Answer:
A. 5.16 s.
B. 5.66 s.
Step-by-step explanation:
A.
For a simple harmonic motion,
T = 2pi (sqrt * (l/g))
Given:
L1 = 3 cm
T1 = 4 s
L2 = 5 cm
T2 = ?
4 = 2pi*sqrt(3/g)
g = 7.4
At, L2,
T2 = 2pi*sqrt(5/7.4)
= 5.16 s.
B.
M1 = M1
M2 = 2*M1
For a simple harmonic motion,
T = 2pi (sqrt * (m/k))
4 = 2pi (sqrt * (M1/k))
M1/k = 0.405
Inputting the above values,
T2 = 2pi (sqrt * (2*M1/k))
= 2pi (sqrt * (2 * 0.405))
= 5.66 s.
Answer:
√g *√g = g
Step-by-step explanation:
recall that any number or variable to the power of 1/2 can also be written as that variable or number under the radical.
So, we then have
√g * √g
Recall that when we multiply radicals, we multiply what is under our radicals together and then combine them under a new radical
√g * √g = √(g * g)
This gives us √(g²)
recall that the square root of a number or variable squared will merely result in the number or variable by itself (as these are reciprocate equations)
√(g²) = g
