When two circuit elements (e.g., light bulbs, resistors, etc.) are in PARALLEL, the voltage drop across each element must be the same.
(choice-b)
When the same two circuit elements are in SERIES, the current through each element must be the same.
This phenomenon can be describedby Hooke'slaw and expressed by the formula: F=k*deltax, where k is the spring's constant, and delta xis the displacement of the spring. Transposing the terms such that we want to know the value of k,
k = F/deltax = 100N/(22 cm - 20cm)
k = 50 N/cm
Answer:
<h3>The answer is 1.92 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 2.5 g
Volume = 1.3 cm³
We have
We have the final answer as
<h3>1.92 g/cm³</h3>
Hope this helps you
