Answer:
size get smaller maybe there is no object remaining
Answer:
If resistance increases current decreases.
Explanation:
- Current is <em>inversely proportional</em> to the resistance.
- from the relation given below, we can clearly see the relation between current and resistance;
V=IR
I ∝ 1/R
This relation shows that when resistance increases,current decreases.
Answer:
Explanation:
A general wave function is given by:

A: amplitude of the wave = 0.075m
k: wave number
w: angular frequency
a) You use the following expressions for the calculation of k, w, T and λ:



b) Hence, the wave function is:

c) for x=3m you have:

d) the speed of the medium:

you can see the velocity of the medium for example for x = 0:
