Lol what i think i’ve heard of that story
The second statement is correct : Gravity is a force that pulls objects towards Earth's centre.
An atom is solid material
Answer:
0.5 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 0.060 kg
Period (T) = 1.4 s
Lenght (L) =?
NOTE:
1. Acceleration due to gravity (g) = 10 m/s²
2. Pi (π) = 3.14
The length of the pendulum can be obtained as follow:
T = 2π√(L/g)
1.4 = 2 × 3.14 × √(L/10)
1.4 = 6.28 × √(L/10)
Divide both side by 6.28
1.4 / 6.28 = √(L/10)
Take the square of both side
(1.4 / 6.28)² = L/10
Cross multiply
L = 10 × (1.4 / 6.28)²
L = 0.5 m
Therefore, the length of the pendulum is 0.5 m
