Question 6
A
1200g
B
1000g
C
800g
D
400g
Explanation.
Mass = density x volume

400 x 2.5 = 1000g

Loss in mass = volume x density

= $$\frac{400}{2}$$ x 1 = 200g

Reading on spring balance = 1000 - 200g = 800g

Question 7
A
4J
B
15J
C
5J
D
100J
Explanation.
W = FS = 20 X 5

= 100J

Question 8
A
0.5ms-2
B
2.0ms-2
C
10.0ms-2
D
40.0ms-2
Explanation.
Slope = a = $$\frac{\deltav}{\deltat}$$

= $$\frac{50 - 10}{30 - 10}$$

= 2.0ms-2

Question 9
A
4.2ms-1
B
4.7ms-1
C
5.6ms-1
D
7.1ms-1
Explanation.
R = Ucos$$\theta$$ x t

U = $$\frac{R}{Cos \theta \times t}$$

= $$\frac{4.50}{Cos40N.25}$$

= 4.699m/s

Question 10
A
60g
B
80g
C
120g
D
200g
Explanation.
Clock-wise moment = Anti-clock wise

15 x m = 5 x 10

m = 200g
