The velocity, frequency and wavelength of a wave are related by:
v = fλ
v = 32 x 0.5
v = 16 m/s
The answer is B.
Answer:
<em>The wave will be travelling in the y-axis</em>
Explanation:
An e-m wave has a spatially varying electric field that is always associated with a magnetic field that changes over time and vice versa. The electric field and the magnetic field oscillates perpendicularly to each other, and together form a wave that travels in a perpendicular direction to the magnetic and the electric field in space. The movement of the e-m wave through space is usually away from the source where it is generated. So, if the electric field travels in the z-axis, and the magnetic field travels through along the x-axis, then the e-m wave generated will travel in the y-axis direction.
The entire mass of the Earth at neutron star density would fit into a sphere of 305 m in diameter
Answer:
C) about 1/10 as great.
Explanation:
We use the relation between Impulse, I, and momentum, p:
the final speed is zero
We can see that the average Force is inversely proportional to the time, so if the time is 10 times bigger, the average Force is 1/10 as great
