Answer:
Percentage increase in the fundamental frequency is
d)-14.02%
Explanation:
As we know that fundamental frequency of the wave in string is given as
now it is given that tension is increased by 30%
so here we will have
now new value of fundamental frequency is given as
now we have
so here percentage change in the fundamental frequency is given as
% change = 14.02%
Answer:
Clockwise and counter clockwises, depands.
Explanation:
The direction of current in a loop of wire in a magnatic field depands on the direction in which the loop is moved and the applied magnatic field.
this is determined by what is called right hand rule.
I will give one scenario, let's say that the loop is moved upwards and the applied magnatic field is into the page (if you drew the loop in 2D on a piece of paper), in this case the direction would be clockwise.
The answer is either c or b
Happy hanukkah or christmas people
The third one because it is a small one and it had high and high temp so it has the most modecules.
