No (1)

Range /PQ/ = u²sin2ΞΈ/g
u = 250ms-¹ 
ΞΈ =42°
= [250² x sin(2x42°)]/10
= (62,500 x sin84°)/10
= 6250 x 0.9945
= 6215.63m
=========================== 

(2)
(i) They are pure semiconductors with impurities less than 1 and have teravalent crystals 
(ii) Presence of mobile charge carriers is intrinsic property of material 
(iii) No doping or addition of impurities required. 
=========================== 

(4)
F = 50N
k = 100Nm-¹
F = ke
50 = 100e
e = 50/100 = 0.5m
Work done = (1/2)ke²
= 1/2 x 100 x 0.5²
= 25/2
= 12.5joules
=========================== 


No (5a)

A geostationary satellite is an earth orbiting satellite placed at an altitude of approximately 35,800km directly over the equator that revolves in the same direction which the earth rotates.

(5b)
(i) Gas lasers
(ii) Solid-state lasers

(5a)
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east).

(5b)
(i) Gas Lasers
(ii) Solid-State Lasers

(1xii)

(i) I avoid parallax error in the metre rule and stop

(ii) I avoid conical oscillation

(3a)

(i) Emf , F=3.00v

Tabulate

R(Ο€) : 2.0,5.0,10.0,12.0,15.0,20.0

V(v): 0.86,0.62,0.43,0.38,0.32,0.25

V^-1(v^-1): 1.1628,1.6129,2.3256,2.6316,3.1280,4

(3ix)

Slope (s) =Ξ”R/Ξ”v^-1

= 17.5-4.25/3.5-1.5

= 13.25/2

= 6.625

Intercept (c) = -5.75

(3x)

S=Ro alpha (please use the alpha sign)

6.625=0.85(alpha)

alpha = 6.625/0.85=7.79

C= -(Ro +Ξ²)

-5.75= - (0.85+Ξ²)

Ξ²= 5.75-0.85

Ξ²=4.9

(3)

(i) I avoided parallax error when taking readings from the

voltmeter

(ii) I ensured that the key was opened when reading is not

been taking
