By what factor should the length of a simple pendulum be changed in order to triple the period of vibration?
1 answer:
Answer:
increased by 9 times
Explanation:
As the period of a simple pendulum is defined as the following formula
where L is the length of the pendulum and g is the constant gravitational acceleration. Since L is under a square root, if you want to triple the period of vibration, L must be increased by 9 times so that

Actually Welcome to the Concept of the Kinematics.
1.) Distance travelled = 15+20 = 35 miles.
Ai the total distance covered is 35 miles.
2.) Displacement is the shortest distance from the initial point to the final point.
here it's ==> 20-15 = 5 miles
hence, displacement = 5 miles
Answer:
The time required by the impulse to travel from foot to brain equals 0.019 seconds
Explanation:
For uniform motion the distance, speed, time are related by the equation
In our case since the person is 1.90 meters tall so the nerve impulse will have to cover a distance of 1.90 meters at a speed of 100 m/s.
Hence the time required for the impulse to travel from foot to the brain can be calculated as
