Answer:
velocity of this in the direction of the Earth is 6.4 × m/s
Explanation:
given data
wavelength = 121.6 nm
wavelength = 124.2 nm
solution
we get here first change in wavelength that is
= 124.2 nm - 121.6 nm ...............1
= 2.6 nm
we get here velocity of direction of the Earth that is express as
............2
put here value we get v
v =
v = 6.4 × m/s
Answer:
Inducted Magnetic field will be toward from you
Inducted current direction will be counter clockwise.
Explanation:
Lenz's law states that the direction of the current induced in a wire by a changing magnetic field is such that the magnetic field created by the induced current opposes the initial changing magnetic field.
So if the field begins to decrease, the induced magnetic field would try to stop this, so its direction will be the same as the magnetic field, toward from you.
This induced magnetic field is produced by the current in the wire. If the inducted magnetic field will be toward you, the right hand rule says that the direction from the inducted current will be counter clockwise.
B an egg released from the ovary. It’s probably wrong
M1(mass of wood) = 4 kg
M2(mass of water) = 3 kg
V1(volume of wood) = 2 * V2(volume of water )
Density = mass/volume ======= volume = mass/density
Density of water is 1 kg/m3
V2 = M2/density of water
V2 = 3 kg/m3/1kg/m3
V2 = 3 m3
V1(volume of wood) = 2 * V2
V1 = 2 * 3m3
V1 = 6m3
Density of wood = M1 ( mass of wood)/ V1(volume of wood)
Density of wood = 4 kg/ 6m3 = 2/3 kg/m3
The blue line with triangles are a cold front. The red line with half circles are a warm front. The black H is high pressure. The black L is low pressure. The black dot is overcast skies. Finally the white circle with a line down and 4 lines off of that line is 40-knot wind
idk and dont understand
