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.
Given; Mass m = 65.0 Kg; acceleration a = 1.25 m/s²
Required: Force F = ?
Formula: F =ma
F = (65.0 Kg)(1.25 m/s²)
F = 81.25 N
Answer:
The change in frequency hearded by an observer in the truck is f'= 636.36 Hz.
Explanation:
Vo= 36 m/s
Vf= 45 m/s
V= 342 m/s
f= 500 Hz
f'= f * ((V- (-Vo)) / (V - Vf)
f'= 636.36 Hz
The mass of the object is 0.0076 kg
Explanation:
The frequency of a mass-spring system (simple harmonic motion) is given by
where
f is the frequency
k is the spring constant
m is the mass
For the mass-spring system in this problem, we know:
k = 30 N/m is the spring constant
f = 10 Hz is the frequency
Solving the equation for m, we find the mass:

Answer:
An intensive property is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties include temperature, refractive index, density, and hardness of an object.
