Qualitative data gives the information of quality which can not be measured in numbers. For example: Color of eyes, softness of skin.
Quantitative data is information of quantity that can be represented in numbers. For example length and mass of any object.
Zinc is a silver-gray metal is a qualitative data, here silver gray color is quality of zinc metal which can not be measured in numbers.
Chlorine has a density of 3.2 g/L is a quantitative data. The value of density can be compared with other elements by comparing the numbers.
Gallium is not found in nature is neither qualitative nor quantitative.
Nitrogen has a melting point of –210.00 °C is a quantitative data because this is expressed in numbers.
Aluminum is a solid is a qualitative data because it tells about the state of element which can not be measured in numbers.
Answer:
A stripe of magnetic information that is affixed to the back of a plastic credit or debit card.
Answer:
The maximum velocity is 1.58 m/s.
Explanation:
A spring pendulum with stiffness k = 100N/m is attached to an object of mass m = 0.1kg, pulls the object out of the equilibrium position by a distance of 5cm, and then lets go of the hand for the oscillating object. Calculate the achievable vmax.
Spring constant, K = 100 N/m
mass, m = 0.1 kg
Amplitude, A = 5 cm = 0.05 m
Let the angular frequency is w.
The maximum velocity is
