Answer:
r = 1.56 m
Explanation:
B = μ₀I/2πr
r = μ₀I/2πB
I = 9.00 / 52.0 = 0.173 A
μ₀ = 4πe-7 T•m/A
r = 4πe-7(0.173)/2π(2.22e-8)
r = 2e-7(0.173)/(2.22e-8)
r = 1.5592... ≈ 1.56 m
Answer:
hence the y - component of the velocity is 50m/s
Answer:
The electron microscopes are uses the electron to produce the image of the any object.The area where the electron passes then that area appeaser white but on the other hand where the electron does not pass that area appears black.But this does not give any information about the color of light it shows only white and black areas.We also know that color is the property of photons ( light).So the microscopes does not produce color of the image.
Answer: There is only one Sun in the galaxy … that is the thing that rises in the morning and sets at night. However, there is a use of “sun” to signify any old star … nobody knows exactly there might be trillions out there
Explanation:
Answer:
v = 29.4m/s
Explanation:
Since the ball is dropped at rest,
u = 0m/s
a = 9.81m/s²
Using
v = u + at
After 3 seconds,
v = 0 + (9.81)(3)
v = 29.4m/s
