Answer:
4.4857 seconds
No
Explanation:
L = Length of the pendulum = 5 m
g = Acceleration due to gravity = 9.81 m/s²
Time period is given by
The optimum time interval in between the pushes is 4.4857 seconds
It can be seen that the mass of the child is not used in the formula and hence changing the mass would not result in a different time period.
The length of the pendulum and the acceleration of gravity of the planet determines the time period.
The following statements are correct:
1. Graduated cylinder are used to measure volume.
2. Always read a graduated cylinder from the bottom of the meniscus.
Graduated cylinders are one of the instruments used to measure liquid substances in the laboratory. The most accurate way of reading measuring cylinder is to record the value at the bottom of the meniscus.
Answer:
Explanation: El músculo esquelético está formado por fibras musculares, rodeadas de una capa de tejido conjuntivo, denominada endomisio. Las fibras se reúnen en fascículos primarios, que también están rodeados por otra capa de tejido conjuntivo, esta vez, más grueso, denominada perimisio.
First, use a high-quality measurement tool. Next, measure carefully. Finally, repeat the measurement a few times. Hope it helps!
