Answer:
4.3 cm
Explanation:
We are given that
Width,d=70.3
Wavelength,
We have to find the width in cm of the pattern.
The angle for the first minimum m=1
The width of the pattern=
Answer:
either +z direction or -z direction.
Explanation:
The direction of the electric field, in an electromagnetic wave always is perpendicular to the direction of the magnetic field and the direction of propagation of the wave.
You assume a system of coordinates with the negative x axis as the west direction, and the y axis as the up direction
In this case, the wave is propagating toward the west (- x direction), and the magnetic field vector points up (+ y direction), then, it is mandatory that the electric field vector points either +z direction or -z direction.
Her acceleration would increase, if mass decreases than the acceleration would increase
The June solstice in the Northern hemisphere is the summer solstice. The June Solstice in the Southern hemisphere is the winter solstice. The summer solstice is equivalent to the longest day while the winter solstice is equivalent to the shortest day. Therefore on the local sky, when is the June solstice we have have the longest day (longest path of sun in the sky) in the Northern hemisphere and the shortest day (shortest path of sun in the sky) in the Southern hemisphere.
The answer to this question would be: internal validity
Placebo effect happens when someone feels that they are getting better just because they got a drug, not by the substance inside the drug. That means even if the drug is empty the person can feel that it works.
Placebo effect can decrease the actual effect of the drug, thus decreasing the internal validity.
