<u>Increase the thickness of the wire</u> would decrease the resistance in a wire
Explanation:
Thicker wires have a larger cross-section that increases the surface area with which electrons can flow unimpeded. The thicker the wire, therefore, the lower the resistance.
Thin wires have very high resistance the reason the thin tungsten in a bulb glows because it is heated from the high resistance of many electrons trying to pass through a very small cross-section.
Answer: representative sample
Explanation:
A representative sample can be defined as a subset of the population. This sample includes subgroups that reflect the features of the larger group and are chosen for a specific purpose of study. For example, a classroom with 60 students having 30 females and 30 males, can generate a representative sample based on the gender differences.
Are breathing hard. This is because cardiovascular exercise makes the heart beat faster which in turn creates a need for more air.
Answer:
The time taken by spider to catch insect 1.5 ms
Explanation:
Given:
Linear mass density
Tension on the string N
Distance between web and insect lands m
From the formula of velocity in string,
First find the velocity and then find time,
The time taken is given by,
sec
ms
Therefore, the time taken by spider to catch insect 1.5 ms
