I believe the answer is: C.)weight lifting twice a week
Weight lifting increase the muscle composition in your body. When you have higher muscle composition, your body would be able to generate more power which might resulted an increase in throwing distance.

Answer:
a. Bar A is a magnet
b. Bar B is a metal or magnetic material
c. Bar D is a non-magnetic material
Explanation:
a. Bar A
Since B attracts both A and C, it shows that A and C are both magnetic. So, it is either B and A are magnets or B and C are magnets or A and C are magnets. Also, since A and C sometime attract one another and sometimes repel one another, it means that they attract when their poles are opposite and repel when their poles are negative. This show that both A and C are magnets. Thus, A is a magnet.
b. Bar B
Since B is attracted to both A and C and we know that both A and C are magnets, it implies that B is a magnetic material. Since it does not repel either A or C.
c. Bar D
Since D does not attract A, B or C, D is a non-magnetic material. Since, only a magnetic material can be attracted to magnets and we have established that both A and C are magnets and that B is magnetic. Since D is not also attracted to B, it implies that D is thus non-magnetic.
Answer:
The height in which the book is dropped from is 1.28 m.
Explanation:
Mass of the book, m = 1.5 kg
initial velocity of the book, u = 0
final velocity of the bok, v = 5 m/s
The height in which the book is dropped from is given by;
v² = u² + 2gh
v² = 0 + 2gh
v² = 2gh
h = v² / 2g
h = (5)² / (2 x 9.8)
h = 1.28 m
Therefore, the height in which the book is dropped from is 1.28 m.
