Answer:
0.70046 m/s²
2.732862 N
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
m = Mass of yo-yo = 0.3 kg
R = Radius of rolling disk = 5.1 cm
r = Radius of rod = 1 cm
For a rolling disks the acceleration is given by

The acceleration of the yo-yo is 0.70046 m/s²
The tension in the string will be

The tension in the string is 2.732862 N
Answer:
26
Explanation:
Total power of the circuit
P = V × I = 120 × 20 = 2400 W
Power of each bulb = 90 W
Number of bulbs which work without tripping
N = power of circuit / power of each bulb
N = 2400 / 90
N = 26.66
Number of bulbs should be integer so the number of bulbs be 26.
