Answer:
0.00384 kg/m
Explanation:
The fundamental frequency of string waves is given by
For some tension (F) and length (L)
Fundamental frequency of G string
Fundamental frequency of E string
Linear mass density of E string is
So,
The linear density of the G string is 0.00384 kg/m
Answer:
(C) 40m/s
Explanation:
Given;
spring constant of the catapult, k = 10,000 N/m
compression of the spring, x = 0.5 m
mass of the launched object, m = 1.56 kg
Apply the principle of conservation of energy;
Elastic potential energy of the catapult = kinetic energy of the target launched.
¹/₂kx² = ¹/₂mv²
where;
v is the target's velocity as it leaves the catapult
kx² = mv²
v² = kx² / m
v² = (10000 x 0.5²) / (1.56)
v² = 1602.56
v = √1602.56
v = 40.03 m/s
v ≅ 40 m/s
Therefore, the target's velocity as it leaves the spring is 40 m/s
Answer:
A greater period.
Explanation:
The period of a simple pendulum is represented by the following formula:
Where:
- Length of the pendulum
- Gravity constant
Given that gravity constant in the Moon is less than on Earth, period shall be greater.
