Answer:
All of the statements are correct
Explanation:
Hello!
All of the statements are rigth. You can know this by examining the Lorentz Force:
a )
The dependence on the charge sign can be inferrend by the term q which is the particle's charge. If it changes sign, the force also does.
b)
Although we usually deal with constant magntic Fields, they could also be position dependent, for example the magnetic field of a wire. The fild of teh force will also inherit this position dependence, that is:
c)
d)
Again, from the equation of the force or Lorentz force, we can see that this statement is true.
d)
The validity of this statement is given by the cross product between the velocity (which points twoards the direction of motion of the particle) and the magnetic field
I’m not completely sure but if I had to guess I would say lithium oxide
Answer:
D) 255pa
Explanation:
pressure= force/area
force = weight
weight= mass* gravitational acceleration
weight= 0.2kg*10m/s²
weight= 2N
area= πr² where r=1/2diameter
r=1/2diameter
r=1/2(10cm)
r=5cm or 0.05m
area= πr². where π 's approximate value is 3.14
area=3.14(0.05m)²
area=3.14 * 0.0025m²
area=0.00785m²
pressure= force/area
pressure=2N/0.00785m²
pressure=255pa approximately
Your answer should be (Bold): The Nuremberg Laws, as they became known, did not define a "Jew" as someone with particular religious beliefs. Instead, anyone who had three or four Jewish grandparents was defined as a Jew, regardless of whether that individual identified himself or herself as a Jew or belonged to the Jewish religious community. - Hope this helps! =^-^=
