What is the resultant resistance of the circuit in the image shown?
8Ω
11Ω
4Ω
3.6Ω
Correct answer is A
No explanation has been provided for this answer.
Which of the following does NOT describe the Image formed by a plane minor?
Erect
Laterally inverted
Same distance from mirror as object
Magnified
Correct answer is D
The image formed by a plane mirror is always virtual (the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting.
Which of the following is not true of an electrical charge?
Positive charge means deficit electrons
Negative charge means excess of electrons
electric current means movement of electrons
All of the above
Correct answer is D
No explanation has been provided for this answer.
1360cm3
600cm3
240cm3
8000m3
Correct answer is B
Density=massvolume
⇒ 0.9gcm−3=mass400cm3=360g
without any loss in the frying process, we have
0.6gcm−3=360gv
v=360g0.6gcm−3=600cm3
A man walks 1km due east and then 1 km due north His displacement?
√2km N 45°E
1km N 30°E
1km N 15°E
√2km N 60°E
Correct answer is A
His movements 1km due east and then 1 km due north make a Right-Angled Triangle.
Using Pythagoras' theorem;
The Resultant becomes the Hypotenuse [h]
Hyp2 = Adj2 + \Opp(^2\)
Hyp2 = 12 + 12
Hyp2 = 2 → Hyp = √2
: Resultant = √2
DIRECTION TAN Ø = OPPADJ
TAN Ø = 11
Ø = TAN−1 [1]
Ø= 45°
Displacement is √2km N 45°E
