Answer:
A) 
B) 
Explanation:
A) Using the Archimedes' force we can find the weight of water displaced:
Where:
: is the weight of the block in the air = 20.1 N
: is the weight of the block in the water = 15.3 N
Now, the mass of the water displaced is:
The volume of the block can be found using the mass of water displaced and the density of the water:
B) The density of the block can be found as follows:

FOUR USES OF CONCAVE MIRROR:Satellite dishes,headlights of a car, telescopes used for astronomical studies, and shaving mirrors because of there curved and reflective surface.
FIVE USES OF LENSES: Camera lens ,microscopes ,magnifying glass,eyeglasses,projector
Answer:
the friction force in the reverse direction is 200 *0.4=80 N.
the net forward force acting on the box is therefore
Fnet= 100 - 80 N
= 20 N
acceleration = Fnet / mass
=Fnet *g/(weight)
=20 *9.8/200 = 0.98 m/s^2
