<span>False. The purpose of an experiment is to determine whether the independent variable affects the dependent variable, not the other way around. The independent variable is the one that is manipulated by the experimenter.</span>
Answer:
f = 3900(343 - 20.7) / (343 + 27.4) = 3,394 Hz
Answer:
The electric field is
Explanation:
Given that,
Radius = 0.357 m
Charge
Point charge
Distance = 0.815 m
We need to calculate the total electric field
Using formula of electric field
Where, q = point charge
r = distance
Put the value into the formula
Hence, The electric field is
Answer:
Asteroids smaller than planets and meteroids are small piece of an asteroid burns up upon enetering Earths atmosphere
Answer:
In metals there are free electrons at normal temperature so when we increase temperature it resistivity gets increases,so conductivity decreases,while in semiconductor the electrons are not free so when we increase the temperature the covalent bonds begin to break and the electron becomes free so conductivity get.
