here, m=120g=120×10 −3 kg=0.12 kg V =2 i^ +5 j^ ms −1 ∴v 2 = v . v =(2 i^ +5 j^ ).(2 i^ +5 j^ ) =4+25=29 m 2 s −2 KINETIC energy, K= 21 m.v 2 = 21 ×0.12 kg×(29 m 2 s −2 )=1.74 J.

Dimensional FORMULA of DensityThe dimensional formula of density is given by,[M1 L-3 T0]Where,M = MassL = LengthT = TimeDerivationDensity (ρ) = Mass × Volume-1 . . . . . (1)The dimensional formula of volume = [M0 L3 T0] . . . . (2)And, the dimensional formula of mass = [M1 L0 T0] . . . . (3)On substituting EQUATION (2) and (3) in equation (1) we get,Density = Mass × Volume-1Or, (ρ) = [M1 L0 T0] × [M0 L3 T0]-1 = [M1 L-3 T0]THEREFORE, density is dimensionally REPRESENTED as [M1 L-3 T0].
