o.k. this is what I came up with.
F = qvB
u = 1/u0 x B^2 (u0 being the permittivity of free space 4pie-7)
since u is the same as the "u" in the first equation, I used 1390 = 1/u0 x B^2 to calculate B to be 4.179e-2
then multiplied B by 1.6e-8 x 6e4 (velocity x charge) to get FB =...
Holy Cow. You're right. not sure where that number came from.
The actual answer I got (corrected calculations): 7.038e-4 unfortunately still wrong.
Thanks.
Homework Statement
A sound wave is incident on a pool of fresh water. The sound enters the water perpendicularly and travels a distance of 0.52 m before striking a 0.18 m thick copper block lying on the bottom. The sound passes through the block, reflects from the bottom surface of the block...
Homework Statement
The average intensity of sunlight reaching the Earth is 1390 W / m2. A charge of 1.60 10-8 C is placed in the path of this electromagnetic wave.
(a) What is the magnitude of the maximum electric force that the charge experiences?
1.637 N
(b) If the charge is moving...
PLEEASE HELP! I AM LOST! Thank you.
I have two questions:
1. Electromagnetic waves also can form standing waves. In a standing wave pattern formed from microwaves, the distance between a node and an adjacent antinode is 0.44 cm. What is the microwave frequency.
I keep getting the wrong...
You have to divide the distances / speed of sound to get the two times, subtract, then multiply by speed of light.
remember: the reporter hears the sound at the exact same time as the viewer. you have to adjust the equation for the time that it takes both individuals to hear the sound and then...
