Physics Essay Answer

(1)
Range /PQ/ = u²sin2θ/g
u = 250ms-¹
θ =42°
= [250² x sin(2×42°)]/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
===========================

(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
===========================

(7)
(i) Magnetic materials are materials having a magnetic domain and are attracted to an external magnetic field WHILE Non-magnetic materials are materials that are not attracted to an external magnetic field.
(ii) The magnetic domains of magnetic materials are aligned either parallel or antiparallel arrangements thus they can respond to a magnetic field when they are under the influence of an external magnetic field WHILE The magnetic domains of non-magnetic materials are arranged in a random manner in such a way that the magnetic moments of these domains are cancelled out. Thus, they do not respond to a magnetic field.
(iii) Magnetic materials are used to make permanent magnets are the parts of operating systems where magnetic properties are required WHILE Non-magnetic materials are used to make parts of some operating systems where no magnetic effect are expected and other things such as cases of compasses.

===========================

(8ai)
The law of inertia states that a body will continue in its present state of rest or if it is in motion, will continue to move with uniform speed in a straight line unless it is acted upon by a force.

(8aii)
When the brakes of the moving vehicle are suddenly applied, or the passengers jerks forward as thet tend to continue in a straight line. The seat belt helps to provide a backward force and reduces injuries.

(8bi)
The moment of a force about a fixed point is the product of the force and the perpendicular distance at the point to the line of action of the force.

(8bii)
(I) Draw the Diagram

(II) clock wise moment = Anticlock wise moment
T x 1.5 = 54 x 0.5
T = 54×0.5/1.5
T = 18N

(III) F + T = w
F = w – T
F = 54 – 8
F = 36N

(8c)
[TABULATE]

=STATIC FRICTION=
(i) Acts whete the surfacrs are at rest
(ii) It had ahighet coefficient value
(iii) Increases linearly wuth the applied force untill it reaches a maximum value.

=DYNAMIC FRICTION=
(i) Acts where the surfaces have relative motion
(ii) Has a lower coefficient value
(iii) Remains constant regardless of the force applied.

(8d)
By increasing the number of pulleys.
