Answer:
A) 0.50 mV
Explanation:
In this problem, we can think the wings of the bird as a metal rod moving across a magnetic field. So, and emf will be induced into the wings of the bird, according to the formula:
where
is the strength of the magnetic field
v = 13 m/s is the speed of the bird
L = 1.2 m is the wingspan of the bird
is the angle between the direction of motion and the direction of the magnetic field
Substituting numbers into the formula, we find
Answer:
depends on what type of car it is
Explanation:
Reproducible is the term where your answers are similar to other groups. If every other group has similar results as yours (only if you use the same measurements) your results are reproducible. If your results are different to every other group your results aren't reproducible. <span />
Answer:
According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.

Answer: gamma rays < ultraviolet light < radio waves
Explanation: We have to explain the ordering we take into account a relationship for electromagnetic wave, which is given by:
c=λ*ν c is the speed of light. λ and ν are the wavelegth and the frequency of the waves.
Then we also know that the high frequency of these radiation correspond to the gamma ray (10^18 1/s) while the lowest correspond to radio wave (10^8 1/s) so:
The ultraviolet ligth is ranged at frequencies of 10^16 1/s located bewteen gamma and radio radiation.
as large frequency lower wavelength we can order these radiations from short to long wavelengths as follows:
gamma rays < ultraviolet light < radio waves
