WAEC 2016/17 PHYSICS PRACTICAL QUESTIONS AND ANSWERS

1(a)
V(cm)=10.0,15.0,20.0,25.0,30.0,35.0
U(cm)=47.0,48.5,50.0,51.5,53.0,54.5 respectively

Precautions
i I avoided drought to prevent swinging of the mass Q
ii I avoided parallax error in reading the metre rule
iii I avoided that the mass did not rest on the table

(1) b(i) Moment of a force about a point is the product of the force sF and the perpendicular
distance from the point to the line of force.
Example opening of door, turning of tap,riding of bicycle.

1 b(ii) (a) The principle of moment states that if a body is in equilibrium the the sum of the
clockwise turning moments acting upon it about any point equals the sum of the anticlockwise
turning moment about the same point.
(b) The term equilibrium meabs that when a body acted on by several forces and it does not
accelerate or rotate, it is said to be at equilibrium.

2bi)Heat Capacity: is the amount of heat required to change its temperature by one degree, and
has units of energy per
degree.
1b i Moment of a force about a point
The moment of a force about a point O is defined as the vector product (cross product)
Mo= r × F
where r = xi + yj + zk is the radius vector (position vector) drawn from O to the point of
application A of the force F , and F = Fx + Fy + Fz is the force vector acting on A.

No, you don't need to sit in lotus posture to ponder

Imagine we're playing pretenses and you're advised to emulate reflection. What present do you go into?
