C) Natural and Artificial sources
Answer:
Acceleration is the change in velocity, not the velocity itself; therefore, an object can have zero velocity but not zero acceleration because the velocity will be changing.
Answer:
1.6 x 10^-5 T
Explanation:
i = 4 A
r = 0.05 m
The magnetic field due to long wire at a distance r is given by
B = 10^-7 x 2 x 4 / 0.05
B = 1.6 x 10^-5 T
Thermal Expansion. best describes the increase in a materials volume
The answer is B frequency. When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases
