## NECO Physics Questions Essay Questions and Answer

PHYSICS PAPER II
Paper 2 will last for 1 hour

(9a)
(i) Cross sectional area of plates
(ii) Distanace between plates

(9b)
Given:
M=6kg
D=3m
G=6.67*10^-11 Nm^2kg^-2
using:
F= Gm^2/d^2
F= 6.667*10^-11*6^2/3^2
F= 2.668*10^-10N

(12ai)
A trajectory is the path traced by a projectile

(12aii)
(i) the fired bullet
(ii) thrown javelin
(iii) thrown bomb

(12b)
(i)A scalar quantity has no direction while vector quantity has direction
(ii) Scalars can be added and subtracted easily by using ordinary algebra while vector quantity however have to be added or subtracted by vector diagrams and law like parallelogram,triangle law and resolution of vectors.

(12ci)
DIAGRAM

(12cii)
(i) From the diagram
slope Bc = CD/BD
14=(V-20)/20
V-20=280
V=280+20
Final velocity V=300mls

(ii) Total distance= Area of rectangle OABFO+Area Of Trapezium FBCEF
=(OA*OF) + [1/2(BF+CE)FE]
=(20*40) + [1/2(20+300)20]
=800+3200
=400metres

(1a)
water passes through a dam, and into a river below. The more water that passes through a
dam, the more energy is produced. Once a dam is
built, an artificial man-made lake is created behind the dam. Electricity is produced by a device called a turbine.
Turbines contain metal coils surrounded by magnets. When the magnets spin over the metal coils, electricity is produced. Turbines are located inside dams. The falling water spins the magnets.

(1b)
Given:
M=10
U=?
V=mu
F=+5cm
V=10u(virtual image)
using the real is positive convention
1/f=1/u+1/v
1/5=1/u-1/10u
1/5=10-1/10u
1/5=9/10u
10u=45
u=45/10
u=4.5cm
The object must be placed 4.5cm from the microscope. • Anunawa says:
