Answer:
Sublimation
Explanation:
It looks like solid transfer into gas directly.
Answer:
The drawing of the free body diagram is in the attachment.
Explanation:
In order to draw a<em> free body diagram</em>, you have to include in the drawing all the acting forces in the box for the given situation.
The acting forces are:
-The normal force (N), which is the contact force that the inclined plane applies to the box. This force is perpendicular to the contact surface.
-The weight force (W), which is due to the force of gravity on the box. The direction of the weight force is vertical (perpendicular to the ground)
-The friction force (Fs), which in this case is the static friction force because the box is in rest. The direction of this force is opposite to the direction of the movement.
Therefore, you have to draw the inclined plane, the box and the acting forces (See the attachment)
Answer:
The formula comes from Lorentz force law which includes both the electric and magnetic field. If the electric field is zero, the force law for just the magnetic field is <u>F=q(ν×B</u>) . Here, F is force and is a vector because the force acts in a direction. q is the charge of the particle. v is velocity and is a vector because the particle is moving in some direction. B is the magnetic flux density.
We can derive an expression for the magnetic force on a current by taking a sum of the magnetic forces on individual charges. (The forces add because they are in the same direction.) The force on an individual charge moving at the drift velocity vd. Since the magnitude of B is constant at every line element of the loop (circle) and it dot product with the line element is B dl everywhere, therefore
∮B dl=μ0 I
B ∮dl=μ0 I
B 2πr=μ0 I
B=μ02πr Id=μ0/4π I dl×rr3
Since, r can be written as r=(rcosθ,rsinθ,z) and dl as dl=(dl,0,0) And now, if we take the cross product we would get
dl×r=−z dlj^+rsinθk^
and therefore the magnitude of dB is equal to
dB=μ0/4π I |dl×r|/r3=μ0/4π I z2+r2sin2θ−−−−−−−−−−√dl/r3
Thus, magnetic field is depending on r,θ,z.

Florida is usually the state most affected by these storms because of its unique location. Florida is a peninsula with warm ocean currents on either side, which allows hurricanes to make land fall on either side of the state. Florida also receives variations of coastal and inland effects from hurricanes.

Index of refraction can be calculated using the following formula:
where in a vacuum and "n" is the index of refraction. So we must calculate our velocity by manipulating the index of refraction formula and isolate v and so:
We could go one by one and calculate the velocity or use logic. If you divide by a larger number the output will be a smaller number. Therefore, the answer would be n=1.62 is the slowest.
By that logic when n=1 light would travel the fastest of these four scenarios. The key thing to understand about these problems is that the speed of light slows down as it goes through a medium, in a vacuum it's 3 x 10^ 8 m/s but as it goes through say air or water light slows down.
