Answer:
Linear mass density,
Explanation:
Given that,
Mass of the string, m = 0.3 g = 0.0003 kg
Length of the string, l = 1.5 m
The linear mass density of a string is defined as the mass of the string per unit length. Mathematically, it is given by :
or
So, the linear mass density of a string is . Hence, this is the required solution.
If you match the amount of static friction that can be generated when the object is at rest, it will not move because there is zero force the force has to be greater that the static friction in order to have it include motion. But if there was any more force will cause acceleration otherwise if it was lower force it will deceleration.
Answer:
The efficiency of a Stirling engine is 74%
Explanation:
Given:
Temperature of gas when it is cold K
Temperature of gas when it is hot K
The efficiency of a stirling engine,
∴
Therefore, the efficiency of a Stirling engine is 74%
Using the combined gas law of P1V1=P2V2 and plug it in you get (4)V1 for you don't have initial volume = (0.2)(500) --> 4V1=100, divide by the coefficient on both sides and you get V1=25
